Preface The Polar Bear is a system for players who like interesting and original positions without being too concerned about proving a theoretical advantage. In many of the variations the positional themes and plans are of more importance than actual move orders. Our system starts after 1.f4 (the Bird opening) and then fianchetto of the Kings, Bishop. A mirror image of the Leningrad Dutch. The system is a hybrid combination of the strategically complex King's Indian and Dutch defences. By playing the Polar Bear, we make it difficult for Black to play for a flat equality. We want a potent, fighting game with a "full board". I do not understand why the Dutch defence 1.d4, f5 is considered an aggressive opening, but the Bird 1.f4, d5 not. It doesn’t seem logical. I will let the veracities speak for themselves and show you a strong and fascinating system. I have spent 15 years developing the Polar Bear System. I know it inside out. However I have to warn you: The Polar Bear System is difficult to handle! Indeed I have turned every stone in the system and lost many games doing so. Since there is no theory of importance, I had to work hard. I read everything about the Dutch defence and used the ideas with reversed colours. Therefore the theory in this book, was mainly created through my own

games and analysis. I have played thousands of games online, trying to discover the very essences of the system. Many of the games were of poor quality, so I had to select the cream. And turn the cream into a repertoire book. Omitting lines in which I do not believe. The project turned out to be too substantial for one book, so I had to split it up in two books. I would like to thank my partner Arora Hronn Skuladottir,for helping me turn the Polar Bear System into a book. She is a multitasker! Computer typesetting, creating the cover, proof reading, photos and final preparation. Without her help, it would have been difficult. Nevertheless here is Volume 1 of the Polar Bear System, with a full covering of the main lines in 1.f4, d5.

Introduction After the opening moves 1.f4 d5 2.Nf3 g6 3.g3 Bg7 4.Bg2 Nf6 5.0-0 0-0 6.d3 c5 7.c3 Nc6 8.Na3 we reach our main line of the Polar Bear system.

White’s strategy. The advance e2-e4. This is the idea behind the system. We want to expand in the centre. After dxe4,dxe4 we have an advantages type position. We do not mind to exchanging Queens.(See Fischer game). If black keep the tension, then we expand with e4-e5 again, with an advantages type position.(See Nigel Davies handle the endgame and I the attack). If Black answer e2-e4 with e7-e5,then the advance f4-f5 potentially opens the f-file and frees the Bc1 to a full diagonal. This trust may be supported by… Nh4 or

6

even played as an outright sacrifice. We only answer e7-e5 with f4xe5, if we gain an advantage or see ourselves forced to do it! We do not allow Black to create a bind with d5-d4. Our backward pawn on e2 must move to e4. One bad backward pawn can destroy the whole army. Our trouble piece is Bc1, as it can be difficult to find a good job for it. The diagonal a7-g1 has been weaken. Be careful. Do not allow tactics on the diagonal a7-g1! What are Black’s plans? To create a bind with d5 -d4 and open the e-file and put pressure on the backward e2- pawn. Black would also like to expand on the Queenside. We cannot prevent the Q-side expansion, so we ignore it by imposing our own expansion, but in the centre! Let us talk about the Queen. You must only put her on e1 if forced, or if it is good move. The plan with Qe1, h3-g4 and Qh4 is too slow. Been there, done that. The Queen belongs on c2 or a4 to support the push e2-e4. The c3 pawn does a great job to restrict Nc6 and Bg7 and opens the diagonal d1-a4 for the Queen! The square d3 has been weaken in the process. The strong and the weak produce the one! (All this is covered in the study material) Black has played many different moves at this point. We will examine these, in turn:

7

A) 8 ... d4 We play 9. e4! dxe3 After 9...e5 we acquire a great game with 10.Nc4 or 10.cxd4, followed by Nc4 and 9...dxc3 10.bxc3, which leaves White with the better centre. 10. Bxe3 Because of White´s time advantage, Black is under pressure. He has to protect the c5 pawn, if 10... Bf5 then 11.Re1 Qxd3 12.Bxc5 with joy. b6 11.Ne5! Nxe5 We do not capture on a8. It is not good. 12.fxe5 and then after Nd5 13.Bf2! followed with 14.d4! is strong. E.g. 13...Bxe5? 14.d4 cxd4 15.Bxd4 and Black has a hard time to survive.

B) 8 ... Re8 9. Nh4! A move typical for the Polar Bear tactics. We are ready for a Kingside attack! We ignore Black`s plan by imposing our own! Now 9...e5 is playing into our hands.Nh4 has also made e4 possible.

C) 8 ... b6 Black protects the vulnerable QBP and prepares to fianchetto his second Bishop to neutralize our Bg2. 9.Qa4! Designed to support e2-e4 from the side. My gain with this move is good.

8

D) 8 ... Bg4 Black might play BxN followed by e7-e5 or Qd7 and Bh3. 9. Qc2! Here the Queen is well placed and supports the thematic e2-e4 move.

E) 8 ... Bf5 If left undisturbed, the Bishop prevents e4. However, the Bishop is a target that White can exploit for his attack.

F) 8 ... Qc7 This is another way in which Black can support e7-e5. The downside of 8...Qc7 is that the Queen may be attacked by a timely Nb5 or Bf4.

G) 8 ... a6 Is too slow, and if the move b5-b4 is made later on, then Black doesn’t have the a6 square for Bc8.

H) 8 ... Rb8 Intending an advance of the QNP to exploit White´s backward Q-side development and keeping the a6 square free for Ba6. 9.Ne5! Here we have no time to prepare e2e4 with Qc2.

9

We start by looking at three typical Polar Bear System (PBS) games. For understanding the type positions.

10

GM BOBBY FISCHER – IM DURAO JOAQUIM 1. e4 e6 2.d3 c5 3.Nf3 Nc6 4.g3 g6 5.Bg2 Bg7 6.0-0 Nge7 7.c3 0-0 8.d4 d6 9.dxc5 dxc5 10.Qe2 b6 11.e5 a5 12.Re1 Ba6 13.Qe4 Ra7 14.Nbd2 Bd3 15.Qh4 Nd5 16.Qxd8 Rxd8

This type position appears often in the PBS. It looks level, but White has the better pawn structure. Slowly Joaquim is outplayed by Fischer.17.a4 Rad7 18.Bf1 Bxf1? 19.Kxf1 Nde7 20.Nc4 Nc8 21.Bg5+/= N6e7 22.Nfd2 h6 23.Bxe7! Rxe7 23...Nxe7 24.Ne4 Rb7 25.Ra3+/=. (diagram on the right). 24.Ra3 Rc7 25.Rb3 Rc6 26.Ne4 Bf8 27.Ke2 Be7 28.f4 Kf8 29.g4 Ke8 30.Rf1 Rd5 31.Rf3 Rd8? 31...Kf8!?+/- 32.Rh3+Bf8 32...Kf8 33.Rxh6 Kg7 34.g5+- 33.Nxa5!

HD – FM ROBERT LAGERMAN REYKJAVIK 1.f4 d5 2.Nf3 g6 3.g3 Bg7 4.Bg2 Nf6 5.0-0 c5 6.d3 b6 7.c3 0-0 8.e4 Bb7 9.e5 Ne8 10.d4 Nc6 11.Be3 cxd4 12.cxd4 with the centre closed Black has difficulty bringing Q-side forces to the defence of his Kinghouse. White´s pieces coordinate quite well for a simple attacking machine. e6 13.Nc3 Rc8 14.Rc1 Na5 15.b3 Nc7 16.Rf2 Re8 17.g4+/Bf8 18.f5 Qe7

19. fxg6? Too early. Better is 19.Ng5! fxg6 20.Ng5 White has a King attack. Bh6 21.Qd2 Rf8 22.Rxf8+ Rxf8 23.Ne2 Nb5 24.Nf3 Bxe3+ 25.Qxe3 Rc8 26.Bf1 Rxc1 27.Qxc1 Qa3 28.Qh6 When you decide to attack, keep calm with a strong spirit. Nc7 29.Ng5, Qe7 30.Nf4 Nc6 31.Bd3 Nxd4? 31...Nd8+/- 32.Nh5! Doomsday Ne8?? Terrible, but the game is lost in any case 33.Bxg6! (diagram on the right). A devastating blow. E.g. hxg6 34.Qxg6+ Kf8 35.Qh6+ Kg8 36.Nf6+ Nxf6 37.exf6 Nf3+ 38.Kh1 1-0

14...Na5 15.Nc3 Qd7 16.Rc1 Ba6 17.b3 Rc7 18.Qd2 Rfc8 19.Bf1! Nigel exchanges Blacks active pieces and transfer the space advantage into the endgame Bxf1 20.Rxf1 Bf8 21.g4 Kh8 22.Bh4 Black has a cramped position Ng8 23.Ne2 Rxc1 24.Rxc1 Rxc1+ 25.Qxc1 Be7 26.Bxe7 Nxe7 27.Kf2 Kg7 28.Ng3 h6 29.Qd2 Nac6 30.h4 Ng8 31.h5 White prepares the advance f5. Nce7 32.Qc2 Qc6 33.Qxc6 Nxc6 34.f5 gxf5 35.gxf5+/- f6 36.fxe6 Nge7 37.Ke3+- (diagram on the right). 37...Nd8 38.Nh4 fxe5 39.dxe5 Nxe6 40.Nhf5+ Nxf5+ 41.Nxf5+ Kh7 42.b4 a6 43.a4+- a5 44.b5 Nc5 44...d4+ is the last straw. 45.Kd4 Nxa4 46.e6 Kg8 47.Nxh6+ Kf8 48.Nf5 Nc5 49.Kxd5+- 49.Kxd5 a4 50.h6 Nxe6 51.Kxe6+- 1-0 A long-scale strategy.

Playing 1.f4 is all about type positions. Bent Larsen (1935-2010)

I have polished and cleaned of all harmful moves to clear a safe path. Depending on the circumstances, the PBS should be played hard, flexible, smooth or patiently. It is strong and resilient but in order to win with it something has to be given to us: a square, a pawn or a tempo. I had to create this system with my own games played on the internet. Theory did not exist or it was unusable. I decided to use and present the Internet games anonymous. It’s a new concept to use own games played on the Internet for a book. I love to leave main theory to discover old underestimated openings. Develop the insights to playable systems and win. I want to thank all of my opponents for great fights and for beating me up when I was using wrong manoeuvres. I used those lessons to get insights. I hope I gave some of you similar lessons. The coin has two sides. The process took me 15 years. A long journey but joyful. My intention was to write only one book but the material was extended. So I had to split it up in two books.

14

Every game and every move has been checked by the chess programs Stockfish and Fritz 13. It will not be easy for the reader to find a tactical mistake in the text. It is on purpose I have chosen to comment the games with short text. Boiling the material down and letting the games speak for themselves. The content of the book is compressed. Therefore I recommend that it should be read from page one. The suggestions are for serious club players but also professionals can get inspiration. There are many pearls to be discovered. It was not an easy task. Did I accomplish my goal? It´s for the reader to judge.

Set ups with Nh6

1.f4 d5 2.Nf3 g6 3.g3 Bg7 4.Bg2 Nh6

Nh6 without c5 Nh6 with c5 Why Nh6 instead of Nf6? To leave Bg7 with influence, and to use f5-square for Nh6. To increase the pressure on the square e3.It can then be entrenched with h7-h5. Black has two different ways of playing this system. With or without the pawn move c7- c5. Black usually delays castling for a few moves. Slow is c7-c6 and Qd8b6 with a dual attack on b2 while eying the a7-g1 diagonal. White answer d2-d3,c2-c3 , e2-e4, Qd1.e2 and Bc1-e3 (see HD-Langgaard). A Nh6-g4 planning Ng4-e3 or Ng4-f2 transfer to the c7c6 and Ng8-f6 system and will be covered in volume II.

84

Nh6 in connection with b7-b6 and Bc8-b7 (HD-GM Nunn) Nh6, Nc6 and not moving the c7 pawn covered in vol.II. A setup with c7-c5 is quieter. Black tries to create a bind with d5-d4. We don’t allow it and answer d5-d4 with e2-e4. (See the study material) The centre expansion e2-e4 enables us to meet every challenge and to establish harmony in our army. 1.f4 d5 2.Nf3 g6 3.g3 Bg7 4.Bg2 Nh6 5.d3 c6 5...0-0 6.c3 b6 7.0-0 Bb7 8.Na3 Nbd7 9.Qc2 and e2-e4 6.c3 Qb6 7.e4! dxe4 8.dxe4 0-0 9.Qe2 and Be3 with a stable centre. 1.f4 d5 2.Nf3 g6 3.g3 Bg7 4.Bg2 c5 or 4...Nh6 5.d3 d4 6.0-0 Nf5 7.c3 c5 8.e4! dxe3 9.Na3 Nc6 10.Re1 0-0 11.Bxe3 Nxe3 12.Rxe3 with a type position 5.0-0 Nc6 6.d3 d4 7.c3 Nh6 8.e4! dxe3 9.Bxe3 with initiative.

1. f4 is just a normal move. Bent Larsen (1935 – 2010)

Hunting with 1.f4 A real PBS player never attacks premature. He is always in control. He never runs away from any kind of challenge, but does not try to suppress or control an opponent unnaturally. He ignores the opponent`s threat by imposing his own treat. He cast of limiting thoughts and fights in a vibrant and joyful manner. He plays with a feeling of constantly crushing the Black position.

In Conclusion… This last part is intended to tie up a few loose ends. 1. f2-f4 is the Bird opening. Played by Henry Bird in 1873.This got him out of the books and created unique positions. The Polar bear system is 1.f2-f4 followed by the fianchetto of the Kingside Bishop. My intention was to write only one book but the material was extended, so I had to split it up in two or more books. I did my best and I hope you will continue the exploration of the system in upcoming books. Where I will finish 1.f4, d5 and continue with 1.f4, e5 the From´s gambit. Finally, I would like to wish all readers joy and success with the Polar Bear System. GM Henrik Danielsen www.polarbearsystem.com
