TC?
GPU Leela was using?
CPU and thread count for K8?

That's one out of three questions. It doesn't specify the GPU and it doesn't say what CPU was in use (I'm guessing one thread?).

Thx for the game anyway, it'll be good to have a different take on positions (other than the boring old engines).

Great game. Good karma.

position after 38 h4 is instructive, centre fortress for white, what can black do other than shiffle around his b2 rook? Positional win, tactics not needed, although they will magically come for Leela as a consequence of the positional dominance. This theme, unbalanced RNP endings, has become quite familiar, Leela has learnt the patterns that, statistically, lead to wins. No amount of "tactics" or lookahead can compensate. Leela removes Lefler's testicles. Karma. And best wishes to Vas Rajlich.
