Re: How does your stockfish evaluate this position at move 24!White turn!

I checked again. MultiPV shows the following: 24/41 +2.00 Rd2 Re1 Bg4 Kg2 Rc2 e5 Bxf3+ Kxf3 Rxc3+ Kg2 Re3 Kf1 Rxe5 Bf3 Rf5 Kg2 Kg7 Re2 Bd4 Rd2 Bf6 Rc2 Re5 Rc6 Ra5 Bd1 Rd5 Be2 Rd2 Kf3 Bd8 Kf2 Kf6 Kf1 24/39 +1.40 Bxf1 Rxf1 Rd2 Bb5 Kf8 Rf3 g5 h3 Rc2 e5 Rc1+ Rf1 Rxc3 Be2 g4 hxg4 Rxg3 gxh5 Re3 Bf3 Rxe5 ...

Thanks for the Cfish line, but I checked it and SF Dev shows around +2.xx in advantage after 30.Rf3 there's 30...Rd2 and SF prefers black at this point.

You've confused the colors. 30...Rd2 loses for Black.

Re: Minimalism in chess programming

I'm close to complete my minimalist engine. After implementing alpha beta prunning and the most basic move ordering stuff I've finally reached the point of satisfaction. My original aim was to masrter 0x88 board representation( previously I tried mail box 120 and plain magic bitboards believe it or...

Re: Chess.com 2018 computer chess championship

[ That jump assumes that all engines have NUMA support. It is my understanding that only Stockfish, Houdini, Texel, and Ethereal have such support. I'm tempted to add Komodo into that too, based on some chats with Mark, but I don't know that first hand. The key to decent NUMA support is to have eac...

Re: Beautiful game, highlights strengths of NN+MCTS

Another beautiful game. Here, a strong SF derivative Andscacs outplayed in endgame because of an immobilised Kf1. NN+MCTS giving up material in exchange for its K mobility. Looks like SF Dev version is having a difficulty finding the excellent continuation 33...Rd8 on the below diagram. [Event "Lc0...

Promoting into a rook,
The under-promotion to a rook is elegant, but what's really lovely is the king walk from h1 to a1. It's this fascinating maneuver that allows White to secure a draw by repetition, even though he has only a two rook material advantage.

Brilliant game!

Re: Kornrade Test

Hi Louis! Pretty study! Fishing Rod is the easiest one for engines, I guess, Hi Peter, I chose to start with Fishing Rod . . . simply because I was intrigued by the name! Was happy that Stockfish solved it, but now you've warned me that other solutions will be hard to come by. Might return to these...

Would this position would be covered by the tablebase with white having 6 pieces and black having 8?
No. Current endgame tables are for no more than 7 pieces total, including both kings.
