1. e4 c5 2. Nc3 Nc6 3. g3 g6 4. Bg2 Bg7 5. d3 Nf6 6. f4 White is playing very aggressively, and this may come back to haunt him. The kingside is open and does not provide a safe haven for the king, and castling queenside may be reckless with Black being able to open the c file. 6... d6 7. Nf3 O-O 8. O-O e6 9. h3 Bd7 10. Be3 Rc8 11. g4 Qb6 12. Rb1 a6 12... Nd4 is a good move here, and for the next few moves as well. 13. Nh4 White ignores any threats on the queenside to build an attack on the Black king. 13... Qd8 14. Qe1 Nd4 15. Rc1 b5 16. f5 White can take a moment to further prepare for the kingside thrust while also threatening on d4 with 16. Qf2 16... exf5 17. gxf5 Qe7 18. Nd1 b4 19. c3 bxc3 20. bxc3 Nc6 21. fxg6 fxg6 22. Nf3 Ne5 22... c4! is very disruptive to White's position, because it weakens White's hold on e4 and grabs control of the center, spoiling White's attack. 23. Nxe5 Qxe5 23... dxe5 is better, since the queen cannot be held on e5, and it removes Black's backwards d pawn and creates outpost an on f4 and immobilizes White's center pawns, while making it easier to hit the white d pawn on the half open file. This is one of those cases where the positive benefits of the isolated pawn outweighs it's detractors. 24. Bf4 Qe7 24... Qe6 gives the queen more scope and gains a tempo by hitting the unsupported a pawn. 25. Ne3 Bc6 26. Qh4 26. Nc4 gives White attacking prospects. The queen just doesn't have any targets on h4. 26... Qe6 27. c4 Nh5 28. Bh2 Bf6 28... Bd4 is more restricting, but just falls short of winning material. 29. Qg4 Qxg4 30. hxg4 At this point, the game is almost even, with only a minor edge to Black, but the situation is rich and full of complications. But regrettably, the score ends here due to time trouble. White went on to win, but there is no record of how this interesting game continued. 1-0

1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. d4 exd4 5. Nxd4 Bb4 6. Nxc6 bxc6 7. Bd3 d5 8. exd5 cxd5 9. O-O O-O 10. Bg5 c6 11. Na4 All of this has been the book line of the Four Knights Defense, Scotch Variation. At this point there are two primary continuations 11. Ne2 h6 12. Bh4 Bg4 13. c3 Bd6 14. Qa4 Bd7 which appears to be, as the book says, even. Or 11. Qf3 Bd6 (11... Bxc3 12. bxc3 h6 13. Bf4 is supposed to favor White, possibly because of the bishop pair and the potential for a kingside attack, but I don't see it, given that the White pawn structure is so disrupted and Black seems to have adequate defensive resources.) 12. Bxf6 Qxf6 13. Qxf6 gxf6 Again, the book says this is an even position, but I don't see it. Granted, Black has the bishop pair, but again, the Black pawn structure is a shambles, much like in the preceding line for White. Apparently, Aleksanda agrees, since as the game progressed he gave Black the bishop pair with the damaged pawn structure. 11... Be6 12. Qf3 h6 13. Bxf6 Qxf6 14. Qxf6 gxf6 15. Rac1 Rab8 16. c4 Bd6 17. cxd5 Bxd5 18. b3 Rfe8 19. Rfd1 Re5 20. Bf1 If White is concerned about a coordinated attack against the g2 square, wouldn't 20. Nc3 have been a better way of dealing with it? As is, unshielding the rook on d1 doesn't seem to help much either. 20... Rbe8 21. Nc3 Ba3 22. Nxd5 Rxd5 23. Rxd5 cxd5 24. Rc7 a5 24... Re7 might have made for a more tenacious defense, as White will most likely avoid trading rooks since the bishops are of opposite color. But it's close, and so hard to make the call. 25. Rd7 Re5 26. g3 Bc5 27. Kg2 Kf8 27... d4 so the pawn could be supported by the bishop would have been better. Now Black begins to let the draw slip away. 28. f4 Ke8? Black wants to preserve the d pawn, but that is simply not possible. The attack on the rook must be addressed directly, not with a counterthreat, because the Black pieces are not mutually supporting. The rook should be kept on the e file, but will be lost if it attempts to move sideways to hold the pawn. 29. Bb5? White can win material immediately, without waiting for Black to make an error, by 29. Rc7 Bb6 30. Bb5+ to add coverage of the e8 square 30... Kf8 31. Rc8+ Ke7 32. fxe5 29... Re3 Black misses his last chance to minimize his losses with 29... Re2+ 30. Kh3 Rc2 30. Rc7+ Kf8 31. Rxc5 d4 32. Rd5 Re1 33. Rxd4 This is a game that got away from Guy. It's not recorded if a draw was ever offered, but such an offer was certainly justified between moves twenty and twenty-five. 1-0

1. e4 d6 2. d4 Nf6 3. Nc3 g6 4. Nf3 Bg7 5. Be2 O-O 6. O-O c6 7. h3 b5 This has been a Classical Variation of the Pirc Defense until this point. The book move is 7... Qc7 after which White has a few options. 8. a3 Nbd7 9. e5 dxe5 10. dxe5 Ne8 11. e6 White sacrifices a pawn to disrupt Black's position. While the idea is good, it's execution is premature. White should complete his development, possibly doubling rooks or rook and queen in the center, before releasing the tension. Black should not be able to marshal his defensive forces as quickly as White can build for the attack. 11... fxe6 12. Ng5 Nc7 13. Bg4 Nf6 14. Be3 h6 Black should trade off the queens on d1, possibly the bishop for knight on g4 if White doesn't move the bishop in retaking the queen, and deploy a knight to d5 to either improve his own pawn structure or damage White's in compensation. Then the extra pawn he has will become a valuable asset. 15. Nge4 Nxe4 16. Nxe4 h5 16... Bxb2? 17. Bxh6 Bxa1 18. Qxa1! Rf7 19. Rd1 with good play. 17. Bf3 Qxd1 18. Raxd1 Bxb2 Black is now two pawns ahead, but still lags in development and has a pawn structure somewhat worse than White's, but overall has much the better game. 19. Rd3 Bg7 20. Bc5 Nd5 21. Ng5 b4 The pawn in momentarily immune thanks to the threat of ... Ba6 skewering the rooks. 22. Re1 a5 23. g3 White avoids the trap 23. Nxe6 Bxe6 24. Rxe6 Nf4 but now such a maneuver is possible. 23... Bc3 23... Ba6 is also worth consideration here, though it is very complicated as White can unbalance the position by giving up the rook to take other material. Perhaps Black was hoping White would place the attacked rook on d1, after which Ba6 is even more effective. 24. Re4 bxa3 Better here are moves such as 24... Rf6 or 24... Rf5 or 24... Ba6 or 24... e5 to finally activate the light squared bishop. The move played, while not bad in itself, simplifies White's defensive tasks. 25. Bxa3 Ba6 26. Rd1 Nb4? This knight is the keystone of Black's position, and White should have been considering sacrificing to remove it from it's post. For black to take it away voluntarily gives up all his advantage. 27. Rxe6 Bb5 27... Bf6 28. Rxg6+ Kh8 29. Rd7 Rae8? Black is suddenly very concerned with staving off mating threats, but the proper way to handle this is by 29... Rf6 Unfortunately, in the last five moves, Black's game went from probably won to almost certainly lost. 30. Bxh5 c5 31. Rd1 31. Rh6+ Kg8 32. Bxe8 Rxe8 33. Rg6+ Kh8 34. Bxb4 Bxb4 35. Ra7 is a fairly simple win. 31... Rf6? The rook on e8 should move. 32. Rxf6 exf6 33. Bxe8 Bxe8 34. Ne4 Ba4 35. Nxc3 Bxc2 36. Rd2 Bg6 37. Bxb4 The knight is less of a potential threat than connected passed pawns can be. This exchange only gives White opportunities to suffer serious consequences for small errors. 37... axb4 38. Nd1 c4 39. Rd8+ Kg7 40. Rc8 c3 41. Nxc3 The best and simplest way to handle the ending. 41... bxc3 42. Rxc3 Kh7 43. Rc6 Kg7 44. f4 Bf5 45. g4 1-0
