1. e4 e5 2. Nf3 d6 3. d4 exd4 4. Nxd4 Nf6 5. Nc3 Be7 6. g3 Nc6

I like this simple move.

6... d5 is considered by theory the more critical move, when White might play 7. exd5 (7. e5!? Ng4 8. Bf4 (8. Bg2!?) 8... g5 9. e6 h5) 7... Nxd5 8. Ndb5 (8. Bd2 O-O 9. Bg2 Nb6 10. Be3 Nc4=) 8... Nxc3 9. Qxd8+ Bxd8 10. Nxc3 Bf5 11. Bg2 Nc6 12. O-O O-O 13. Bf4 Bxc2 14. Rac1 Bf5 15. Rfd1 Seel

10. O-O

White does best to castle on the kingside, since queenside castling has proven a problem in practice: 10. f4 Nd7 11. Be3 Nb6 12. O-O-O?! Nc4 13. Bf2 c5 14. Qd3 Qa5 15. Kb1 Qb4 16. b3 Na3+ 17.

10... c6 11. Be3

Stopping Qb6, trading queens and easing Black's game. But Black has other ways of organizing his forces in this flexible defensive position.

11... Qc8!

11... Qa5 12. f4

12. Kh2 Rd8 13. Rad1 d5

A bid for immediate equality, but this may be premature.

An interesting forcing line is 14. e5 Nd7 15. f4 c5!? (15... f6!=) 16. Nxd5 cxd4 17. Nxe7+ Kf8 18. Nxc8 dxe3 19. f5 (19. Rxd7 Rdxc8) 19... Bxa2

14... Nxd5 15. Nxd5 Bxd5 16. Bxd5 Rxd5 17. Qe4










17... Qe6!?

A very inter esting solution to Black's problems and the best way to avoid an isolated pawn at d5 or surrendering the d-file.

18. Qxe6 fxe6 19. c4 Rdd8 20. Kg2 Kf7 21. Kf3 b6

White retains a slight structural edge, but it is too little to win with in this position.

Nc3 e5 Black clearly has the better structure, but White's pieces create great attacking chances all on their own. How this seems to work is that Black has stopped up the dark squares at the expense of the light -- the indirect impact of the b2-Bishop. 12. Nh4 O-O 13. Ne4!? Qd8 14. Ng3 Ne6 15. Qe4 Ng5 16. Qe3 g6 17. Rae1 Bd6 18. Ne4 Nxe4 19. Bxe4 Ne7 20. b4!? Qb6 21. b5 a6 22. Qh6! Rf7 23. f4 exf4 24. Bd5? (24. Bxg6! Nxg6 25. Nxg6 Qd8 26. Nxf4) 24... Nxd5 25. cxd5 c4+ 26. Kh1 Be5? (26... Qxb5 27.

b) 6... g6!? seems like a new idea worth noting: 7. Na3 Bg7 8. Nc4 O-O "Just in time castling..." 9. Bg2 b6 10. O-O Ba6 11. d3 Bxc4 12. dxc4 Nde7 13. Qe2 Qc7 14. Rae1 Rad8 15.

Qxd1 f5 0-1 De la Riva Aguado,O-Ponomariov,R/Pamplona 2005 (52), and Black's superior majority favored him.

7. Bg2 O-O 8. O-O d6 9. d4?!

9. exd6 Qxd6 10. Na3 with the id ea of Nc4 seems most appropriate here, taking advantage of the fact that White has not yet played the c4 advance.

9... cxd4 10. exd6 Qxd6 11. Nxd4 Nxd4 12. Bxd4 Rd8

Black has emerged from the opening with a good game and now just needs to activate his Bishops and perhaps exchange White's better ones.

13. Bb2 Qc7 14. Qe2 Bf6 15. Bxf6 Nxf6 16. Na3 Bd7 17. Rfd1 Bc6! 18. c4 Qa5 19. Nb5 Bxg2 20. Kxg2 a6 21. Nd4 h6

A fairly equal position, though Black's pieces are better placed. White might have hopes of making his queenside majority do something.

22. Nf3 Qf5 23. Rd4 Rxd4 24. Nxd4 Qc5 25. Nc2 Rd8 26. Ne3 Qc6+ 27. Qf3 Rd2! 28. Qxc6 bxc6 29. Kf3 a5 30. a3? Rb2

Black wins a pawn, but it will be hard to make it pay.

31. b4 axb4 32. axb4 Rxb4 33. Ra8+ Kh7 34. Rc8 Nd7 35. Ke4 f5+

Perhaps Black should surrender the c-pawn for the kingside pawns? 35... Rb2!

36. Kd4 Rb6 37. Rc7 c5+ 38. Kc3 Rd6 39. Ng2! g5 40. Ne1 Kg6 41. Nd3

After a great Knight re-routing, White wins back the pawn and gains a passer.

41... Kf6 42. Nxc5 Nxc5 43. Rxc5 Rd1 44. Rb5 Rh1 45. Rb2 Rxh2 46. c5 Rh1 47. Kc4 Rc1+ 48. Kb5 h5 49. c6 h4 50. gxh4 gxh4 51. f4 e5 52. fxe5+ Kxe5 53. Rh2 Kd5 54. Rd2+ Ke4 55. Rh2 Kd5 56. Rd2+ Ke5 57. Rh2 f4 58. Rxh4

An obvious draw result. Each Rook will be forced to sacrifice itself for the other's pawn.

58... f3 59. Rh2 Kf4 60. Rh8 f2 61. Rf8+ Ke3 62. Kb6 Rb1+ 63. Ka7 f1=Q 64. Rxf1 Rxf1 65. c7 Rc1 66. Kb7 Kd4 67. c8=Q Rxc8 68. Kxc8

Game drawn because neither player has mating material. A classic battle "to the Kings"!

We now have the tabiya of a classic MacCutcheon confrontation. White has good chances on the kingside and Black on the queenside. But White's superior development allows him to inhibit Black's queenside play somewhat if he chooses -- as Ng does here.

Black also sometimes plays the inferior 10... Qg5+ 11. Qxg5 hxg5 12. g4 (12. f4 gxf4 13. Rf1) 12... f6 13. h4! fxe5 14. dxe5 Nc6 15. Nf3 gxh4 16. Rae1 Psakhis

A concept of Akobian's, to fix White's a-pawn on a light square so it can be attacked by the Black Bishop.
