Eman 4.50 is ready and good to go
In this release, I have added the following:
Disable MoveCount pruning for PV Nodes
Added Live Book Depth option to limit number of moves retrieved from the Live Book. Default = 100, Minimum = 1, Maximum = 100
Added learn=1 to Live Book API probe code which allows automatic learning functionality in the Live Book (Check: https://www.chessdb.cn/cloudbookc_api_en.html). Special thanks to Hans Pieters for raising this point.
Some serious soul-searching in previous logic which contradicts with latest SF updates (after 4.41 was released). Those SF updates modify the logic in areas that I have already modified in Eman, the combined modifications made Eman very weak. I took considerable amount of time to finally find the perfect combination of both changes.
This version also includes all updates from Stockfish development branch to this date (Total 12 updates since Eman 4.41 was released)
