   Jun-18-22 Ding Liren vs Nepomniachtchi, 2022

Ron: <saffuna: What was wrong with 13. Bxe4 ?> Saffuna is right. Chessgames.com's computer, at 4 fuel, gives: 1) +0.71 (24 ply) 13.Bxe4 Qh5 14.Nxg4 Bxg4 15.f3 Bh3 16.Rf2 Nc7 17.e3 Ne6 18.f4 Qxd1+ 19.Nxd1 a5 20.bxa5 Rxa5 21.d4 Bf6 22.Bd2 Ra7 23.Nc3 c5 24.d5 Bxc3 25.Bxc3 Nf8 26.Bd3 Rxe3 ...

Ron: Here is a position from a possible variation in a game I played. Black is down a pawn, black to move, yet there's a win for Black in 11 moves: [DIAGRAM] 31. ... Rxg3+ 32. fxg3 Qxf1+ 33. Kh2 Qxe2+ 34. Kh3 Qf1+ 35. Kh2 Rf2+ 36. Qxf2 Qxf2+ 37. Kh1 e4 38. g4 e3 39. g5 hxg5 40. a4 e2 41. a5 ...

   Jun-03-22 P Meister vs F Bindrich, 2010

Ron: 1. I found the solution. 2. Impressive attacking game by Peter Meister.

   May-15-22 Firouzja vs Dominguez Perez, 2022

Ron: Interesting game by Firouzja. Chessgames.com's computer confirms that 36. Rh7! is best.

   May-13-22 I Denisov vs Khalifman, 2011

Ron: While researching the 4 pawn attack against Alekhine Defense, I came across this game. After Black's 11th move, my Stockfish 15 gives +1.69 for White. An eval over 1.00 is usually winning. 12. Qb3 exd5 13. cxd5 c6 14. Bxa6 bxa6 15. Bxb6 axb6 16. Rad1 c5 17. Ne4 dxe5 18. Nxe5 Bf5 19. Ng3

   May-13-22 Caruana vs Mamedyarov, 2022

Ron: After 21. Rf1 my Stockfish 15 gives 21. ... Qe6 with an about equal position. But 21. ... Na6 is a blunder, the eval jumps to + (2.54) Depth=40/72 0:04:00 151 MN with 22 Be5!

   Apr-16-22 Honza Cervenka chessforum

Ron: Here is game with a Missed Chance by Tarrasch: Mackenzie vs Tarrasch, 1887 A kibitzer gives computer analysis showing 24....Rxg2! wins. Before that move, Tarrasch's pieces are pointing in the surrounding area of White's king, and one might think that there has to be a successful attack

   Apr-01-22 Mamedyarov vs V Keymer, 2022

Ron: 12. g4 is an interesting gambit. Hopefully I'll get back to this game with the time to do analysis.

   Mar-23-22 Sergey Karjakin

Ron: This is from the news publication The Hindu: The Azov began as a military infantry unit made up of civilian volunteers drawn from far-right, neo-Nazi groups that were active in Ukraine, such as the Patriot of Ukraine gang and the Social National Assembly (SNA). With its highly ...

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 Café 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
