   Nov-30-19 Vassily Ivanchuk

Ron: Here is a recent beautiful game by Ivanchuk, which is not in chess games.com's database yet: https://www.youtube.com/watch?v=mNF...

   Nov-29-19 Tal vs D Sansom, 1964

Ron: <StupidQuestion: Should black have gone for 16. ...Nxc4?> My Stockfish gives after 16. ...Nxc4 a line in Tal's style: 17. Nxc4 Rxc4 18. Bxg6+ hxg6 19. Qd3 Qb5 20. Qxg6+ Ke7 21. Bh4 Rxh4 22. Nxh4 fxe5 23. Nf3 exd4 24. Ne5 Kd8 25. Nxc4 Qxc4 26. Rxa7 Qc8

   Nov-29-19 Kashdan vs Forbes, 1930

Ron: I found this game with Sacrifice Explorer. 27.Nxg5! is sound. After 27. Ng5 fg5 28. Bg5 Bg5 29. Qg5 Kf7 30. Qd8, Black did not play 31.... Na8 for Black would lose his rook after 32. Qxd6. The combination starts with 27. Nxg5! and by the end of move 35, Isaac Kashdan is up a pawn and ...

   Nov-29-19 AlphaZero (Computer)

Ron: <keypusher: A0 strikes again: <https://www.reddit.com/r/chess/comm...> Thanks for bringing this to our attention. I read the BBC article. The human race is doomed, I tell ya, doomed! Just kidding. I think it is an overreaction by the Go master to retire. AphaZero hasn't ...

   Nov-29-19 Lipschutz vs Showalter, 1892

Ron: I came across this game from the Random Game feature. 25... Bc6 is a blunder, for Black makes his own rook trapped. After 26. Nb3, there is no safe square for the rook at c5 to go to! White wins the exchange.

   Nov-29-19 Reuben Fine

Ron: I wonder if Reuben Fine had any psychoanalytic patients who were chess enthusiasts. I think it would be pretty cool if Reuben Fine discussed chess with his patients.

   Nov-23-19 Steinitz vs J C Halpern, 1894

Ron: I came across this game by one of my chess heroes--Wilhelm Steinitz--via the Random Game Feature. After White's 21st move, Black's game is so constricted that he is going to lose his bishop at c7. With 26. Nxe6! White threatens mate with Ng7. Stockfish gives better moves for White and ...

   Nov-23-19 Olland vs W A T Schelfhout, 1921

Ron: I came across this game from the Random Game feature. 20 Nxf7! is sound. Stockfish gives a better defense for Black, nevertheless White has a material advantage: 20. ... Bxf7 21. Bxd5+ Be7 22. Bxf7+ Kxf7

   Nov-23-19 Kibitzer's Café

Ron: This is from a variation in a game I'm involved in: [DIAGRAM] White to move. There is a forced mate in 9 moves: 31. Nxf5 exf5 32. Rg3+ Kh8 33. Qe5+ Kh7 34. Rxf5 Rd7 35. Rxf7+ Rxf7 36. Qe4+ Kh8 37. Be5+ Rg7 38. Rxg7 a4 39. Rg3#

   Nov-10-19 Honza Cervenka chessforum

Ron: Here's a suggested game for your Missed Chances collection. Zukertort's sacrifice was not sound; his opponent missed the one move that refutes it. Zukertort vs W A Lindsay, 1874

Oct-06-08		tpstar: <Ron> I am very much enjoying your Game Collection: Games Involving Queen Sacrifices and have already found several excellent examples to use as puzzles, for my students along with our state magazine and another chess site. Note your latest diagram has 2 Black h Pawns. =)

Oct-06-08		Ron: Thanks <tpstar> I will update the diagram anyway. I created the game collection of queen sacrifices before sacrifice explorer was created I think, so I went by games I knew about and came across here.

Jan-16-10		I play the Fred: Ron, if you are interested in adding to your Queen sac collection, have you seen Andruet-Spassky 1988 before? It reminds me a bit of Lewitzky-Marshall.

Mar-23-10		Honza Cervenka: Hi Ron, I don�t know whether you have read my recent messages at Kibitzer�s Caf� or not and so I am posting it here too. On Monday of last week I have become proud father of (the second) daughter named Aneta. You can see her picture on the site of regional newspaper �Kladensky denik� (Kladno�s Daily) at http://kladensky.denik.cz/miminka/m... where is just now till this Friday (12:00 A.M. CET) running a polling contest for the most sympathetic baby born last week in regional maternity hospitals organized by the newspaper. Personally I am not much interested in such a kind of competitions but my wife likes it very much and she would be much happy to see our little girl on the top. Right now we are on the second place in very tense and close race with two other contenders and so every additional vote is very important for the final outcome. If you would like to help me to make my wife even happier than she already is now, just click on the link above, flag �Aneta Cervenkova, Stredokluky� (the first name in gray box on the right side on the screen) and hit the �hlasovat� button below. It is possible to vote repeatedly always after 60 minutes from one IP address... :-D Thanks and warm regards, Honza
