1. d4 Nf6 2. c4 c5 3. d5 d6

Benoni defense, Hromodka System after 3... d6

Benoni defense, Hromodka System after 3… d6

Usually I play 3… b5 here trying for the Benko Gambit. Here I decided to defer the Benko moves in order to avoid certain lines that favor White.

4. Nc3 a6 5. Qd3 b5

Benoni defense, Hromodka System after 5... b5

Benoni defense, Hromodka System after 5… b5

I have no idea what White’s last move was supposed to accomplish! Here Black goes for the Benko Gambit.

6. cxb5 g6 7. Be3 Bg7 8. Bf4 O-O

Benoni defense, Hromodka System after 8... 0-0

Benoni defense, Hromodka System after 8… 0-0

Black has completed his Kingside development and has castled. White has completed his Queenside development and has moved the dark-squared Bishop twice before developing his other pieces. Black is down a pawn but gets compensation for it with his Queenside attack.

9. e3 axb5 10. Nxb5 Qa5+

Benoni defense, Hromodka System after 10... Qa5+

Benoni defense, Hromodka System after 10… Qa5+

Black begins his Queenside attack. Also good is 10… Ba6 pinning the White Knight to the White Queen.

11. Nc3 (Moving this Knight a third time.) Ba6 12. Qd2 Bxf1!

Benoni defense, Hromodka System after 12 Bxf1!

Benoni defense, Hromodka System after 12 Bxf1!

Now Black has what he wanted for his pawn, a slight lead in development, and the White King stuck in the Center of the board.

13. Kxf1 Nbd7 14. Bg3 Nb6

Benoni defense, Hromodka System after 14... Nb6

Benoni defense, Hromodka System after 14… Nb6

Black threatens to capture the pawn on d5. If White captures with the Knight on c3 then his Queen is unprotected and lost.

15. Qd1 Nbxd5 16. Nxd5 Nxd5 17. Qxd5 Bxb2

Benoni defense, Hromodka System after 17... Bxb2

Benoni defense, Hromodka System after 17… Bxb2

Black is down a Knight versus a pawn but White has a Knight and Rook that have yet to get into the game, so Black has some compensation for his material.

18. Re1 Qb5+ 19. Re2 Rfb8

Benoni defense, Hromodka System after 19... Rfb8

Benoni defense, Hromodka System after 19… Rfb8

Now Black has completed his development and has all of his pieces (except his King) on the Queenside. White still has a Rook and Knight that have yet to get into the game and his Bishop isn’t doing much.

20. Bh4 Ra7 21. Nh3 Rba8

Benoni defense, Hromodka System after 21... Rba8

Benoni defense, Hromodka System after 21… Rba8

Black can now win the a pawn but has some threats against his own Center pawns. Black threatens to capture on a2 and then mate on a1. The White Knight isn’t doing much on the edge of the board so White moves it to a better square. Note that the White King’s Rook still is not into the game yet.

22. Ng5 e6 23. Qd2 Rxa2

Benoni defense, Hromodka System after 23... Rxa2

Benoni defense, Hromodka System after 23… Rxa2

Black threatens to mate in two with 24… Ra1+ 25. Qd1 Rxd1#.

24. Nf3 Ra1+ 25. Ne1 Be5

Benoni defense, Hromodka System after 25... Be5

Benoni defense, Hromodka System after 25… Be5

White is still up material but Black has the attack. Black also has a passed pawn on the c file. Advancing the Center pawns seems to be the prudent thing to do.

26. e4 c4 27. Kg1 c3

Benoni defense, Hromodka System after 27... c3

Benoni defense, Hromodka System after 27… c3

Passed pawns must be pushed! And, the dark-squared Bishop on e5 anchors the pawn on c3 nicely. White is still, in effect, playing down a Rook.

28. Qc2 Qb2 29. f3 Qxc2 30. Rxc2 Bd4+

Benoni defense, Hromodka System after 30... Bd4+

Benoni defense, Hromodka System after 30… Bd4+

Black is still down a Knight for two pawns but White still has a Rook that is totally out of play. Thus, Black can afford to trade off pieces that are blocking the advance of the passed c pawn.

31. Kf1 (I think that 31. Bf2 is better for White.) Rb8 32. Re2 Rb2!

Benoni defense, Hromodka System after 32... Rb2!

Benoni defense, Hromodka System after 32… Rb2!

White cannot stop Black from queening the c pawn.

33. e5 dxe5 (Black is now even on material.) 34. Bf6 c2 35. Bg5 c1=Q

Benoni defense, Hromodka System after 35... c1=Q

Benoni defense, Hromodka System after 35… c1=Q

Although the Queen’s lifespan is very short it does serve a purpose. Black will be up a Bishop and two pawns after the exchange on c1. We are now 35 moves into the game and the White King’s Rook is still out of play!

36. Bxc1 Rxc1 37. g4 Rxe2 38. Kxe2 Bc3

Benoni defense, Hromodka System after 38... Bc3

Benoni defense, Hromodka System after 38… Bc3

Black is threatening to exchange on e1 and the White Knight is pinned because White will lose the Rook on h1 if the Knight moves right now. Black is up two pawns and one of them is doubled. So, Black needs to undouble his pawns.

39. h4 f5 40. g5 Kf7 41. Rg1 Rxe1+ 42. Rxe1 Bxe1 43. Kxe1

Benoni defense, Hromodka System after 43. Kxe1

Benoni defense, Hromodka System after 43. Kxe1

All of the minor pieces are now off the board and we have a King and pawn endgame where Black is up two pawns but one of them is doubled. Black still needs to undouble his pawns to have a clear advantage here.

Ke7 44. Kf1 Kd6 45. Kf2 Kd5 46. Ke3 Kc4

Benoni defense, Hromodka System after 46... Kc4

Benoni defense, Hromodka System after 46… Kc4

Black is trying to get the opposition here. He wants to get the White King out of position and then exchange the doubled e pawn for White’s f pawn.

47. Kd2 Kd4 48. Ke2 e4

Benoni defense, Hromodka System after 48... e4

Benoni defense, Hromodka System after 48… e4

Mission accomplished. Now White cannot avoid trading his f pawn for Black’s doubled e pawn.

49. fxe4 fxe4 (Kxe4 was better giving Black connected passed pawns.) 50. Kf2 Kd3 51. Kg1 Ke3 52. Kf1 Kf3

Benoni defense, Hromodka System after 52... Kf3

Benoni defense, Hromodka System after 52… Kf3

White has the opposition. Instead of trying to queen the pawn on e4 Black goes after White’s two remaining pawns. Play could continue here 53. Ke1 e3 54. Kf1 e2+ 55. Ke1 e5! 56. Kd2 Kf2 57. Kd3 e1=Q and Black quickly wins from there.

53. Ke1 Kg4 54. Kf2 Kxh4 55. Ke3 Kxg5

Benoni defense, Hromodka System after 55... Kxg5

Benoni defense, Hromodka System after 55… Kxg5

Black is now up 4 passed pawn with one of them being doubled. I would expect most human players to resign here. I see no point of commenting on the rest of the game.

56. Ke2? (Why not take the pawn on e4?) Kf4 57. Kf2 e3+ 58. Ke1 Kf3 59. Kf1 h5 60. Ke1 e2 61. Kd2 Kf2 62. Kc3 e1=Q+ 63. Kc2 Qb4 64. Kd3 e5 65. Kc2 Ke2 66. Kc1 Qc3+ 67. Kb1 Kd2 68. Ka2 Qb4 69. Ka1 Kc2 70. Ka2 Qb2# 0-1

Benoni defense, Hromodka System after 70... Qb2# (Final position)
