   Jun-28-20 AlphaZero vs Stockfish, 2018
 
Ron: After Black's 179th move the position was King and Queen vs King and Queen yet the computers were allowed to play to move 229. There are positions when King and Queen vs King and Queen can be won, see for example: https://www.quora.com/How-do-you-wi... but such wins occur in 1 or 2 ...
 
   Jun-20-20 Kashdan vs Forbes, 1930
 
Ron: I just noticed something about this game which I missed when I kibitzed on Nov 29, 2019. Kashdan does a sequence of moves that were done by Morphy before him, and by Fischer after him: 1. Move the castled king to the rook file 2. Move the rook to the knight file, the square that was ...
 
   Jun-20-20 Raymond Keene (replies)
 
Ron: Raymond Keene in his latest essay says that he met the great writer Jorge Luis Borges: https://www.thearticle.com/two-ques... Unfortunately I don't have a Borges anecdote. Borges visited the Chicagoland area in the early 1980s. I was a kid back then, I had no awareness of Borges. I was
 
   Jun-07-20 Topalov vs Aronian, 2006
 
Ron: I had Stockfish 11 analyze after Black's 17th move. Would Stockfish play the exchange sacrifice like Topalov? For the first split second Stockfish 11's first choice was Topalov's move 18. RxN. Then it favored Bb2, then favored Ne5, then favored Qc1 18. Qc1 Bf6 + (0.29--) Depth=37/59 ...

Ron: alexmagnus: <The 1948 WCC was directly caused by the death of Alekhine, but even if he hadn't swallowed the bread crumb, there were strong voices after WW2, who wanted to take the title from him because of his Nazi-articles.> At the time of Alekhine's death a match between him and
 
   Apr-03-20 Levon Aronian (replies)
 
Ron: This is a terrible time for Levon Aronian and if he wishes to take a break from chess, I can absolutely understand. I hope that Levon Aronian doesn't retire from chess right now. I think that there are still great games left in him.

   Feb-13-20 Topalov vs Kamsky, 2006 (replies)
 
Ron: I remember going over this game soon after it was played. This game exhibited the 'exchange sacrifice' which was part of Topalov's playing style at the time. After over 13 years, what does computer analysis say? On move 26, instead of Topalov's 26. e6, Stockfish 9 gives 26. g4 hxg4 + ...

  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.

  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

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 ???
