I live in Palm Bay, Florida. Retired Air Force officer (1970-1995). I work at Harris Corporation as a senior systems security engineer on a program called GOES-R for NOAA and Satellite Antenna Systems for the National Weather Service. I've written a few books and articles on chess miniatures, irregular chess openings, and chess trivia.

Some of my games and short bio here Bill Wall - White Knight Review magazine I wrote - Russian Wiki (not notable enough for US Wiki) - my old chess webpage (2009) - index of my chess articles

   Dec-11-14 E D'Andre vs E Rousseau, 1867
wwall: After 28...gxf6, White missed a forced mate in 4 moves or less. Instead of 29.Nxf7+, White can play 29.Rfc2, threatening 30.R2c7 and 31.Rd7 mate. After 29...fxe5 30.dxe5+ Ke7 31.R2c7. After 41.Rd6 Kxe5, White can play 42.Rbc7 Nd6 43.Re7+ Kd4 44.Rxd6 and mate in a few moves after ...
   Dec-08-14 M S From vs S Rosenthal, 1867
wwall: Instead of 43.Qxc7, White has a draw after 43.Qh8+ Kg5 44.Qd8+, etc (44...Kf5 45.Qxc7 or 44...Kh6 45.Qf8+ will be perpetual check, or 44...f6 45.f4+ Kf5 46.Qc8+). After 43.Qxc7 Qe2+ 44.Kh3?? loses right away. White should at least try 44.Kg1 Qxf3 45.h4 and perhaps a draw. After ...
   Dec-04-14 Steinitz vs De Riviere, 1867
wwall: After 23...Rf8, instead of 24.Bxe6+, White should have played 24.Rxe6 Rxe6 25.Bxe6+. After 24.Bxe6+ Black should play 24...Kb8 to avoid a check after 24...Kc7 25.Nb6 and 26.Nxd5. After 24...Kc7, White should have played 25.Nb6, threatening 26.Nxd5+. Instead, White played 25.Rd2. Now ...
   Dec-02-14 Winawer vs M S From, 1867
wwall: Instead of 17.h3?, which allows 17...Qf6!, perhaps best is 17.Bh7 Kf8 (17...Kh8? 18.Nxf7+ forks king and queen) 18.Nf3 Qf6 19.Ne5, which should hold. White is now probably better. After 28.Rxf7, instead of 28...Bc5, Black could play 28...Kg6 29.Ree7 Bd4 and 30...Kxg5 for the win.
   Dec-01-14 H Czarnowski vs Steinitz, 1867
wwall: 55...Rxg7? should have lost. Instead of 56.Ra6, White can simply play 56.Rxg7! After 56...Kxg7 57.Ke3 Kf6 58.Kd3 Ke6 59.Kc4 Kd6 60.Kb5 Kc7 61.Ka6 Kc6 (61...c4 62.bxc4 Kc6 63.a4 Kc7 64.Ka7 Kc6 65.Kb8 wins) 62.a4 Kc7 63.Ka7 Kc6 64,Kb8 b5 65.a5 and 66.a6, 67.a7, 68.a8=Q wins for White.
   Nov-26-14 Suetin vs Spiridonov, 1975
wwall: After 20.Qg3, if 20...Nbd7?, then 21.hxg6 fxg6 22.Ne6, threatening the queen and playing 23.Nc7+ and 24.Nxa8 next. 20...Qe7 prevents that, but after 21.hxg6 hxg6 22.Qb3! and White wins.
   Nov-21-14 L B Hansen vs M Matthiesen, 2007
wwall: After 26.e4!, White threatens 27.Qb3+ Kh8 28.Rxf8 mate. 26...Qe6? looks like the losing move. Best may be 26...Rxc8 27.Rxc8+ Rd8 28.e7+ (or 28.Qb3+ Kf8) 28...Kg7 29.Rxd8 Qxd8 30.Nd5 Nc6. After 26...Qe6? 27.Qg4 threatens 28.Nh6+, winning the queen. If 27.Qg4 Qxa2, then 28.Rxf8+ Kxf8 ...
   Nov-20-14 Averbakh vs E Bebchuk, 1964
wwall: After 49...Kxb5, if it were Black's move again, he would win after 50...Kc5. 51.e5! wins. If 51...Kd5, White gets a protected passed pawn after 52.e6 Kd6 53.Kc4 Kc6 54.Kb4 b6 55.Kc4, and White wins. After 52.g5, White wins after 52...Kd6 53.f6 Ke6 54.fxg7 Kf7 55.gxh6 b5 56.Ke4! b4 ...
   Nov-20-14 Baburin vs J Ryan, 1996
wwall: Nice miniature. White threatens 25.Qg7 mate. If 24...gxf5 (24...Qxh6 25.Nxh6+ and 26.Rxe1), then 25.Qxh1 Rxh1 26.Rxh1 and Black is down a piece.
   Nov-19-14 G Abrahams vs W Winter, 1946
wwall: 30.Bf8!, threatening 31.Qg7 mate, was strong. This is better than 30. Ne7+ Rxe7 31.Qxe7 Qc1+ 32.Kh2 Qh6+ 33.Qh4 (otherwise perpetual check) Qxh4+ 35.gxh4, which looks like a draw. After 30.Bf8, if 30...Kxf8, then 31.Qh8 mate. If 30...Rxf8, then 31.Ne7 mate. If 30...Qc1+ 31.Kh2 and now

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

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!
