WHAT IS "POWER PLAY!" ?? The modern amateur chessplayer has been bombarded with thousands of examples of chess literature aimed at I nstructing t h e stude nt in ways to conduct the opening and middlegame in chess. How many of us have not rushed to the bookstore to purchase the latest "System against the ... " or "Encyclopedia of..." or "Complete Repertoire against..." in our quest to improve our knowledge and (hopefully) our results, only to find that we must wade through a mass of variations and complete games, a ti m e - c o n s u m i n g a n d i nti m i d a t i n g method of study that often defeats its own purpose. While we at ChessBase University acknowledge the importance of the traditional literature, we hope to tackle the two most fundamental and im portant problems that the chess amateur faces when he reaches the critical transition between the "opening" and the "middlegame" ...

How do I get there??

What do I do after I'm there?? The concept of "Power Play!" is that chess openings and the middlegames derived from them can be broken down into a number of critical positions, and that study of these positions in an interactive playing environment will confer on students a deeper, more resilient understanding of the problems that confront them on the chessboard. These " Power Play! " positions have been carefully selected from thousands of master games and are the key element of this book's structure. As in ice hockey where "Power Play" implies a man or

more superiority on the ice, "Power Play! " adds a serious weapon to the chess arsenal of the prepared student. This "Power Play!" book was originally developed In electronic format to be u s e d wit h C h e s s B a s e U S A ' s maste r-st r e n g t h p l a y i n g p r o g r a m KnightStalker (or Fritz), and that still remains the most convenient, efficient way to apply the Power Play! method. But "Power Play!" can be used effectively by a n yo n e w h o wants t o rea l l y understand chess, whether you have access to any one of a number of chessplaying programs and dedicated machines, to an avid sparring partner at t h e l o c a l c l u b, o r t h e s i m p l e, o ld -fas h i o n e d expedient of p i e c e shuffling in the convenience of your study. Either way, "Power Play!" will make you a stronger, better informed player. STRUCTURE OF THE POWER PLAY! BOOK-ON-DISK

If you own an MS-DOS compatible computer, you might want to consid6r the additional investment in ChessBase U n iversity a nd t h e " P owe r P l a y !" books-on-disk series. In addition to the wealth of useful information provided to you in this book, the disk provides a set of computer-specific tools to make your study task even easier. "Power Play!" disks include: 1 . Document files which contain material that can be viewed in Hypertext. The Hypertext will present an overview of each of the "Power Play! " positions from the opening under study, discussing

The Archangel! (CBU 250pp) White's and Black's plans and allowing access to the critical position in the game files. Additionally, you will find references to "Key Games" in the game file, also accessible from Hypertext. 2. A Chess Base games file (.cbf) typically containing an Index, 30-50 "Power Play!" positions and 40-80 "Key Games" lightly annotated with study material related to the critical positions. 3. Comprehensive "Opening Book(s)" (.fbk) which when utilized by Fritz or KnightStalker, allow the student to practice using his n ew knowledge a g a i n st a wel l -armed and al ways available adversary. We warn you that we have DE LI BE RATE LY inco rporated some inferior l ines and blunders Into these "Opening Books". By allowing KnightStalker the option of playing "weakly" we have provided an additional test for your tactical ale rt ness and

lV

opportunism. Some of the forthcoming "Power Play! " books will require the use of more than one "Opening Book" - on such occasions, you will be provided with instructions on how to engage the necessary "book" before doing battle. 4. A rudimentary "Opening Key" that will speed the process of searching for specific entries in the games file when viewing material from within Access or ChessBase. If you're Interested in "Power Play!

TRAINING TIPS After reviewing t h e " P ower Play! " instructional material on each position and and examining some of the relevant "Key Games", you should try out what you have learned against any available sparring partner - computers are ideal for the intricate trial-and-error of training games, but people make good training partners too. The important thing is to go over your games once they're finished, check them against the principles you've studied in the book, and keep a record of what you've learned. This is the key ingredient of the "Power Play! " learning experience. This way you will build a private log of your progress and amass a wealth of new material unique to you, eve n t u a l l y d evel o p i n g y o u r own repertoire of critical positions.

Under test conditions, one member of the "Power Play!" editorial board has played over 200 games(!) against Fritz using the "Power Play! " method. During Nov-Dec 1 992, IGM Ran Henley tested the prototype of CBU250pp and as a result discovered a considerable number of theoretical novelties. This technique is now a cornerstone in Henley's training methodology. Naturally, you should play these critical positions with both white and black to d ee pe n your und erstanding of the opening. As new titles in this series appear, you will be able to assemble an opening!middlegame repertoire that has been t horoughly tested - and has thoroughly tested you!- before you risk it in live combat.

About the Authors by Don Maddox Ron Henley

Born: 1 2/5/1 956 Houston, Texas Grandmaster:

1 982

The most important thing to remember is that Ron Henley is a Texan. I'm almost tempted to leave it at that. lt explains a lot. But Ron Henley is also an accomplished businessman, a member of the American Stock Exchange, and one of America's finest chessplayers, the only American ever selected to serve as second to a S o v i et p l a y e r d u ri n g a World Championship match, assisting former World Champion Anatoly Karpov during his 1 990 title bout with Garry Kasparov. Ron earned his Grandmaster title in S u r a k a rta - D e n pasar 1 982, an I nd o ne s i a n s u p e r - G r a n d master tournament in which he scored 1 7.5 of 25 to tie with International G randmaster Waiter Browne for a surprise first place f i n i s h . W i t h s u c h recog n iz e d i n t e rnational s u pe rstars as La rry Christiansen, Tony Miles, Vlastimil Hort and Zoltan Ribli slated to play, little attention was directed to an unheralded I nternational Master from Texas before the tournament. "Confidence is the key," he told me years later. "Confidence and preparation. I knew I had a chance. I had done my homework, and I was ready. Everyone w a s s u r p ri s e d w h e n I w o n t h e tournament except me. Of course, you can't know you ' re goi n g to win a tournament, but it's important to believe you have a chance."

Today, Ron is one of fewer than 40 International Grandmasters living in the U.S. He started playing chess in 1 972, one of a generation of talented young players to emerge in America during the d ecad e fol l ow i n g B o b by Fischer' s spectacular world championship bid. He was 16 at the time. Ten years later he was a Grandmaster himself. Paul Hodges

Born: 1 2/6/1 957 Cardiff, Wales (UK) National Postal Master:

Paul Hodges was coming off a seven year hiatus as a chessplayer when I met him in 1 99 1 . I n the i nterim he had completed a Doctorate at the University of Wales and his Post-Doctoral work at the University of Montreal in Canada, and established himself as a Senior Research Chemist for Merck Labs in New Jersey. A brutal perfectionist as a postal player and a veritable caveman over the board, Paul quickly earned a spot on a small ChessBase USA team - as a friend, as a sparring partner, and as a test bed for new ChessBase University ideas and products. Ron and Paul hit it off immediately. I mpressed by Paul's analytical skills away from the board, Ron was equally amazed by h i s spa rri ng part n e r ' s reckless style across the board. "Paul's in trouble now," he would joke, rolling his eyes when the position became blocked. "There are no pawns left to sacrifice."

A v e ry s u c c e s s f u l i nt e rn a t i o na l correspondence player before entering grad uate school In 1 984, Paul has become o n e of America' s leading correspondence players and is one of t h e worl d ' s most exp e r i e nced ChessBase users. H i s years as a s c h o l a r a n d a correspondence chessplayer make him uniquely qualified to teach chess to new and experienced players. He knows how to put his finger on the critical position that makes a variation "tick" and how to prepare for it over the board or through the mail; he knows how to explain what's going on in clear, simple English; and he knows how to make sure that loose ends are tied up before you risk a line in live combat.

Forward " b oo k - o n -d i s k " f o r C h e ss B a s e U n iversity, " M u rd e r o n t h e L o n g Diagonal: The Archangel Variation of the Ruy Lopez."

The idea for "Power Play!" emerged from a s e r i e s of m e e t i n g s betwe e n I nternational Grandmaster Ron Henley, Correspondence Masters Jon Edwards and Paul Hodges, and myself. Our goal was to combine Ran's experience as a player and world-class trainer with the research and analytical skills of top level correspondence players and my years as a chess coach and teacher to produce a new kind of training material.

"What I'd like," said Ron, "is a convenient way to use KnightStalker as a training tool to practice my openings. The most important thing a writer can do for a player, in my opinion, is to point out what's important and help cut through the maze of material that's available."

A l l of u s , f r o m G ra n d master t o G rand patzer, agreed that traditional opening manuals are fine as reference books, but d o l ittle to h el p players actually understand an opening. We sat down to compare notes.

We sat down that very evening and carved out the prototype for this first "Power Play! " project, and Ron and Paul set out to test the idea. More than two hundred games later, Henley declared the experiment a roaring success:

W h at w e f o u n d w a s a sta rtl i n g commonality, at different levels, i n the way we each approached our own study of openings. In his own preparation, Ron focused on critical positions, making sure he thoroughly understood a variety of plans and ideas before adding a line to his repertoire. In postal chess, Jon and Paul made a point of identifying target positions and thoroughly preparing for the kind of unresolved tension necessary to create winning chances in the test t u b e at mos p h e re of t o p-f l i g ht correspondence chess. As a teacher working with new students and high school kids, I had always found that concentrating on a few key ideas and p l a n s from key positi ons was the quickest way to break my kids of the bad habit of trying to play good chess by rote.

"This is the way chess should be studied. The point is not to smother yourself in reams of analysis and variations, but to build up experience position by position until you thoroughly understand what's going on at the board. The computer makes it even easi e r a n d m o r e convenient, but I wish someone had done this for me 20 years ago, even in book form. lt would have saved me 1 0 years hard labor."

The most amazing thing of all is that what 1 wanted for my kids - a well-defined repertoire of carefully selected critical positions in an opening - was exactly what Ron wanted for his own training. We were just finishing work on a repertoire

In the interim, I tested this new approach on my students. To my delight and amazement, I fou nd that the same material Ron was finding useful at the GM-level helped cut the learning curve in half for my beginners. In fact, at an intermediate level, I found the same material useful in my own study. The d ifference between one student and another l i es si mply in the l evel of guidance required to direct their study. A grandmaster's not much interested in explanations, a beginner wants help understanding why a move is interesting

tx

The Archangel! (CBU 250pp)

and what to think about in a given position. No matter how you study - at home with your computer or at the club with your friends - you're going to find "Power Play!" the ultimate tool for improving your chess. The Archangel Variation of the Ruy Lopez lends itself beautifully to "Power Play!" treatment, with clear, forceful tactical lines and strategic ideas. Little known and even less understood at the club level, this variation draws a great deal of the venom from the dreaded "Spanish Torture." We hope you enjoy this book as much as we enjoyed putting it together. As a team, we take pride in the launch of a series of chess books designed to be USED by chessplayers of all levels. Good luck - and good chess! Don Maddox Manasquan 1 993

Acknowledgments

No project like this is ever executed in a vac uum. Power Pl ay! i s especially dependent on the support and good will of Paul's wife Josee Audet. Thanks is also d u e t h e C h e s s B a s e USA staff i n Maryland - Sharon Richmond, Steve Lopez and Ran Maddox. But perhaps the most important thank you of all goes to our mothers - M uriel Hedges and Belva Maddox - without whom Power Play! might still be a shimmering light dancing at night on a moonlit pond in Wales. And we don't want to forget Sister Syra who quieted a restless Welsh boy by sending him to a cornerwith a chessboard almost 30 years ago.

The Archangel! (CBU 250pp)

INTRODUCTION to POWER PLAY! CBU250pp The basic position of the Archangel Variation of the Ruy Lopez arises after the sequence of moves: 1 .e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 b5 6.Bb3 Bb7

The Archangel Variation is one of Black's sharpest responses to 1 .e4, leading to a va riety of strat e g ical l y c o m p l ex continuations largely d ependent on W h it e ' s c h o i c e of 7th move. T h e Archangel is a firm favorite o f such uncompromising players such as Alexei Shirov, Alexander Belyavsky, Vladimir Malaniuk and Ad rian M i khalchisin studying these player's games is a worthwhile exercise in its own right. This book examines the Archangel on a position- by-position basis in all of the main continuations from White's 7th move, and is aimed at giving the student a thorough grounding in the positional and tactical motifs found in this opening system from both the Black and White sides of the chessboard. Ultimately, the student should be able to make an

informed and confident decision as to whether the Archangel Variation should become a part of his everyday opening repertoire. This book contains 48 critical "Power Play! " positions from the Archangel Variation, illustrated by 62 Key Games or G a m e F r a g m e nts, many of w h i c h contain a n a l ytical c o m m e n t s a n d sub-variations. You can also enroll i n GM " G ra n d m a s t e r Ron Henley's Gymnasium" where Henley explains his training technique, illustrated with 4 annotated games played against Fritz in the same sub-line. As a bonus, we include 7 add itional games played between Fritz and Henley (annotated) from various lines in the Archangel. These latter games were played during the Nov-Dec 1 992 test of the CBU250pp Power Play! prototype. Is it possible to distill a complex system such as the Archangel into 48 critical positions and obtain a complete and exhaustive survey? Considerin g the wealth of material available to draw on, probably not. But an encyclopedic coverage of this fascinating opening is not our objective in this book - rather we seek to equip you with enough basic knowledge and understanding of the strategical and tactical nuances of the Archangel that you can confidently tackle the opening from either sid.e--over. 1 the board. An overview is provided of each "Power Play!" position, introducing the student to the basic concepts underlying each position. After this convenient review, we provide one or more practical examples in the illustrative games to prepare you for live play.

Obviously there is risk entailed with this continuation as the light squares around black's king are severely weakened, but sooner or later black must break the pin.

This continuation is very risky for black. White has a mobile pawn-center and black has not dealt with the pin on the d8-h4 diagonal. Should black now try a ... g7-g5 pin-breaking push, he invites a dangerous sacrifice on gS. ( 1 8)
