Chess engine: Stockfish 19091210

Stockfish - UCI chess engine
Interesting compiled by Vizvezdenec

This patch greatly scales down complexity of endgames when the 
following conditions are all true together: 

- pawns are all on one flank 
- stronger side king is not outflanking weaker side 
- no passed pawns are present 

This should improve stockfish evaluation of obvious draws 4 vs 3, 3 vs 2 and 2 vs 1 pawns in rook/queen/knight/bishop single flank endgames where strong side can not make progress.
