   Jun-12-21 Spassky vs Fischer, 1992

Ron: Here's a possible example of Fischer yielding: In the tournament he participated by teletype, he thought his opponent played D4 and thus played Nf6. But his opponent had played E4. Fischer, instead of making an issue about it, continued playing the Alekhine opening. Still, I don't think

   May-23-21 Robert James Fischer

Ron: This past February someone uploaded on YouTube a clip of Bobby Fischer on the Johnny Carson show. https://www.youtube.com/watch?v=Qxv...

   May-22-21 Daniil Dubov

Ron: <coxscorner: Says in the bio that his chess coach describes his style like that of Tigran Petrosian, perhaps when he was younger, but in the last 2 years his play has become much more enterprising and aggressive. I don't think he plays anything like Petrosian. Any thoughts on ...

   Apr-28-21 Nakamura vs A Tari, 2021

Ron: With 24. Na5! Rd4 25. Nc6, Nakamura sacrifices his bishop for two pawns, and gets two passed pawns. Stockfish 140820 says Nakamura was correct with 24. Nxa5: + (3.88) Depth=42/85 0:01:05 82 MN

   Apr-08-21 Capablanca vs H R Bigelow, 1922

Ron: Instructive endgame by Capablanca.

   Apr-03-21 AlphaZero vs Stockfish, 2018

Ron: After AlphaZero's 71st move, AlphaZero has a one pawn advantage. However, it appears that Stockfish drew this endgame with precise lay.

   Apr-03-21 AlphaZero vs Stockfish, 2018

Ron: The King's Indian Defense: Saemisch Variation was the preset opening for this game between AlphaZero and Stockfish. I find interesting that at various points in the endgame, material was equal, but it appears that AlphaZero had an objectively won position. Winning this endgame required ...

   Mar-13-21 Hebden vs P J Batchelor, 2017

Ron: The position after the 38th move is an presented as an endgame problem here: https://en.chessbase.com/post/cbm-j... Hebden played 39. Ke5! and subsequently played correctly. Notice that in this end game problem, the winning side is at a material disadvantage, down two pawns.

   Mar-13-21 Wei Yi vs Giri, 2016

Ron: The position after 31. .. g5 is given as a endgame problem here: https://en.chessbase.com/post/cbm-j... Yi played 32. Kf3 here. After over 2 minutes of analysis, my Stockfish 140820 arrived at 32. c4+! Stockfish favored Kf3 for about the first two minutes of analysis. What could happen

   Feb-28-21 Levon Aronian

Ron: <karban: I don't get financial reasons at all. Levon Aronian has won quite a lot tournaments in his life, could attract sponsors. Should be wealthy man, just from private money, I don't know how much he got from a state, if so. The fact that someone gives you extra money should not ...

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
