2011 Feb/Mar Chess Positions

First, Some Warmup Positions


USATW, r3, Feb 20, 2011

Black just played Be7-b4.
White to Play.


ICC game

White to Play.

South Houston Open, Mar 12, 2011

White to Play.
Here I had just played ..Bf5 to prevent Rh3#, and with the desperate hope he will take the hanging Bishop. He didn't.

An Escape


USATW, r1, Feb 19, 2011
Playing Winston Zeng, all of nine years old, I got a space edge out of the opening, but as the time control approached, I was unable to whip up any kind of attack. Meanwhile he pillaged my queenside, leaving me with a two-pawn deficit and hazy compensation:

I played 45. Kh2 so that my queen could vacate the first rank and that even though the Bc1 would be hanging, it would not be with check. Objectively speaking, I'm still busted. Play continued ..Bh4 46. Qh3 Qxc1 leading to this position:

I played 47. Qxh4 (47.Rxh7+ does not lead to a perpetual check: 47..Kxh7 48. Qxh4+ Kg7 49.Bxg6 Rh8! (not 49..Kxg6? which does lead to a perpetual check for W) 50. Bh5 Qc2+ 51. Kh3 Rxh5! 52. Qxh5 Qg6!) ..Qb2+ (47..Nxh4?? 48. Rxh7#) 48. Kh3 leading to this position:

Here Black played Qb2-b7. What did I do? What should he have done?


An Amazing (Imaginary) Escape



White to Play and Draw.
This only came up in analysis, but it is pretty cool nonetheless.

Well... Rxf6 for the first one and Nf6 for the second one.

Rg5 for the third one?

Against Winston, you played 49. Qf6ch and after either interposition, 50. Bxg6 for free. Instead of Qb7, Winston should have played 48. Qg2ch, 49. Kxg2, Nxh4 with double check, 50. K anywhere, N returns to g6, safely retaining his 2 pawn advantage with Kg7 to follow. It's 20 years since I was rated in the high 1900s at chess, but Larry's been playing some online lately so from kibitzing him, some of my tactics have been revived.

I want to guess Bh7 in the last one, threatening either Bd3 or if Kd4, Bf5 and Bh3 to defend against promotion on f1, but I'm having trouble seeing how you can get all three black pawns off the board from that point, or how black can get yours, so it's not clear to me that one of you should not still win, or which one. And I'm too lazy to dig out a real board and work it out the cheater's way with moving pieces.

Absolutely right regarding Zeng game. I saw the Qg2 resource as soon as I played Qxh4, and had to sit there with my poker face for a bit.

Incorrect regarding the BNvN ending.

How about Na5 followed by Nc4+ claiming F1 square for draw? Thanks
