Re: Knight equals 48 pawns?

But they are about 14 times as much as they should be. According to who? I think it is fairly common for Lc0 to report scores in the balllpark of 10 pawns for positions where it cannot demonstrate a win against itself. Perhaps for old nets produced before the temperature drop and TB re-scoring. And...

Re: Knight equals 48 pawns?

Well, sounds like you better work on Komodo TB scores... ;).

This is similar to what one sees traditional engines with special endgame cases (TBs or known win...

Re: Lc0 on RX Vega 11 GPU?
