Re: 62 test positions from last couple of months

I do not think the answer is clear yet, but my guess is that Bg5 is actually better than Bg7: 4r1k1/1r1np3/1pqp1ppB/p7/2b1P1PQ/2P2P2/P3B2R/3R2K1 w - - acd 51; acs 900; bm Bg5; c3 "Bg7"; ce 343; id "ERET 084 - Koenigsangriff"; pm Bg5; pv Bg5 Nf8 Qh8+ Kf7 Rxd6 Qc5+ Kg2 fxg5 Rh7+ Nxh7 Qxh7+ Kf8 Qh6+ Kf...

Re: Leela is doing well in TCEC season 14, +90 elo above SF

Error bar is +/- 154 Elo.
But it does appear to be playing very well.

I do not have a problem with someone getting excited over something new.
I do that myself all the time.

Re: To analysis.sesse.net owner : disable contempt

There are two different issues at play. Contempt causes weird scores, especially when the score is close to zero. There is also the stockfish "sewing machine" effect, which has been partially cured, but sometimes raises it's ugly head. So I have a setting to turn both of those things off. This one ...

Re: Queen vs 2 Knights

The bizarre magic of positions like these comes from 6 or less men on the board.
In fact, even when there are more than 6, an engine that is behind may try to reduce the board to 6 men so that a known draw position can be forced.
