14. Kf1 is claimed to be "One of The Deepest Moves Ever Played in Chess"

I could only find a draw at best with 14.Kf1.

My analysis shows amazingly that Bd2! is winning.

Re: Huge SF 11 test with 7 different Contempts

But -15, -24 and -40 are much better against LC0. What contempt do you recommend? Right now the best Stockfish in no match for the best Lc0 T61. In my testing. I haven't tested it enough but I think the best contempt for Stockfish vs LC0 is somewhere between -30 and -100. Even if LC0 wins the match...
