Winningat badcgammonrequiresmastering twophases ofthe game: dynamic checkerpIq (using your checkers as weapons to pin your opponent in awkward positions) and aggressivecube action (using the doubliig cube to maximize your wins in good positions and minimize your losses in bad positions). Both parts of the game are essential. Wkhout sharp checker play, you wont create the sorts af positions where you can outmaneuver and outplay your opponents.Without skillful use of the doubling cube, you won't earn as much from your good positions as you should. Ifyou're goingto be a big winner, you've got to master both of these elements.
In this book, I'll show you the secrets of aggressive checker and cube play as practiced by the greatest masters of the game. You'll lmn how to make your checkers work in multiple ways, how to build primes quickly when you need them, and how to drop back inro holding positions and back games for more win-
ning chances late in the game. You'll also lean the masterj~retsforoffering timely doubles,andhowto decide whether a cube i s a take or a drop.
By the time you've finished rmding, you'll be &ng to incorporate thest ideas in your own v. The results wiU be impressive. Your checker pky will put extra pressure on your opponents, forcing them into cramped, a w h d positions. Your cubcs will come at just the right moment, forcing tough decisions. Finally, your i m p d technique will let you bring your games to winning condusions,avoidingtheupmand turnarounds that will plague your o p p o m . Let's get s d !
The best way to study backgxnmon Is by looking at d games played by master players. There you'll h d , instead of contrived situations, the sort of dificuic yet fascinating positions that occur when Gackgammon i s played by competitors who redy undersmnd the game. In thls book I've collected five of the most interesting games h m master play in the last few ymrs. Each of the players is a first-class pro playing at the top of hi game. a
My fim book, adckgmtnonfir Wnnm, gave you a solid foundation for mastering the basic strategies of the game. In the games I've p i c h i for this book, you're going to be introduced to a higher level of play, full of new ideas that we haven't encountered before. R d carefully; there's probably a lot here that you've never seen. By she time you've worked yourway through the
whole book, your undersmnding and your play will have advanced several I d .
Backgammon is a game best studied not passively. It's tasy to MI into the trap of reading through a book quickly, noringwhatthe author has to say, tcllingyoum1F"Ohycs, hat's prettyobvious,"and moving on. Siac backgammon moves are all j u t sittingthere, waiting to be found, it's tempting to think that you would surely have found all these movts had you k n sittingat the table. lfyou'relthinkingthisway, you're studying p i r e l y .
I recommend a more active approach to reading chi book, Treat each game like a quiz, especially the first time you read through it.Tryusing a piece of paper or cardboard to cover a player's roll andmovc.Thcnmove the paper to uncover just the dice roll. Ask youtseif, "Whatwould I play here?"Ifyou want to, write down your play on a separate piace ofpaper. Now expose the actual play and compare it to what you would have done.
By reading and t&g yourself in this way, you'll compile a Iist of the plays you would haw made difkrently. Now the arplanations will be more m a n in&l, since youbealreadydone the work of grappling with the problem At the same time, you should also readclosely the wmrncna on the playsyou made correctly, since my wmmcnts may bring out some fkatum of the position you hadn't considerod.
Backgammon tournaments ate heH dl over the world and throughout theyear. On anygivenweekend,there will be local tournaments across the United States and throughout Europe. The game is currentlycatching on in SouthAmerica, and many new clubs and events are starting there.
The biggest tournaments are frequent enough ta comprise a~ informal tour,and a handful of professional players make the circuit. The big events include the Swiss tournament in Gstaad and St. Moria in March. Then it's on to St. Tropez and Zas Vcgas in April and May, Venice infune, andTheWorld Championship in Monte Carlo in July. A brief stopover in Cannes is followed by the highlight of the tour, the World Cup in Dallas. October is dedicated to the South American tournaments in Sao Paulo, Ria de Janiem, and Buenos Aires.Theseason finisheswith the Las Vegas Open and Pro Am DouMes Championship in November.
Tournamentsare great places to meet newplayers, take a look at new boards and quipmcnt, and pickup n m ofdubs opening.Mast top tournamens have a lecture series for beginners and inttrmcdiates, while pros: art always available for private lessons. Don't be intimidated if you're a beginner. Every tournament has sections and activities designedespeciallyfor newcomers. Besides,ifyou absorb the ltssons in this book, you won't stay a beginner for long? WKQAMMON TOURNAMENTS Backgammon tournaments arc run somewhat like tennis tournaments, using an elimination format In the first round, players are p a i d at random. If the numberof players is not qua1to a power of 2 (16,32, 64,128, and so forth),some players dl receive a bye, which is a free pass ro the ncm round. Each round,half the players arc climinatcd, until only two players remain.T h a two playerscompetein the finals for the title of champion.
Eliminated players are dropped inm a new m t , mlled the Consolation,Losers in the Consolationare dropped into a final event, the Last Chance.Matchts in the Consolation and Last Chance are typically shorter than in the main m n t , In a ypical tournament, about60%ofthe prize money k domed to the main mmt, with 30% in the
Cansolationand 10%in the Last Chance. Of course, the exact percentages and prizes are up to the tournament organizer. In addition to the main tournament with its Consolation and Last Chance,there are usudy manyjackpotsandside wents ping on atthe same time. Some players have been knawn ro play aver 100 matches during the course of a week-long competition.
A largc tournament may take 7-9 days to complete. Smaller regional events might be held over just a long weekend. A purely local event can be completed in a single day. Matches in regional and local events are much shorter than in the big international competitions. SPECEAL RULES FOR
TOURNAMENT P I A Y Tournament play is structured around matches that are played to a specified number of points. By tta&tion, the number of points in a match is always OM.In a local murnamenx, for example, the matches might m t at 9 points, increasing as rounds are pIayed to a 15 point final match. The longerthcmatch, the more skill is involved in the outcome. As in money play, the doublingcube is used. Competitors play gama and add the points won in tach game to their total sfore. When one player reaches the
dcsirad rod, the match is over and he is the winner. In tournament play, you don't have to doubIe to win a gammon. Thafs different from maney play, where in
most dubs the doubling cube must be turned for a prnmon or backgammon to be scored (the Jacoby Rule). Toward the end ofa match, the Crawford Rule comes into play. hventad many years ago byJohn Crawford, the Crawford rule statcs that when a player's score teaches one point from victory, hs i opponent cannot double in the very next game. If the mat& continues beyond the next game, the cube can be usod normdy.
For example, Smith and Joncs are playing a Ppoint match, and Smith wins a p e to make the score: Smith 8, Jones 4. The next game is the Crawford Game, andJonesannot double in this p e . (Smith, ofcourse, has no reason to double.) M s a y Jontswins one point in the Crawfod Game to mike the score 8 to 5. In the following game, normal rules are back in e f k and Jonescan double as soon as he wishes. Disputes between the players are settled by calling the tournammt director, who will make a ruling. In certain exceptional casts, a panel of experienced playcrs may be convened to make a ruling
THE MAJOR TOURNAMENTS Like golf and tennis, backgammon has a few events whose irnpomce dwarfs the other tournaments. Here are a few of the biggest and most prestigious tournaments in modern backgammon.

THE WORLD CUP The most important tournament in backgammon is the World Cup, heid every other year in August in Dallas. What sepatates the World Cup from dl other events is the extreme length of iw matches. Each round in h e main event is a best three out of five, 1P point series. In the Consolation, matches start at 25 points (longer than the finals at most tournaments) and increase to a 29 point final. Chess docks are used to time each match and ensure reasonablyspeedyplay (as well as adda little extrapressuse).TheWorld Cup is the most d8icult tournament in backpnmon to win, and in fact, no one but a top world-class pro has wer won the went.

a ways off. 56. Black 53: 23/15
As long as White is on the bat, Blacks strategy is srraightfod+r as we say in backgammon, *A rnarrer of technique." His f i r s goal is to complete a 6point prime so that White's checker will not be able to escape. Ta do this, Black will leave the c h e k slottd on the 7-point, and prepare to cover it.
Right now he has ones to cover from the 8-point. By moving to the 15-point, he also gives himself eights to cover. Nmt turn, he'll move the checker on the I5point to within direct range ofthe 7-point (someplaae where a single number on a die could cover), and then start his other checkers moving. The faint of heart might now inquire, *Isn't Black risking a loss if White rolls a 16 from the bar?" The answer is, not rally. First of all, 16 is a great shot whether Black has a checker on the 7 or not. Second, men if White rolls the 16, Black will have plenty of chancesto hit the chackeras it tries to come around the board. And finally, the long-run danger that would result from nwer making a 6-point prime outweighs the short-run risk of a 16.
Plays h a t masters make routinely, likt leaving the bar slotted in this position, look bold to the uninitiated. Once you understand the reasons behind the pIay, however, it's not bdd at all, simply logical.
57. White stays out.
61. White stays out. By the way, Wh~teis quite happy t~ smy on the bar hr as long as possible! Why?He has noihing to gain by enteringnow, sincehe can't escape. But ifhedoes enter, he might then &ow an ace or a deuce, exposing a new
checker to a hit. As we saw bebre, Black canonly become a big favorite in this position by hitting, then dosing out, a second checker. If White sits on the bar long enough, Black dl eventuallybe forced ;to dose his ace-point, and that variation will then never occur.
Diagram 57: Black on roll
58. Black31: 817 15/12 Mission accornplkhd. Black has a full prime, so White cannot escape once he enters. B M s next job is to bring a spare c h e h into position to slot the acepoint. 59. White stays out.

69. White stays out. White has stayed out for eight consecutive turns! That's very unlikely. The odds of that o c m i n g are about 17-1 against, as a matter of fact. However, it's been a very lucky break far White. He's never had to a p s e a second checker, and B1ack"smen are almost all the way home.

To kOK,White will have to cross two quadrants to get hs checker into the home board, then bear off seven checkers.That's a total of nine crossovers. (A crossover is just a move of a dLecker &om one quadrant to anorher, or off the board. Counting crossovers is a quick way of getung an estimate of who's ahead in the race). Black, meanwhile, is on roll needing 13 crossovers. It looks like White is ahead, but remember that Black is pretty much guaranoed to bear off two checkers each turn, while if White rolls small numbers, he may
fail to get a crossover. 80. Black 53: 5/off SloR A good roll, taking men off the highest points. 81. White 33: 9/21. Exmilent!White should 'be able to redouble next turn.

White wins 8 points. SUMMARY: The game begins with an all-out svuggle for controlof key points, characteristic of modem backgammon at its best. Svobodny jumps out to an arly lead, but mi= a chance to give a good double on move 11. Over the nem few moves Magriel's position improves as he builds a block of his own. Finally Svobodny gets to o h another good double as Magriel i s forced to expose a couple of blots. A quick hit leads to Magriel's playing a classic, well-timed 1-2 back p. Magriel shows p o d defensive tdmique in opening the 2-point at just the right time. His good technique pays offas Svobdny leaves a shot and gets hit. Magriel quickly redoubles and completes a full prime, but Svobodny stays on the bar and thwarts Magriel's plan to catch a second checker. Svobodny eventually enters from the bar as soon as Magriel opens h is board. He gets around quickly enough to win by one roll.
has to take certain risks. Hi blots on the 16 and 15points are exposed to hits if Black throws any eight or mine. All told, Blackwill be able to hit a blot about one time in t h e . Joe Sylvcstes burst onto the backgammon scene by winning the World Amateur Championship in 1983. He has since won many Amaim tournaments including the Reno tournament from which this game is taken. He has an especially h e record in the World Cup, winning World Cup I in 1988 and finishing second in World Cup IV in 1994.
This gamewas played in the finals of the Reno Master's tournamenr of 1992. Sylvester was leading 5-1 in the 25-point match, which he e v e n d l y won, 25-22. 1. Wkite 43: 12116 12115 In top-flight backgammon today, there are several popular ways of playing an opening 43, each with its own adherents. The idea of Snelling's play is to bring down builders to make the kqr 20-point, 21-point, and 18-point.To achieve this buildingpotential, White
Two other phys uy to achieve a balance between budding and splitting with a bit lcss risk. The play which has b a n most popular for the part 15 years or so is 115 12/15. The checker on the 15-point gives White some new point-making numbers, like 62,5 1, and 63, while the split to the 5-point preparts to make the most valuable anchor. The c h d e r on the 15-point is exposed only to nines, so W h i t e is less likely to fall behind in the race after this play. S P L l P r e l W G IN THE OPENINQ A new play, which has been gaining popularity in the last few years, is 114 12116. For building purposes, the checker on the 16-point is actually a little more valuable than a checker on the 15-point, as it generates more new point-making combinations.
The idea of splitting to the Cpoint rather than the 5point is part of a new theory of splitting: Dm't split to thepoint cbatyuropponmtMOSTwanf~ to d e , ifyou &ma ckodcc. The point that Black most wants to make in this position is his 5-point. If you split there, and he points on you, he's accomplished twa objactives at on= puttingyou on the bar and making the best point
in hii b o d .
If White splits to the 4 p i n t insttad, Black can accomplish one o b j d w at most. He can point on Wire, or he can make hi best point, but he mn't do both at once.

Diagram 62: Bkck on roll 2. Black 53: 24116* Black could &o make his 3-point with this roll, but he chooses to hit instead. That's right.
Diagram 63:Black on roll
4. Black 54: BarllG* Black hits, although there's another good play: Bar120 24/20 (making the 20point in thiswayi s known as *A Barabino," in honor of Rick Barabino,who has rolled this number in many game-savhgsituations).Hitting here is right, however, for the same reason as in the comment to m m 2.
5. White stays out. White rolls 66 and stays on the bar. A badbreak, as that was the only number that wouldn't let him enter. One reason that hitting is so pawerful in the early game is that these disaster shots arc always lurking around when you're on the bar.
6. 81ilck21: 615* 13111 Simple and very strong. Sylvester unsmch hi two big points, puts a second White &checker on the bar, and prepares to build the 5-point. It's hard to do more with a single roll. 7. White 62: k t 2

Diagram 64:Black en roll 8. BIack doubles to 2. A m n g double. Black is ahead in ail key phases of rhe game. He has a big lead in the race (1 56 pips to I89), he has escaped a chadEer while W u t e has four men back, and he has plenty of builders in position to work on hi prime. Making the 5-point is virtually a sure thing, and the bat or the 4-point should follow soon.
A fine double by Sylvester. 9. White takes. Just bemuse Black has a
double doesn't mean White should drop. Next turn White wilI likely face just a two pointboard.ThatmeansW h i t e shouldhavenotrouble entering and starting hi own development. White could crate a high anchorgame, a massiveback game,
or a counter-prime of his own. He's certainly an underdog, but there's plenty of play left. Good take by Sncllings. 10. Black55: 16/11 1313 813 A constructive shot, although it's one of the few numbus that doesn't make the 5-point. Black maGes the 3-point and the 11-point, preparing for more
progress next turn. 11. W h i t e mays out. Dancing now is much more serious &an dancing two nzms ago. That dance just gave Black a healthy initiative; thls turn on the bar may give Black the time to pin

If Black can capture the bpoint and force W h i t e to play just a pure ace-point game, White's winning chanccs will be in the 20% to 30%range. That's a big improvement for Black, and it certainly justifies attadcing on the tpoint until Black nrns out of ammunition.

Aswe indicatedbefore, Bladrwill attadconthe 2-point until someone makes that point, after which the batde will shift to other fronts. It's often the w e that a point becomes so valuable that both pIayers throw aZI their energies into an all-out struggleto make the key point. Games which hinge on sruggles for key points ate usually the most complex and demanding. Diagram 65: Black on roll

First mission accomplished: BIack has made the 2point. Now a new struggle develops over the &point. IfWhite can malu the 4-point, he'll have what's mild a 1-4 back garne. That's nor one of the strongu back ~~, but it will still be far more dangerous than a simple ace-point game. USlNQ CHECKERS EFFICIENTLY The checker Black placed on the 7-point is a builder for the 4-point, but it's also a slot for the 7 itself. If White makes the 4-point, the 7-point will be the next battleground. Playing 1 117 has accomplished two objectives with one play, as opposed to a play like 1319, which
only provides a builder for the 4point. Top players

White atays out.
BIack 65: 914 1317 Black has won the fight for the $-point, and he now slots the last point he needs to make: the 7-point. Once he makes that, Whiteas chchcckers will h locked in behind six points in a row, and Black can then start moving his badc men around 20.

A p t shot,and suddenly it's a much more interesting middlegame.Although Black is miZL favored to get his back chedter to safety eventually, White is back in the game and can start building a prime of his own. Diagram 68: Black on roll
28. Black41: 1319 24123 Here's an example of how things can get awkwatd quickly. Black of course will keep his 6-prime as long as possible. Note that since the prime keeps four of White's checkerspenned in, White has only 1 1 checkers left to play with. That's not enough to complete a prime of his own, even with optimal placement. Since Black won't move the 12 checkers that make his prime, he has to play the four from the midpoint, leaving a blot there. It will be costly for him ifthis blot gets hit; he'll then have to escape two checken from behind White's position, while having only the spate on the !+point to mwt in case ofan awkwatd number.
29. White 32: 12/15 19121 An excellent play by Snellings. He has several safe plays availableto him. He could try the simple 12/17, or 121 15 17119,or12114 17120.Moftheseplaymarginally increase his building opporruniua at the cost of, at most, a couple of indirect shots. Why did he instead choose to leave a direct shot on the 21-point at a time when Bladis board is so strong?
A PRIME QUICKLY Part of the answer is contained in my comment to a previous play. White just doesn't have very many chedrers left to build a prime of hi own. With four checkers already trapped, he has o d y 11checkers left. That's just enough to build five points with a spare left wer. In ordm to build a prime, White's going to have to tlse hi checkers very efficiently. The most efficient way to use your checkers is to put them righz on the points you want to make.
White's second problem is time. Black has only one checker to escape. Pretry soon he's going to thmw a numberwhich will get him out ofWhite's home board. For aprime to be useful, W h i t e d l havem build it very quickly. Time constraints provide another argument for dotting and covering White just doesn't have the luxury of waiting around to throw p e r k numbers.
Diagram 70: White on roll
The last factor to be considered is the downside of
slotting. What happens ifWhite slots but gets hit?Thc downside, of course, is that White's more likely to get gamrnoned in that case. But notiaethat with four men already back,White is likely to get gamrnoned anyway if he loses this game. The best way for White to avoid ~ game, and the b a t play being gammoned is to w i the for that is Snclling's play, 19121 and 12115. 30. Black 51: 1318 23/22 Playing to the I-point gets one checker out of danger, while moving up to h e 22-point g k two numben m escape (sixes and fours) rather than just one (frves).

WKINa THE R I Q W WlNTs The slight problem with making the 21-point is that it's rally no longer an effective blocking point. A& 17121, Black can leap into the ou&dd with aM fours and sixes, after which White will have to hit or else revert to a straight ace-point game.
Makhgthe 18-point, on the other hand, forms amuch better blockade. Now Black has only sixes to leap, while his other big numbers (fives, fours, and threes) ate stopped. If Black has ro play those numbers on his side of the board, he'll have to give up the 7-point pretry soon. In fact, Black redly has only one spare turn.Amll of54,fbr instance, E o ~ eBlack s to mave the checkers on his 8 and 9-points inm his board. Nem turn, fivcs and fours will make him brak his 7-point.

Although it's slightly safer than the simple 221off (becauseit allows Black to enter immediately and get out of White's hair), safety is not the only consideration. It's wrong because of two other factors: It's not the best play for the gammon.

It's not the best play for the race. Opening the 19-pointgives Black the chance of rolling66 and getung badr in the race. 221off bears offanother checker and makes the race even more secure.

the situation at hand:
(I) Compare the strength of the innet boards. If your inner board is stronger, make a b l d play If his inner board is stronger, make a & play. Here White has the stronger inner board. This argues for a bold play.

BOLD PLAY VERSUS SAFE P U V Some 20 years ago, Paul Magriel, in his great work Backgammon, developed the criteria for deciding ktween a safe play and a bold play, Those criteria were
(2)See who is ahead in the race. Ifyou are behind in the race, make a bold play. Otherwise, make a safe play.
Herethe pip count is White 155, Black 141 after White's play White trails in rhc race, so a bold play is called for.
(3) Who has more men back?If you have more men back, you are inclined ro play boldly. Ifyour opponent has more men back, you ate inclind to play safe.
Here Whire has three men back, while Black has
only one man back (on the bar). This a r g w for
a bold play from White.
All three criteria argue for White to play boldly. The overall sttategic idea is that White, behind in the race with more men back, i s very likely m have to play some sort of holding game or back gamc in order to win unlesshe can quickly build a counteringprime against BlacKs single checker.
Sice he must build this prime quickly, however, he to slot the key points rather than wait to roil them naturally, which is likely to take several more

When playing a back game, it's vital not to get extra checkers stuckin your opponent's inner board. Checkers not needed to holdvitalpoints should keep flowing into the outer boards. This process is called rmirculation, and it's crucial for maintaining good timing.

there's one available.
BACK QAME STRATEQtY First, let's lookat what happens if 1 try to rush my men home as quickly as possible, let's say after 24118*113. White will reenter, perhaps on my 1 or 2-point, and leave his blots on the 10and 1>points. He'll tryto slot the 20-point or the 22-point, building hi b o d quickly.In order to get my checkers on the 14 and 13points home, I'll need to hit one of hi blots, perhaps
Take a look at my spare cherkerson the 6point and 7-
both blots. These checkers w ill enter my board easily, perhaps making a t h d anchor on the Zpoint or the 3-poinr. After that, where will I put my checkers? I'll have to make big stacks on the 6, 7, and gpoina, while perhaps dumping a blot or two on whatever points are left open in my board. Meanwhile, White will build the 20 and 22-points.
point. Right now, those spares are useless to me. I can't use them to make the 4-point or the 5-point since White won't break those points until he can bit a winning shot. Making the 1-point or the 2-point will put them out of play. Suppose I could move those chackers backwards. If I could mwe them back to the 13-point or 15-point, thcy would become builders for the key Bpoint and 10-point. If l could dose those points, I'd haw m t e squeezed! Then there might be a real chance of t r a p ping some White checkers behind my prime and keeping them trapped until his board collapsed. How do J move checkers backward? By recircdaring them, just as White has been doing with his checkers.
So I'm going ro stm dumping those spares onto the
open points in my board. IfWhite hits them when he reenters from the bat, I'll come around the board and take aim at the really imporrant points in the psition - the 9-point and the 10-point.
This strategyhas some built-in risks. I might get some checkers caught in White's home board just as he makes a small block. If I roll awkwardly at that point, I might lose a prime versus prime game. That's a risk I'm willing to mke. I'm going to create an extraordinarilycomplexposition, and I'm expectingto outplay my opponent when that happens. As for the possibilityof bad luck, I'll take my chances.Thais part of the game of backgammon. 25. White 63: Bad3 12/18* White enters, missing the blot on the deuce, and natudly rehits.

It's the only way I can get my checkers recirculated. That's what makes this position different from a normal back game.
In a normal back game, White is trying to be hit and I am trying to avoid hitting. In this position, White is h e r off not hitting or being hit. Howwet, many players in White's position would not realize this.

38. Black 11: Bad24 14/13 11/10*(2) A g m t shot with many ben&a: Hitting anothercheckerwillforceWhite to hit me if he rolls a deuce. Switching from the 11-point to the 10-point brings my points doser together, giving me a stronger blockade. Splitring from the 14-point to the 13-point gives me two builders for the key 9-point, the next blocking point I want to make.
Diagram 10 1: Black on roll 40. Black double to 2. I thought t h s was a v q m n g double and just barely, if at all, a take. My plan has been very successful. I've sent eight checkers back and broken the connection between the two halves ofWhite's position. I've managedto reckollaretwo of the few d d checkers I used to have on the &point and 7-point, and I might still be able to recirculate the other two.And if I make the 9point, my game will be completely uushing.
The v e n t against doubling is that many p l a p s o v e r h a t e the strength of back games and tend to take too o h n .Following that logic, I might be able to
take a roll, improve my psition some more, and still get a rake later on. But it's risky tryingto get too greedy. I've got good chances for a -on this game, so I'm going to get the cube moving now.

One thing I don't want to do at this point is hit any more checkers. Up to now, I've been hitting checkers with the idea of keeping White offbalance and unwordinated, unable to prevent me from making the key outside points. That job is done; I've chided White's position intotwo hatves, withfivecheckersin hi home board and 10 behind my prime.

not able to build any inner-board points. During the hitting bade which followed, White was able m construct a 4-5 holding position.
Rather than play a back game where 'White had excellent timing,Black recirculated some chedrers to build up greater outtield control. m t e was &g to give up key outside connecting points to attempt to build a prime of his own. Eventually Black was able to consolidate control of the outfield and build a prime, trapping 10 o m i t e ' s men.When hi remainingmen were f o r d onto the low points in his board, White loa any serious chances of winning.

White's home b o d pointr 19-24.
Backgammon is full of its own colorful terminology. Here are some terms you wifl want to remember: Advanced Anchor - An anchor on the opponent's 4-
point or 5-point.
Anchor A defensive point in h e opponent's inner board.
Back Game - A defensive position in which the defending side holds two or more points in the opponent's inner board. The best back game points to hold are the 1 and 3, the 2 and 3, and the 2 and 4. The worst back games are the 1 and 4 or the 1 and 5. Any position with three back game points is very swng.
The defensive position on your opponent's side of the b o d . In our diagrams, B i d s back position would be hi points in

Bar Point In our diagrams, B l d s bar-point is the 7point. White's h-point is the 18-point.
Bearoff The section of the game where players bear off checkers from their inner boards in the find race to victory
Builder A checker placed so that it bears on vital points which n d to be made in the future.
Conndvity The arrangement of checkers so that they are in direct range (six pips or fewer) of each other. Connected checkers defend each other and are easily made into points.
Cmwfnrd Gsme In tournament play, the Crawford Game occurs when one side is one point from
victory. In this situation, the doubling cube cannot be used. After the Crawford Game, ifthe match is s d in progress, the cube a n be used
following turn you will have different numbers on the dice to accomplish different objectives. A good offensive maneuver. See also duphtion.
Cmsmwr - The movement of a checker from one quadrant of the board to another, or off the
board h r n the home board. Crossww Count - The total number of crossovers
required to b a r off all checkers. Once all the chackers are in the home board, the crossover count is 15 or less.
Dead Cube Ina tournament match, a cube is said to be deadwhen the player owning the cube has no
reason to wer doubie. For example, a player who is two points from winning the match and who owns a 2-cube will nevcr double, since he mn win the match with the cube at its current level. Direashot-Ashot atacheckersLtorfewerpip away, so that the chedrer can be hit with a single number on the dice.

Diversi6cation Playing your move so that on the
Double To turn the doubling cube one notch, thereby doubling h e value of the game. The player who has been doubled has the oprion of accepting the cube and playing for twice the is opponent the value, or ddining and paying h original stake. Once a player has accepted a double, he "owns"the cube and only he can double again. Downside - What you lose if you take a risk and baddires. See also upside.
Duplication - Playing your mow so that your opponent needs the same numbers on the dice to acmmplish different objectives, thus ensuring that he has fewet rolls working for him. A good defensive maneuver. See also diversification.
Front Position The collection of blockingtattacking points in your own home board. In our diagrams,Black's front position is his points in the area of points 1-8.
k - Six points in a row.
Gammon -Winning the game by bearing offall your checkers before your opponent has borne offany chedrers. The player winning a gammon wins twice the value of the cube.
Longshot -An unlikelybut powerfd roll.The chance ofrollingasingle double, Iike 66, is 35-1against. The chance of rolling a single nondouble, Iike 65, is 17-1 against.
thing P o d To attack by building forward points, constructing a prime, and putting your opponent on the bar.
Losing Your Market - To have both a very solid ahantage and some h a t s which, ifexecuted, will fbrce your opponent to drop a later double.
Home Board -The quadrant of the board to which a player needs to movehis checkersfor thebearoff. In our diagrams, points 1-6 are Black's home board, points 19-24 are White's home board. Also known as the Inner Board.
Midpoint - Black's midpoint i s the 1 I p i n t in our diagams. White's midpoint is the 12-point. A good strategic point to hold in the early game since it provides a lm&g spot for the back checks and controls the outer board
Inner Baard - see Home Board.
Money Gamc- Agame played for money,in which the cube can always be turned, if available. Tournament play differs from money play in that many situations arisewhereaplayer mnt (orshouldnt) turn the cube. Good tournament players must be d e n to these situations.
Knmikaze Play Breaking points in one's own inner board in h o p of getting the checkers recirculatod. A back game strategy.
hint A vital point which conveys a big advantage to whichwer pkyer mn make it first.
W i g Numbers -To play your roll in such away that some numbers on the dice can't be played next turn. A useful way to slow down h e deterioration of your position in a priming battle.
A play that can't be better than an alternative play, no matter what the sequence of dice rolls is. Making a n d o play is the worn possible logical blunder. +
Outer b a d -The points numbered 7-18, which are not part of 4th- side's inner b o d .
Permanentb -An asset which can't go away after a single lucky t h m by the opponent.
Pip Count -The total number of p i p needed to be rolldon thedice to beu offallyour chackers. It's calculated by multiplying the number of a point by the number of checkers on that point, and adding the to& together. At the start of the game, both sides' pip count is 167.
