Re: AlphaZero No Castling Chess

Engines need to know that they're playing armageddon. So they need to be taught playing that mode. I agree, in the same way AlphaZero has been trained to play No Castling Chess, Lc0 must learn No Castling Chess or BNC with draw advantage, while alpha-beta programs must be also modified. A new openi...

Re: Elements of the ULTIMATE Chess GUI?

I think that one important thing for testing chess engines is the different time control for each side.

As far as I know only cutechess-cli and aquarium have this feature.

Is it so difficult to program this?

Re: 41800-boost-7000 net released

From your results it seems that the 1000 steps nets are better than the 7000 steps. From my results at longer time control the differences decrease..

About even with 41800, but plays more aggressively, less "trolly."

Re: 32930 Boost network available

After some additional testing, the boost net at 7000 steps is about the same head 2 head and vs sf10 at 1+1. The style of play is a bit different, however. Would appreciate feedback. https://github.com/dkappe/leela-chess-weights/wiki/Boost-Networks Thank you very much! I am going to test the new Bo...
