| !! latest version !!Author: Guenther Demetz Date: Tue Jan 28 16:28:56 2020 +0100 Timestamp: 1580225336 More bonus for bestMoves on past PV nodes It looks like it is important to keep past PV (ttPv) nodes as close as possible to current PV nodes. Credits to Mark Tenzer (31m059) & Stefan Geschwentner who first tried ideas on ttPv nodes.

The intention of the patch is to avoid aggressive null move pruning (NMP) in positions that have previously been found to be important (PV nodes). If we already do not apply NMP for current PV nodes, it makes sense to apply it less often for positions that have previously been PV nodes too.
