Ron: I personally knew Albert Chow in the 1990s--I said as much in a post in 2004. I'd wondered if Albert Chow was still playing chess. There's evidence that his most recent rated game is from 2017. https://old.chesstempo.com/gamedb/p... Below is one of his games not in this database. ...

Ron: <plang: The first book included 80 games from 1983-94. If the new book only includes 10 games from the earlier volume then how could this new book be his "100 best games"?> Amazon's search inside feature is great. It shows as the following Chapters from Timman's new book: ...

   Oct-03-20 A B Arnold vs Chigorin, 1885
 
Ron: Here is some non computer analysis: After 26. .. Bc5!, if White played 27. hxg4 then 27. .. Qh4 mate The queen sacrifice 29. ... Qxg2! leads to mate. If instead White had played 31 Kg3, then 31. ... Bg2 mate

Ron: <AylerKupp> Thank you for the informative posts. I'm wondering if there are any programs that use Monte Carlo Methods. I hypothesize that a program using Monte Carlo methods on the position would give a zero or near zero evaluation. I heard that there's "Rybka Randomizer".

   Sep-08-20 C G M Watson vs D Marotti, 1922
 
Ron: I came across this game from the Random Game feature. White's 39th move is a blunder, for the winning advantage that White had could have been entirely vaporized by Black. Stockfish 11 gives instead: 39. ... Rxc7 40. Rxc7 Qf6 41. Qxb7 Nh2 42. Rxh7+ Kg8 43. h6 Nxf1 44. Rg7+ Kh8 45. Rh7+ ...

  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. =)

  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.

  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

Jul-31-19  gambitfan: Can we trust Stockfish ?
In the Opening Explorer, after 1 e4 e5 2 Nf3 Nc6 3 Bc4 Nf6 4 0-0 d6 5 d4 ?! (2 games · 1871-1949) the Opening Explorer gives 5 ... exd4 (126 games) or 5 ... Nxd4 (1 game)

Stockfish gives :

1) -0.42 (18 ply) 5...♗xd4 6.♘g5 ♘h6 7.c3 ♗b6 8.h3 O-O 9.♘f3 ♘a5 10.♗d3 ♗e6 11.♘a3 ♘c6 12.♘g5 ♗d7 13.♘c4 ♔h8 14.♘xb6

On chess.com this move is said as an INACCURACY...

What can we think of Stockfish ???
