Re: LC0 bad search and poor tactics

You’re moving goalposts and everybody sees you doing it. NNs are bad tactically. Agreed. Thx, appreciate the insight.

Re: Interesting game (Caro Kann, Advance)

Qg4 is a NN move imo...current leela (t30) disfavors it and thinks black is fine until Rxg2, giving white winning chances.

Even stockfish 10 on a single core i ran alongside leela takes quite some time to even discover, much less reject, the ideas here: FEN: rnbqk2r/ppp2ppp/4p3/8/1bBPn3/2N2N2/PP3PPP/R1BQ1RK1 b kq - 1 7 Lc0 T30: 14/30 00:00.036 56k 5k +0.35 7. ...

Re: Why Lc0 eval (in cp) is asymmetric against AB engines?

I think that’s the major factor, especially at this TC, but “comtempt” (relatively dramatic cp scores) also plays a part...when possible I exclusively use win% with leela now because after a short time you can understand her evaluation in traditional “+-, +/-, +/=“, etc terms. If the cp value is int...

Re: King Solomon's position, again (Andscacs & Houdini)

leela eventually comes up with a very interesting take on the last position, after stalling at a drawn position for awhile-- [d]r1b1kbnr/pp3ppp/2p1p3/3pP2q/8/2NP1N1P/PP3PP1/R1BQ1RK1 w kq - 0 1 g4!!? i leave it those with far more powerful hardware to check it's soundness...

Re: King Solomon's position, again (Andscacs & Houdini)

imo latest t30 net (32616) doesn't suggest it's winning, only best, hovering around 65% (which should prob be something like a half pawn+ rather than a full pawn) & not climbing by the end of my search: FEN: r5k1/1ppq1bp1/2n4r/1BBn1p2/p1NPp2p/P3P1P1/1PQ2P1P/2R3RK b - - 0 1 Lc0 T30: 1/2 00:00.028 4 1...
