Just wondering if you're planning on implementing ponder? I run all my tournaments with 1 thread + ponder, and it really helps at short time controls like 1m + 1s or 2m + 1s.
I noticed that ChessBrainVB and for example Halogen lose quite some performance when going from 1m + 1s to 2m + 1s, compared to the pondering engines. It's like it doesn't have a huge effect at 1m, but at 2m is like some sort of sweet spot and it helps a lot.
