@snicolet If merged today, you might want to send this version to TCEC for Cup9, as the one planned for playing is a few patches old. Submission ends today 23:59h UTC.

It would be interesting to test if the other pruning/reduction heuristics
in master which are using the improving variable (ie the sign of improvement)
could benefit from a smooth function of the improvement value (or maybe a
Relu of the improvement value).
