Stoyko, Bartell, Goeller and co. - Allen, Kernighan, Moldovan, Bilenky & co. [D12]
Kenilworth Consultation Game/Kenilworth, NJ 2007
D12 Queen's Gambit Slav Defense
The WHITE team starts with a lineup of FM Steve Stoyko, Michael Goeller, Greg Tomkovich, Ed Selling, Bert Shiffman & Joe Azzarello.
The BLACK side begins with NM Mark Kernighan, NM Ed Allen, Mark Bilenky, John Moldovan, Joe Renna & Max Sherer.
Mark B. thought 7... Bb4 was more consistent because after the game's 9.e4, Black has to give up the center.
8... Bb4! 9. Bd2 a5 10. a3 Be7 11. b4
FM Tom Bartell & Pat Mazzillo have joined the White crew. Brian Meinders joined Black.
At this point, play was adjourned. When we resumed on May 24th, the sealed move was revealed :
WHITE, which lost Bert Shiffman & Joe Azzarello, adds Harry Smith & Leon Hrebinka along with the side-switching Mike Wojcio & Max Sherer. BLACK, which lost NM Ed Allen adds Joe Demetrick & Pete Cavaliere.
White has systematically worked to stifle Black's counterplay, discouraging all of his breaks by ...b5, ...c5 or ...e5.
This seems ndecisive. Perhaps the idea is to indirectly attack the unsupported Bishop at c3 and thus support the ...b5 thrust by tactical means. But Black's Rooks are poorly placed and the move wastes time.
White has a big space advantage and complete control of the game. Now he has to start thinking about how to begin an attack, but some precautions are useful. Stoyko thought it was a good idea to avoid an exchange of Queens to strengthen White's eventual attack.
Black naturally welcomes the exchange. This waffling by the Black Queen, though, highlights how Black's position is completely devoid of useful plans.
19. Qd2 is also possible.
Probably Black's best chance at getting a pawn break, but his waffling has made it less useful than it might have been.
Time to get the Knight to a useful attacking square via e4. The Knight also plays a useful role here protecting c4.
To discourage Ne4.
Black threatened 21... Bxh7+! and had ideas like ...Ng4 or ...Qh5, so White simply takes away all of that play and limits Black's Knight's mobility -- while also creating some useful luft.
This seems very passive and planless.
Black must try to break with 21... b5! when things get a bit unsettled and Black gains a critical square for his Knight at d5: 22. axb5 cxb5 23. d5!? ( or 23. c5 Nd5! 24. Qf3 Ra8 (24... Rb7?? 25. cxd6!) 25. Ra6 Bc7 26. Ne4 with the idea of Rea1 and the bind continues) 23... bxc4 (23... exd5 24. c5) 24. dxe6 Nd5! 25. Qd4 fxe6 26. Rxe6 Nxc3! 27. Qxd6 Qd3 and Black gets a fighting chance.
Stifling Black's last chance for counterplay!
More waffling. Black can find nothing useful now.
Inducing Black to exchange pawns or push, after which White gains useful open lines.
Better 23... cxb5 24. axb5 Rc7 when White has a clear edge but has to be careful: 25. Ra4 (25. Ra2 is simpler) 25... Qc2 26. Rea1 Nd5 27. Ne4! f5!? 28. Nxd6 Nxc3 29. R4a3! (29. Rxa7? Rxa7 30. Rxa7 Ne2+ 31. Kh2 Qd1!! 32. Ra1 Qxd4 (32... Qxa1?? 33. Qxe2) 33. Qxe2 Qxd6+ 34. g3 e5=) 29... Ne2+ 30. Kh2
A nearly pointless move, with the passive goal of defending b6 in case of a5 perhaps.
Moldovan appears to think 40... Kg5!? would have changed matters, and that's possible. Unfortunately, I don't have time for a complete analysis, though the lines are very interesting--and here is one fantasy variation: 41. Kf3 (41. Ne5? Kf4 42. Nxf7 Rd7 43. e5 Kxf5) 41... f6 (41... Kh4?? 42. e5) 42. Kg3 Re8 (42... Rd7 43. h4+ Kh5 44. Kf4!) 43. h4+ Kh5 44. e5 (44. Kf4? Kxh4 45. e5 fxe5+ 46. Nxe5 Rd8 47. d7 c4 48. f6 c3!) 44... fxe5 45. d7 Rd8 46. Nxe5 c4! 47. Kf4 c3! (47... Kxh4 48. Ke4 c3! 49. Kd3 Kg3) 48. Ke3 Kxh4 49. Kd3 Kg3 50. Kxc3 h5! 51. f6 Kf4 52. Kd4 h4 (perhaps 52... Kf5 53. Kd5 Kxf6 54. Kd6 h4 55. Nd3 Rg8) 53. f7 Kf5 54. Kd5 h3 55. Kd6 h2 56. Kc7 h1=Q 57. Kxd8 Qh8+ 58. f8=Q+ Qxf8+ 59. Kc7
or 47. Nd6
and Black cannot avoid mate
