Re: Is the Latvian losing?

Here is some data for the Latvian Gambit: I don't think those are all Latvian positions, for example: rnbqkb1r/ppp2ppp/4n3/3pP3/8/3P1Q2/PPP3PP/RNB1KBNR w KQkq - Black apparently hasn't played .. f5. But your comment about the opening is valid. A lot of the entertaining positions for Black are in li...

Re: SSD SATA Recommendation

Samsung 860 PRO and 860 EVO series are good in my experience. M.2 drives are faster though (Samsung 970 series).

Re: Sargon 1978 - Bringing it back to life

The github docs say in a couple places it has a "full width" search, but it also mentions "minimax." The latter term usually indicates the alpha-beta algorithm but I am not really clear from the description whether Sargon implemented this. The basics of the algorithm go back to Shannon's 1950 paper,...

Re: Sargon 1978 - Bringing it back to life

Back around that time I did a lot of Z80 assembly programming, although not chess. I wrote a complete word processor in assembly.

Re: On-line engine blitz tourney May

I use icsdrone (https://github.com/DrRibosome/icsdroneng). This has native UCI support. The only complication with that is that it is really designed to run an engine on the server automatically, without any intervention by the engine owner. For tournaments though you either need to be able to comma...

Re: On-line engine blitz tourney May

"some "training" server that I can use" The best thing probably is to log into the nightmare-chess.nl some time before the tourney - there are usually a few engines logged in there and you can try playing a few games with them. Alternatively, you can try your engine on FICS (freechess.org). It is t...

nice sac from FIDE Nations Cup

Yu-So, FIDE Chesscom Online Nations Cup (11) 2020. Yu played Ng5+! Not too hard for Stockfish but not trivial either.

Re: front-ending

I think what ought to be done is to merge the Winboard/Xboard protocol and the UCI protocol and have a single formal grammar for them. Then the client and server parts of chess programming would be a snap and nobody would have to furrow their brow over it. That's a fine idea, but they are incomplet...

Re: Carlsen is leading the Online Invitation LIVE

Carlsen won this - he played solidly in the final, and got to demonstrate his fine endgame technique. Nakamura is one of the very top rapid/blitz players, so winning against him is an achievement.

Re: Carlsen is leading the Online Invitation LIVE

I was pretty amazed the other day when Carlsen played the King's Gambit (as White) and then the Scandinavian .. Qa5 (as Black) against Ding Liren. He lost both games. These are not top-level openings: as a GM, you might use them as a surprise weapon, but a super-GM like Ding is hardly going to be su...
