   Feb-26-15 Mohishunder vs Cochrane, 1855
wwall: After 55...f4, White looks like he can draw after 56.Rc8! and Rg8+. Instead, he played 56.Kh2? and Black wins after 56...Kg4.
   Feb-25-15 Valenciennes vs Douai City, 1837 (replies)
wwall: The rest of the game should be 52.Nxe5 Kd6 53.Kd4 g3 54.Nf3 Bxb3 55.Ke3 Bd1 56.Nd4 Kc5 57.Nf5 g2 58.Kf2 e4 0-1

wwall: Brian Williams will be replacing Jon Stewart for 6 months. Brian Williams works for Kaspersky Labs and expects to earn more than his old $10 million a year with his new job as bank consultant. Brian Williams was a sniper for SEAL Team 6 and trained the Beltway sniper. Brian Williams ...
   Feb-14-15 Aronian vs Kramnik, 2015
wwall: Instead of 59...a5, perhaps 59...Kd5 has a good chance of winning. If 59...Kd5 60.Nd4 b4 looks like a win for Black. If 60.Ke2, then 60...a5. If 60.Ne1 Ke4 61.Nc2 f3 62.Ke1 Kd3 should win.
   Feb-14-15 Aronian vs Karjakin, 2015
wwall: It looks like after 45...Ng4 (45...Nf3 looks better), White traps the knight after 46.Rh4. If 46...e3, not 47.Rxg4? Bf3+, but 47.Nd3+ Kd6 48.Nf4, threatening 49.Rxg4.
   Feb-09-15 R Makhmutov vs A Shimanov, 2015 (replies)
wwall: It was a draw until 80...Ba3??. Black needs to keep the bishop on the long diagonal. Now 81.Kf6 Bb2+ 82.Kg6 and White captures the bishop or threatens mate next move after the rook moves.
   Feb-07-15 A Muzychuk vs A Walton, 2015
wwall: 88...Kf7?? loses. 88..Kf8 or Kh8 or Kh7 draws.
   Feb-07-15 M Codenotti vs R Felgaer, 2015
wwall: Tough endgame. 63.Rh8? (63.Rb8 through e8) loses after 63...f3+!, but Black doesn't find the move. Black had chances to win with f3 on move 64, 65, and 74.
   Feb-06-15 M Marin vs A Minasian, 1992
wwall: 59.Ra3? draws. White wins after 59.Rd3! Nc3+ (59...Nf4+ 60.Kxe3 Nxd3 61.Kxd2 and 62.a7 and 63 a8=Q) 60.Kxe3 d1=Q 61.Rxd1 Nxd1+ 62.Kd2 Nc3 63.a7 and White queens his pawn to win.
   Feb-06-15 Karpov vs Timman, 1990
wwall: Soltis (Grandmaster Secrets: Endings) says that White has good winning chances after 28.Kf3 (instead of 28.f4) 28...f5 29.Ke3 e5 30.Nb5 Kf6 31.Kd3 followed by 32...Kc4. One winning line may be 31.Kd3 Ke6 32.Kc4 Nb6+ 33.Kc5 Nd7+ 34.Kc6 a5 35.Nc7+ Ke7 36.a4 h5 37.b4 axb4 38.Nd5+ Kd8 ...

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!
