Re: The Bryntse Gambit

One more iteration. Now Bh3 is preferred: -1.74 14. Bh3 Bxe5 ... 53. Kd2 Kxe6 (depth 61, 10:21:06) the final position in the 14. Bh3 line is a draw. While SF says -1.74. AB game rollouts to evaluate this gambit are not reliable. I haven't seen it yet, but the very end of the line won't be reliable....

Re: The Bryntse Gambit

e.g. Stockfish-dev prefers Bf5 to Bh3: -1.58 14. Bf5 Rf8 (depth 56, 8:04:21) -1.83 14. Bh3 Bxe5 (depth 56, 8:04:21) The difference in eval. here is pretty small too, even though it's gone to depth 56. Depth 60 now. I agree with Dann; this gambit is a loser for White. -1.83 14. Bf5 Rf8 15. Bg6 Qe6 1...

Re: The Bryntse Gambit

There is a very similar line. This line is more sound for white. Why do you think it's more sound? The different Black pawn placement doesn't make SF (at low depth) like it any more than the first line. Well, K13.01 held against latest brainfish. I remember that in the original line, K almost alway...

Re: The Bryntse Gambit

I also tossed in Sting: rn1qkb1r/pp2pppp/8/2p3N1/2B1pPn1/8/PPPP2PP/RNB1K2R w KQkq - acd 40; acs 43177 ; acn 599380716k; ce -165 ; bm Bxf7+; pv Bxf7+ Kd7 Be6+ Kc6 Bxg4 e5 Nf7 Qe8 Nxh8 exf4 Nc3; I say put a fork in him (Bryntse), he's done. I would love to be wrong, because it's wonderfully quirky. B...

Re: Komodo 13 released

~snip~ The scores reported by an MCTS engine like Komodo MCTS already reflect the possiblility of the opponent going wrong in plausible ways. Maybe it doesn't do it the same way you would, but at least to a significant degree it does what you want. That's really interesting. If this is possible wit...

Re: The Bryntse Gambit

Game 1 Done. I think Leela may have lost the draw around move 54, but Stockfish always thought it was winning. Oh well what do I know? :lol: [Event "40 Moves in 120 min; 20 Moves in 60 min;"] [Site "Engine Match"] [Date "2019.05.13"] [Round "1"] [White "Lc0 v0.22.0-Dev-JH.T8.610 4 Th"] [Black "Stoc...

Re: Opposite Color Bishop Endgames

That just means it has a high Elo. Like I pointed out high Elo and 'good at chess' are entirely different things. LC0 and Stockfish are recognised as the best chess playing entities in the world. What part of comparative and superlative grammar do you not understand? good - better - best If they ar...
