1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 { Polgar is one of few top GMs who have stuck with the King's Indian Defense, almost exclusively. } 4. e4 d6 5. Nf3 O-O 6. Be2 e5 7. Be3 { 7. O-O Nc6 8. d5 Ne7 (Aronin-Taimanov Var.) has been the most popular, but 7. d5 (Petrosian Var.) and 7. Be3 (Gligoric Var.) are also played regularly. Black doesn't want to let Be3 remain so actively placed, where it supports Pd4, so Black usually threatens to capture it by ...Ng4. It's important for Black to force a simplification of some kind in the central pawn formation, so as to know how best to develop the other pieces. } 7... Ng4 8. Bg5 f6 9. Bh4 { White is trying to keep the pressure on and to avoid committal pawn moves. Black has to play this part forcefully. } ( 9. Bd2 ) 9... g5 $5 ( 9... c6 10. dxe5 dxe5 11. Qxd8 Rxd8 12. h3 Nh6 { is still about equal, but Bh4 isn't so well placed when the center is now open. And, White can't force things open on the king-side by Nxe5. } 13. Nxe5 $2 g5 $17 ) 10. Bg3 { White might be threatening Nxg5 to force the position open (though it wins no material) . } 10... Nh6 11. h3 $6 { Although this gives an escape square for Bg3 it seriously weakens the king-side, where White's king might soon be residing. } ( 11. h4 { chopping away at Black's dark-square pawns in order to give Bg3 some air has the cost of endangering Ke1. Where will it live for the duration? } ) 11... Nc6 { Black wants to trade at d4 and then use ...f6-f5 to uncover another threat before playing ...f5-f4 to mash Bg3. } 12. dxe5 fxe5 { Black sees reason to allow a queen trade; especially when ...g5-g4 might still allow the king-side to open nicely for Black's pieces. The only cost is in leaving d5 to White. } 13. Qd2 Nf7 14. Nh2 Nd4 { White notices d4 is weak and he hasn't got Be3 or Nf3 to challenge it. } 15. Bg4 Nh8 $1 { I haven't seen this maneuver since a game of Bobby Fischer's. It's maneuvering toward f4 or h4. It takes time for knights to get to their ideal squares, whereas queens, rooks and bishops can often arrive in just a couple of moves. } 16. Nf1 Ng6 17. Ne3 Nf4 18. f3 c6 19. Bxc8 Rxc8 { Black is well placed on the queen-side to meet O-O-O with ...b7-b5, so White's monarch has no perfectly safe square. } 20. h4 b5 21. cxb5 cxb5 22. Bxf4 exf4 $1 { Unblocking Bg7 to take aim at White's queen-side is another way to dissuade White from O-O-O. However, on the king-side Black's pawns are advanced and might force an opening in case of O-O. } 23. Ned5 a5 24. Rc1 g4 { White isn't castling queen-side, so Black wastes no time in continuing the king-side offensive. White's "strong" central position is meaningless and Black's Bg7 with Nd4 is just as useful as Nd5. } 25. fxg4 f3 26. Kd1 { The lack of a safe residence for White's king is most evident now. } ( 26. g3 f2+ 27. Kf1 b4 28. Nd1 Qe8 29. Nf4 Qb5+ 30. Kg2 Nf3 31. Qe2 Qxe2 32. Nxe2 Ng1 33. Rxg1 fxg1=Q+ 34. Kxg1 Rxc1 35. Nxc1 Re8 $17 ) 26... b4 27. Na4 Rxc1+ 28. Kxc1 Ne2+ { a simple tactical finish } 29. Kb1 fxg2 { Pg2 will cost White a piece. } 0-1
