Ron: <tpstar> wrote in part: ".<.. People noticed 17. Ke3 as a quaint computer move >" and "<...but I'll bet 100 out of 100 humans would automatically choose 16. Nxd2 followed by 0-0, making AlphaZero's 16. Kxd2!? and 17. Ke3 quite inspired...>" 1. I haven't seen anyone ...
 
   Sep-14-18 Radjabov vs Ivanchuk, 2013
 
Ron: I commented on this game when it was in progress. I had called 15 Rd3 by Radjabov a "genius" move. Stockfish 9 doesn't evaluate it as highly though. After 15 Rd3 it gives: 15... h6 16. Rbd1 Nd7 17. Rd6 Rf6 18. Rxf6 Nxf6 19. gxf4 Nh5 20. fxe5 Bg4 21. Bc1 Bxf3 22. Bxf3 Qxe5 23. Bg2 Rf8 ...

Ron: After 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f3 O-O 6. Be3 e5 7. d5 c6 8. Bd3, 8. .... b5 is the move made by Stockfish 9. However, instead of 9. cxb5, Stockfish 9's choice is Nge2

Ron: Daniel Freeman left a fine legacy. R.I.P. With the two founders of this website deceased, alas, who is in charge of this place?
 
   Jul-28-18 Mackenzie vs Blackburne, 1890
 
Ron: It was a pleasure to go through Mackenzie's play in this game. Notice that the knight was stronger than the bishop in this game.

Ron: <zanzibar: Yes, we all agree on this. I've tried writing an AlphaZero member to get the additional games, but he begged me off citing a pending submitted article's publication.> If I worked for Google, I would consider copying the games and giving it to Wikileaks. ...
 
   Jun-16-18 Kramnik vs Leko, 2004
 
Ron: I just came across a video analysis by GM Varuzhan Akobian of this game. I found it instructional and I found its perspective, years after this game was played, interesting. https://www.youtube.com/watch?v=o36...
 
   Jun-03-18 W So vs Carlsen, 2018 (replies)
 
Ron: 21. .. Qe8 is a sub optimal move according to Stockfish 7

  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
