   Feb-19-17 F Visier Segovia vs J Betancort Curbelo, 1968
 
wwall: Looks like 25...Rxc2?? is the losing move, allowing 26.Be5 with mate threats. Perhaps best is 25...Qf3, and if 26.Be5??, then 26...Rxe5 27.Rxe5 Qxd1+ wins for Black. Besides 28.Rxg7, White could have won with 28.Rxc1 Rf8 (28...Rxc1?? 29.f8=Q mate) 29.Rcg1, threatening mate in a few ...
 
   Feb-18-17 B Kostic vs D Donaldson, 1915
 
wwall: Instead of 22.Ne4, White could have offered a queen sacrifice with 22.Rhf1 (threatening 23.Rf8+) 22...Rxg4 (22...cxd5 23.Nxd5 Rxd5 [23...Rxg4 24.Nxe7 mate] 24.Qf4 with a mate threat) 23.Rf8+ Qxf8 24.e7+ cxd5 and now four different ways to checkmate next move by queening either pawn ...
 
   Feb-16-17 V Soldatenkov vs NN, 1902
 
wwall: Instead of 28.Qg8+ white mates in a few moves with 28.Rdg1!, threatening 29.Qg8+ Rxg8 30.hxg8=Q mate. After 28.Rdg1, if 28...Rxh7 (28...Nf6 29.Qg8+ Nxg8 30.hxg8=Q+ Rxg8 31.Bg7 mate), then 29.Bg7+ Kg8 30.Bxe5+ Rg7 31.Qxg7+ Qxg7 32.Rxg7+ Kf8 33.Rh8 mate.
 
   Feb-14-17 B Kostic vs C Jaffe, 1911 (replies)
 
wwall: It looks like 92...Bg5?? is the losing move. Black should have played 92...f1=Q 93.Rxf1 Bg3 and it is a book draw. After 94.Rd4 Kxf1 95.Kxd2 (or 95.Rxd2) there is no win in this rook vs bishop endgame.
 
   Feb-13-17 Kupchik vs Capablanca, 1913
 
wwall: Perhaps the losing move is 42.Nd3 since White will not be able to protect the d4 pawn with his knight. Better may be 42.Kc1, and if 42...Rxh5, then 43.Rxb3 Rh4 44.Rf3 Kg6 (44...Rxd4 45.Rxf7+ Kg6 46.Rf8 looks like a draw) 45.Nc2 and White may be able to draw this endgame.
 
   Feb-12-17 Schwarz vs O Junge, 1905
 
wwall: Instead of 16.Nf1, better may be 16.Bd4 and exchange rooks, which now looks like in White's favor. 20.Kg3?? looks like the losing move as the king gets trapped and mated. White could try 20.Bxh7+ Nxh7 21.h3 and perhaps survived. Instead of 24...f6+, Black had a forced mate in two ...
 
   Feb-10-17 Fischer vs J Witeczek, 1964
 
wwall: Perhaps the losing move was 54...Bd5 since White has threats to fork bishop and king later on. Better may have been 54...Bc4 55.Ne6 Kf5 56.Nf8 h5. After 54...Bd5, White had 55.g4! h5 (55...h6 56.h5+ Kh7 57.Kxf6) 56.Ne2 Kg7 57.Ng3 hxg4 58.Nh5+ Kg6 59.Nf4+, which should win. In the ...
 
   Feb-07-17 Alekhine vs L Litov, 1915
 
wwall: It looks like the losing move was 30...Qa7. Black may be winning after 30...Ne7. In the game, after 31.Ba5+, better may be 31...Kb7 32.Qb4 f5, but White is still probably winning. In the game, Alekhine tries a rook sacrifice first with 32.Rxb5. If 32...cxb5??, then 33.c6 mate. Other ...
 
   Feb-06-17 Fine vs Keres, 1938
 
wwall: <Howard> The quote came from Martin Beheim in Chess With the Masters, p. 237. "Had Fine been the winner,it is quite possible that his American compatriots would have found the backing for a title match with Alekhine -and Fine would have had excellent chances against an Alekhine ...
 
   Feb-06-17 B Burt vs Blackburne, 1869
 
wwall: Why is this B. Burt? This was John Norman Burt of Bristol according to several sources (including Gaige). Also, it is not a forced mate in 9 moves. White could have played 14.cxd4 instead of 14.Qb4+ and no forced mate in 6 more moves (mate in 20 more moves instead). White has a forced

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

  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?

  chessmoron: <1 May 2011> won't work for <kutztown> though.

  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 chess.com,

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!
