   Aug-27-17 Larsen vs K Darga, 1967
wwall: Looks like Larsen fell for a poisoned pawn after 28.Bxf6? He should have ignored the pawn and play 28.Re1 or 28.Qe1. After 28...Rxd6! 29.Qxd6 Rd8!, White cannot play 30.Qxc6? due to 30...Rxd1+ 31.Bf1 Qb4 and Qb1 wins the bishop. Also, 30.Qxe7? Rxd1+ 31.Bf1 Nxe7 wins for Black. Instead
   Aug-26-17 Steinitz vs Pillsbury, 1892
wwall: Looks like the losing move was 25.Kc2. White had to play 25.Qe1, and if 25...Na6, then 26.Nc2 and 27.b4 should hold for White. Instead of 26...Rd8, Black could have played 26...Qxc3, and if 27.Rc1 or 27.Qc2, then 27...Nxe4 wins.
   Aug-25-17 Pillsbury vs F Young, 1890
wwall: Not sure if this game was a sign of brilliance. Pillsbury played 9.Nc3? and should have lost after 9...d4 (threatening 10...d3) 10.exd4 cxd4 11.Nb5 d3, winning a piece. After 9.Nc6, Pillsbury as White misses the threat again (and Black misses the winning move again) with 10.a3? since ...
   Aug-18-17 Larsen vs Ivkov, 1967
wwall: Perhaps 27...Nc4 is the losing move. Black can try 27...Kg8 28.Nf4 Rh6 and hold. 29.Nxg6 doesn't work after 29...fxg6 30.Bxg6+ Kg8 31.Ne6 Rg6 Instead of 29...Kg8, if 29...fxg6, then 30.Nxg6 Qf7 31.Nxh8 Kxh8 32.Qh4+ Kg8 33.Rxc4 dxc4 34.Qd8+ Kh7 35.Qxb6 Bf3 36.g4 Bxg4 37.Ra7 Qf5 38.Qb7 ...
   Aug-13-17 B Kostic vs Tartakower, 1950
wwall: Instead of 20.Qb4, perhaps stronger is 20.Nxg7, and if 20...Qg4, then 21.Rxf7 Qxd4+ 22.Kh1 Nc6 23.Ne6, forking queen and rook. 23...bxc6?? leads to mate. Black may be able to play 23...Qxc6 24.Qxc6 bxc6 25.e6 Re8 26.Nxg7 Re7 and perhaps hold. After 24.Nd6 cxd6 25.Rb1+ Kc7 26.Qxa7+ Kd8
   Aug-07-17 J H Donner vs Euwe, 1943
wwall: Perhaps 35.h4 is the losing move as Black can chase the pawn down and win it. Better may be 35.Ke3, and if 35...Nf5+, then 36.Kf4 and 37.Ne4.
   Aug-05-17 Blau vs M Christoffel, 1944
wwall: Instead of 19...Qc2, perhaps best is 19...Qd1+ 20.Rf1 (20.Kf2 Nxd4) 20...Qc2 and 21...Nxd4. 41...Bh2 allows White to play 42.Kc4. Perhaps Black can draw with 41...Kb5. 44...Kc7 allows 45.a6 and 46.Kb6 for the win. But can Black draw by moving his bishop instead?
   Aug-05-17 K S Ojanen vs G Barcza, 1936
wwall: I think White missed a win with 30.Bf8! If 30...Qxf8??, then 31.Qf3 (threatening 32.Qa8 mate) 31...Kb8 32. Nd7+ winning the queen. If 30.Bf8 Qd8, then 31.Qe4 (mate threat) Kb8 32.Bxb4 wins a piece.
   Aug-04-17 Larsen vs Laursen, 1950
wwall: Instead of 26.Bf4, perhaps stronger is 26.Rd8 to get the rook out and aiming 27.Bf4. Instead of 40...Ba4, which allows 41.d5, doesn't 40...Ke6 draw with opposite colored bishops?
   Aug-04-17 L A Tan vs Alvarez, 1963
wwall: Instead of 31. Kh3, perhaps best is 31.Nxe5 dxe5 32.Bc5 Re8 33.Bd6 and 34.Bxc7. 34...Nd8?? looks like the losing move. Black had to find room from the queen to move, so perhaps best is 34...Rf8 and if 35.Ba7, then 35...Qd8.

Apr-16-11  Open Defence: breaking news!! Bill Wall + Open Defence draw against Rybka!! :)
Premium Chessgames Member
  wwall: I think it was Houdini we played, run by Aylerkupp. We had Black. With the help of Hosea, we got a draw (drawn endgame as we sacked our knight to get into a knight vs pawn ending).
Apr-16-11  Open Defence: i thought Wilson said GE and AK switched engines and kutz just posted his stockfish game against houdini, so my guess we drew with rybka.. though i am very confused at the line up change
Apr-16-11  Open Defence: the yahoo game score emailed to me is in a very poor format will wait for AK to post the PGN

Premium Chessgames Member
  wwall: <chessmoron>. I have no problem on the May date, but now I have a conflict for next week, April 30. I am playing in the Space Coast Open in Cocoa, FL with round 1 at 10 am and Rd 2 at 1 pm. I don't think I can make the 12 noon start time for EST. Can a replacement be found for me or can Hosea and Eric play if Eric makes it?
Apr-23-11  Open Defence: does Sunday 1 May 2011 work for you Bill?
Apr-23-11  chessmoron: <1 May 2011> won't work for <kutztown> though.

Would April 29th work for you <wwall>?

Premium Chessgames Member
  wwall: Friday, April 29 would work for me if it is in the evening EST. On May 1, my rounds are at 9 am and 2:30 pm. I would be ok in the evening.
Apr-23-11  chessmoron: 10:30 pm EDT Friday on April 29th? (That 8 am Saturday in India). If that doesn't work for you, Thursday, the 28th at the same time?

  Golden Executive: <chessmoron> <April 30-Round 3

Stockfish-Rybka 4 >
I (Houdini´s operator) have no problem playing at Sunday May 1 or Friday 29. I have problem thursday 28

Premium Chessgames Member
  wwall: 10:30 pm EST works perfectly for me on Friday (Thursday also works)
Apr-23-11  Open Defence: just read the comments to the rybka game at,

I dont think the average chess fan understands how much of a handicap no Opening books and no Tablebases are to an engine

it still takes a lot of work to go the distance against an engine but with opening books and tablebases the engines would gain and exploit advantages in record time

so the guy who posted that rybka must have been handicapped was in a sense right that it was handicapped with no opening book or tablebase but not otherwise in handicapped in any way..

wonder what they will say for the stockfish game especially since it was a tactical shot that got the draw!
