1. e4 c5 2. f4 d5 3. Nc3 dxe4 4. Nxe4 Qc7 5. Nf3 Nf6 6. d3 Nc6 7. Be2

I don`t like this move.Bishop on e2 stands too passive.And black begin to threaten f4 .

7... Nd5! 8. Qd2 Bf5 9. O-O Rd8 10. Ne5

Sharp tactical battle starts already after the opening.Human player can only feel scared and observe such brave sharpness.

10... Nxe5 11. fxe5 e6! 12. Bh5

White have counted bad creating their cavalryman`s attacks.Now they must sacrifice a pawn for an unclear, indistinct initiative.Sure it is not the strongest feature of the computers to do this;especially playing another computer.But it is impossible to avoid sacrifice already.

12... Qxe5 13. Qa5 Bg6 14. Bf3 a6 15. Kh1

If a program makes such a move- it is already bad.

15... Bxe4 16. Bxe4 Rd7!? 17. Qa4 Bd6 18. g3 h5!

Good !Not even thinking about slowly realization of a pawn.

19. c3 g5->


20. Bf3 Be7 21. Bd2 h4 22. g4 Nb6 23. Qc2 h3 24. Rae1 Qd6 25. Qc1 Rg8 26. Be4

Seems white manage to creat a contragame/?/

26... Nc4!!

But black locate their knight to king`s flang with temp wining.

27. Be3 Ne5 28. Bxc5

Time had come for a tactical duel. Interesting to know how far REBEL-CENTURY3 had counted for that moment.

28... Qc7! 29. Bxe7 Nxg4! 30. Qc2 Rxe7 31. Re2 Kd8!? 32. Qa4 Ne5 33. Qd4+ Nd7 34. Qe3 g4

The main white`s problem is not a lost pawn, but a loop coming to a white kings neck.

35. Bh7 Rg7 36. Bf5 f6 37. Qh6 Rg8 38. Be4

Now it may look as a task for proffesional players-how black must win? 10points.

38... f5!! 39. Bxf5! Rf8!! 40. Rxe6 Rxf5!! 41. Qh8+ Nf8 42. Rxf5 Qc6+! 43. Re4 Rxe4 44. Kg1 Re1+ 45. Kf2 Re8 46. Qf6+

If not to trade the queen, a king will stay in a mate trap.

46... Qxf6-+

Tactical tension ends here,but result is clear. Human player would resign now.

47. Rxf6 Nd7 48. Rf4 g3+

original decision

49. Kxg3 Re3+ 50. Rf3 Rxf3+ 51. Kxf3 Ne5+ 52. Kg3 Nxd3 53. b4 b5 54. Kxh3 Nf2+ 55. Kh4 Ne4 56. Kh5 Nxc3 57. a3 Ke7 58. Kg6 Nb1 59. Kg7 Nxa3 60. h4 Nc4 61. h5 Ne3 62. Kg6 Kf8 63. Kg5

Wonderful game.Computers fighting as for life or death!We may admire.As a game has really great AESTHETICAL value!

Odyssey2001-Tournament (2)
k6-400, 40/120

This game is difficult to comment.Black had advantage,did well searching the win chances,but at the finish victory has come to whites!Let`s see how it had happened.

1. c4 e5 2. g3 Nc6 3. Bg2 g6 4. Nc3 Bg7 5. e4 d6 6. Nge2 Be6 7. d3 Qd7 8. Nd5 Nce7 9. d4 c6

We have rather popular line of English opening. White have 2 plans: to trade knights with idea of d5.Or 10.Ne3-as it did Garry Kasparov playing vs N.Short in Linares1990. Plan n2 seems more attractive for me as black has difficulties to find game plan in general,no static centrum, f7-f5 line not useful.

10. Nxe7 Nxe7 11. d5 Bh3 12. dxc6!?

Important moment now.White are giving centrum,hoping to make pressure on it later.Rather traditional plan:12.0-0 Bxg2 13.Kxg2 0-0 14.Be3 f5 15.f3-simple.

12... bxc6 13. O-O Bxg2 14. Kxg2 O-O 15. b3 f5 16. Ba3 Rad8 17. Nc3

White continue their risky plan. Possible here 17.f3 and if 17....-fxe4 18.fxe4 Rxf1 19.Qxf1 d5 20. Rd1 d4 21.Nb1 blockading the pawn. Also brave and interesting simply: 17. .. -d5!

17... fxe4 18. Nxe4 d5 19. cxd5 cxd5 20. Nc5 Qc8 21. Rc1 Rf7

First impre ssion says that white have better.But how they must continue ?While task for blacks is more easy.

22. Qe2 Nc6 23. Bb2 Bh6 24. Rcd1 e4!

Typicall computer `s move! I doubt if a human would decide such a game. Nevertheless black can find interesting game against white king through the field f3.

25. f4!?

White`s answer not less original:).Whites see the danger about f3 and try to eliminate it.But they dont pay attention to a double pawns going in the centrum!Thus the fight begins about d5-pawn.If black will suceed to push it-they willwin!

25... Nb4 26. Qe3 Bf8 27. Qd4 Bg7 28. Qxb4 Bxb2 29. Qd2 Bf6?

This mistake of black`s is very clear! They had a chance now to push d4! 29..-Qc5! 30.Qb2 d4-+.

30. Rc1 Qf5

Black still trying to promote d4,but now it is too late.Analyzing far variations i failed to find clear win for blacks here now.

31. Qe2! Re7 32. g4!

White suceeded to do this in time.

32... Qc8 33. f5!

This pawn gives some chances for white contragame

33... Rc7 34. b4 Bd4 35. f6[] Bxc5 36. Rxc5 Rxc5 37. bxc5 Rf8 38. g5

Of course f6 pawn is like a splinter in black`s..hmmm.... body

38... Qxc5 39. Qa6 Qb6 40. Qa4 Qc7 41. h4 Qf7 42. Qd4 Qd7 43. Rf4 Rf7 44. Qe5 Qc7 45. Qe8+ Rf8 46. Qe6+ Qf7 47. Qd6 Re8 48. Kf2 Rc8 49. Ke1 h5 50. Kf1 Kh7 51. Rf2 e3 52. Rb2 Qc7??

Difficult to believe-but black are going to a lost endgame step by step.Again we must see the conclusion: the positional apprehension of endgame is what the programs lack!!!

53. Qxc7+ Rxc7 54. Ke2 d4? 55. Kd3+- Rc3+ 56. Kxd4 Ra3 57. Re2 Ra4+ 58. Kxe3 Rxh4 59. Rd2 Kg8 60. Rd8+ Kf7 61. Rd7+ Kf8 62. Rg7 Rh3+ 63. Ke4 Rh4+ 64. Ke5 Rh1 65. Rxg6 Re1+ 66. Kd4 Rd1+ 67. Ke3 Rg1 68. Ke4 Re1+ 69. Kf3 Rf1+ 70. Kg2 Rf4 71. Rg7 a5 72. Kg3 Rg4+ 73. Kf2 Rf4+ 74. Ke2 Rg4 75. Ke3 a4 76. a3 Rh4 77. g6 Rg4 78. Kf3

My last remark explains this result the best! Game was complicated.Black had missed their chance-remember d4pawn pushing moment.Then white managed better to realize the endgame and poor endgame understanding didnt let ChessGenius at least to draw the game. Gambit-Tiger has important point.
