NJ Knockouts vs. Queens Pioneers
US Chess League 2008, Round 7
By Michael Goeller
The New Jersey Knockouts had an opportunity to overtake the Queens Pioneers on Monday night, October 6, 2008, in Round 7 of US Chess League action but ended up with only a 2-2 tie, despite having a significant advantage in the two drawn games. If New Jersey had won, they would have tied Queens for lead in the Eastern Division. Let’s hope that the 2-2 tieNew Jersey will meet Queens again in the playoffs and finally carry home the full point.
Board 1
Stripunsky-QNS (2601) – Benjamin-NJ (2644) [C41]
ICC 90 30 u/Internet Chess Club 2008
The second time that Benjamin has chosen the Philidor in USCL match play this season. It secured him a draw in Round 5 against GM Kudrin. It seems practically a bullet-proof weapon for Black on first board.
I like this move, which I have not looked at closely before. I have generally played 4… Nf6 5. Nc3 Be7 6. Bg5
|
6. Qd2
6. Bxd8 Nxd4 7. Nxd4 Kxd8 8. Bc4 Nh6 9. Nc3 c6 and “the two Bishops should guarantee Black an easy life in the endgame” notes Bauer.
6… Be7!
This seems the most logical move, trying to exchange “bad bishop” for “good.”
6… Nf6 7. Nc3 Be7 reaches more standard Philidor positions.
7. Bxe7 Qxe7 8. Nc3 Nf6 9.
10. Bd3 Nb4 11. Rhe1 Be6 12. a3 Nxd3+ 13. Qxd3 Rfe8= Seel
10… Qd8
10… Qxe4?! 11. Nxf6+ gxf6 12. Bd3 is too ugly to consider seriously.
a) 12. Nxf6+ Qxf6 13. Qxf6 gxf6 is pretty much equal with the Queens off the board.
b) 12. Bd3 Ng4! is given by Seel: 13. Rd2 Nce5 (13… Be6 14. h3 Nge5=) 14. Nxe5 dxe5 15. Qf3 c6 16. h3 cxd5 17. hxg4 d4 18. Rh5 Qa5 19. Bc4 Be6 leading to equality.
13… Be6 14. Rhe1 Qd7! 15. Re3!?
15. Kb1 Nb4 16. Bxe6 Qxe6 17. b3 Nc6= Seel
15… Nb4!
This seems simplest and best. Other moves risk material loss:
a) 15… Bxd5 16. exd5 Rxe3 17. dxc6! (17. Qxe3 Ne7 18. Qe4 Re8 19. Re1 h6 20. Nd4 Kf8 21. Qh7 Ng8=) 17… Rxf3 18. cxb7 Rb8 19. Qxf3 c6 20. Qa3 Qxb7 21. Rxd6
b) 15… Ne7 16. Bxb7!? Rab8 17. Bd5
16. a3
16… Nxd5 17. exd5 Bg4 18. Rde1 Rxe3 19. Rxe3 Bxf3 20. Qxf3 Re8 21. Qe2 Rxe3 22. Qxe3 g6=
White may appear to have more space and temporary control of the e-file, but these are insufficient claims on advantage. It seems Benjamin has chosen an “unbeatable” opening in the Philidor for team play.
Fritz points out 23… Qg4! 24. g3 Qh5 forking two pawns, and 25. Qa7 Qxh2 26. Qxb7 Qxf2 favors Black.
24. c4 Qf6 25. Kb1 a5 26. g4 h5 27. h3 hxg4 28. hxg4 Qh4 29. f3 Qh2 30. b4 axb4 31. axb4 Qg2 32. Qc3 Qe2 33. Kc1 b6 34. Kb1 Kf8 35. g5?! Kg8 36. Kc1 Qf2 37. Kb1 Qe2 38. Kc1
|
38… Qg2!
Suddenly White’s pawns are overextended and one must fall.
39. Kb1
39. Qe3 Qf1+ 40. Kb2 Qxc4 also snags a pawn.
39… Qxg5 40. Kb2 Qf5 41. Ka3 Kh7 42. Ka4 Qd7+ 43. Kb3 Qe7 44. Qd4 g5 45. Qg4 Kg6
You have to use your King in Queen endings if you are to make any progress.
46. Qc8 Kf6 47. Ka4 Ke5 48. Kb5 Kd4 49. Kc6 Kxc4 50. Qg4+ Kb3! 51. b5 Kc3 52. f4
|
52… gxf4
A safe play, but it will be impossible to escape perpetual after this. It is very difficult to calculate lines in Queen endings, but Fritz suggests: 52… Qe8+! 53. Kxc7 Qxb5 54. Qf3+ (54. Kxd6? Qc5+ 55. Ke5 Qd4+ 56. Kd6 Qxf4+ 57. Qxf4 gxf4 58. Ke7 f3) 54… Kd4 55. fxg5 Qxd5
53. Qxf4 Kd3 54. Qf3+ Kd4 55. Qd1+ Kc4 56. Qc2+ Kd4 57. Qd2+ Kc4 58. Qc2+ Kd4 59. Qd1+ Kc4 60. Qa4+ Kc3 61. Qa3+ Kc4 62. Qa2+ Kc3 63. Qa1+ Kc4 64. Qf1+ Kb4 65. Qb1+ Kc4 66. Qc2+ Kd4 67. Qd1+ Kc4 68. Qc2+ Kd4

Lenderman-QNS (2528) – Ippolito-NJ (2500) [B30]
ICC 90 30 u/Internet Chess Club 2008
Both Lenderman and Ippolito were in contention for MVP honors this season, so their match-up had special significance.
1. e4 c5 2. Nf3 Nc6 3. Bb5 e6 4. Bxc6 bxc6 5. e5 f6 6.
Opening specialist Jacob Aagaard demonstrated an even better method against White’s system: 6… Nh6! 7. Re1 Nf7 8. d4 cxd4 9. Qxd4 Be7! 10. Bd2
|
Perhaps an attempt at improvement on 8. d3 d6 9. Nc4 Be7 10. Bg5
8… d6 9. Nc4 Be7 10. d3
Black’s chief difficulty is in finding a way to mobilize his central pawn mass without creating weaknesses.
13… Nxc4 14. dxc4 Rb8 15. b3 Bf6 16. Rad1 (16. Rae1!?) 16… Bd4+ 17. Kh1 is similar to the game.
14. Rad1 Bd4+ 15. Kh1 Nxc4 16. dxc4 e5 17. Ne4! exf4
Black must act or have his Bishop trapped and his pawns become targets.
a) 17… Bxb2? 18. Rb1 (18. c3!? d5 19. Be3) 18… Ba3 19. fxe5
b) 17… d5!? might be tried: 18. Ng5 (18. c3 dxe4 19. cxd4 exd4 20. Qxe4 Qf6) 18… h6 19. c3 exf4!
18… Qh4!? 19. Bxd6 (19. Bg3 Bg4!) 19… Bg4 20. Rxf8+ Rxf8 21. Rf1! Rd8
19. Bxd6!?
This is an teresting sacrifice of two pieces for a Rook, but White may have had a simpler solution:
19. Qf3! Bg4 (19… d5 20. Bg5!) 20. Qxg4 Rxe4 21. Qf3
19… Qxd6 20. Nf6+ Bxf6 21. Qxe8+ Qf8 22. Qxc6 Bg4
22… Rb8! 23. Qd5+ Kh8 avoids the danger of the text move.
24… Be2!? 25. Rf4 Qg8 26. Re6 Bh5
Black is in a bad way due to the threat of g4-g5, but there seems no perfect solution.
a) 25… Bf7 26. g5 Rd8 27. Rxd8 Bxd8 28. Qd7 Be7 29. Qxa7
b) 25… Rb8!? 26. gxh5 Rb6 27. Rdxf6 gxf6 28. Qe4 Rxb2 29. h6!
|
29… Qc6+ 30. Kg1 Rg8 31. Kh2! Qd6+ 32. Kh1 Qc6+ 33. Qd5
30. Qxf6+ Qxf6 31. Rxf6 Rd2 32. Ra6! Rxc2 33. b3 Kg7 34. h4!?
34. Rxa7+ Kg6 35. Rc7! Kg5!? (35… Rxa2 36. Rxc5) 36. Rxc5+ Kh4 37. Rd5 Kxh3 38. Rd3+ Kg4 39. a4
34… h5 35. Rxa7+ Kg6 36. Ra5 Kf5 37. Rxc5+ Kg4 38. Rg5+ Kxh4 39. Rg2 Rc1+ 40. Kh2

41. bxc4 is stalemate, of course. But Lenderman has an easy win if he just doesn’t take the Rook!
41… Rc3 42. b4 Rh3+ 43. Kg2 Rg3+ 44. Kh1 Rc3 45. b5 Rc1+
46. Kh2 Kg4 47. b6 Rc8 48. b7 Rb8 49. a4 Kf4 50. a5
Black resigns. A fine game for Lenderman.

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. d3 Bc5 5. c3 a6 6.
After analyzing this game, I have a lot of respect for the Closed Giuoco lines, where White has generally done very well. One game from this position continued 9. a4 Qe7 10. Nbd2
9… Qe7 10. b4 Be6 11. a4
White might break on the queenside immediately with 12. b5! Nb8!? (the knight seems misplaced after 12… Na5 13. Bxe6 Qxe6 14. Re1) 13. Qb3 Nbd7 14. Rfb1 g5 15. Bg3 Nh5 16. bxa6 bxa6 17.

13. Nxc4 Qe6 14. b5 Ne7! 15. Qb3 Ng6 16. Bg3 Nh5 17. Rab1 Nxg3?!
Taking the Bishop looks like a mistake, mostly because it is simply a bad piece. It looks like Black has good chances of equality by 17… Ngf4! since White will not want to exchange on f4 and hand that square to Black. After 17…Nxg3?! White gets rid of his worst piece and gains control over f4.
18… axb5 19. axb5 (19. Qxb5 Rfb8) 19… Rfc8 20. Re2
19. b6! cxb6 20. Nxb6 Rad8 21. Qxe6 fxe6 22. Re2! Nc6 23. Nc4
23. g4 Na5! (23… g5 24. Nc4) 24. g5 Rf7 25. gxh6 gxh6 26. Nd2
25… Kf8 26. Nb6 Bxb6!? 27. Rxb6 Ke8 28. Nd2 Na5! 29. Ke2 Kd8 30. Ke3 Nc6 31. f4 exf4+?!

A better way to exploit Black’s last was 33. Nb3! (heading for Nc5) 33… e5 34. f5 d4+ 35. cxd4 Nxd4 36. Nc5!
33… d4+ 34. cxd4 Nxd4 35. Nc4 Nc6 36. e5!
Creating a beautiful square for the Knight. Perhaps 36. Rxc6!? bxc6 37. Ne5 Rb7 (37… Kc7 38. a5!) 38. Nxf7+ Rxf7 39. Rb6 was a safe way to play for the win.
36… Rfe7 37. Nd6 Na5 38. Ne4 Rc7 39. Rd6+ Kc8 40. Rbb6 Rc6 41. Rbxc6+ Nxc6 42. Nc5 Nd8 43. d4 Kc7 44. g4 g6 45. Kf3
White wins quickly with 45. d5! h5 (45… exd5 46. Rxg6) (45… g5 46. Nxe6+ Nxe6 47. dxe6 gxf4+ 48. Kxf4) 46. gxh5 gxh5 47. Nxe6+ Nxe6 48. dxe6 h4 49. f5 h3 50. f6 Ng has played the game so wonderfully up to here, it is a shame to see him slowly spoil it, likely due to time pressure.
45… Nc6 46. Ke4 Nd8 47. d5 exd5+ 48. Kxd5 h5
48… g5 49. f5 Rxe5+ 50. Kxe5 Nf7+ 51. Ke6 Nxd6 52. f6
49. Rxg6 hxg4 50. Rxg4 Nc6 51. e6
Maybe better is 51. Ne6+ Kc8 (51… Kb6 52. Rg7 Re8 53. f5) 52. Rg8+ Kd7 53. f5
Certainly winning was 52. Nxa6+! Kb7 53. f5! when Black cannot exploit the Knight’s position due to his own Knight hanging — and meanwhile White’s pawns get rolling.
53. f5! Ne7+ 54. Ke4 Kd6 55. Nf4 Rh6 56. Rg3
54. Ke5! Nc6+ 55. Kf6 seems like a clear winning line, and perhaps the last one available.
54… Kd6 55. Re5 Rh2 56. Kf3 Rh6 57. Nb2 b5 58. axb5 axb5 59. Rxb5 Rxe6
Suddenly the endgame is going to be hell to win, since Black can always sac the Knight for the pawn, bringing about the notoriously drawn R+N v R ending.
60. Nc4+ Kd7 61. Ne5+ Kc7 62. Ke4 Ra6 63. Rb4 Ra1 64. Rd4 Re1+ 65. Kf3 Nf5 66. Rd2 Rg1 67. Ke4 Ng3+ 68. Kd5 Rf1 69. Rc2+ Kb7 70. Rc4 Nh5 71. Ng6 Kb6 72. Ke6 Kb5 73. Rd4 Re1+ 74. Kd6 Nf6
74… Nxf4! right away guaranteed the draw.
75. Ne5 Rf1 76. Ke6 Nh5 77. Nd3 Nxf4+! 78. Nxf4 Kc5
79. Re4 Rh1 80. Nd3+ Kc6 81. Rc4+ Kb5 82. Rc3 Rh6+ 83. Kd5 Rh5+ 84. Ne5 Kb4 85. Rc8 Rh1 86. Nd3+ Kb3 87. Nf2 Rh5+ 88. Kd4 Rh7 89. Rc3+ Kb4 90. Nd3+ Kb5 91. Rc5+ Kb6 92. Ne5 Rh4+ 93. Kd5 Rh1 94. Nd7+ Kb7 95. Kd6 Rh6+
Game drawn by mutual agreement. White missed many winning chances here, likely in time pressure.
