I am  a little bit intrigated about "10 ply selective search". What it mean? 10
plys inside of total 16 plys were searched as selective and other 6  by brute
force? Or, maybe, maximum responsed that are looked during the selective
searched could be 10, from maybe average 50 legal moves inside of each ply. Will
appreciate your response, if you know what the program say with this expression.

Cheers,
Leonid.
