Pawn Blockages

Chiron can instantly detect and correctly score as draw most of the positions with dynamic or static pawn blockages. Many engines, even the strongest ones, will score the following positions with incorrect high values (click on B8 to get the FEN).The code for detection has been developed following the rules described by Omid David in his paper “Blockage Detection in Pawn Endgames”. This feature doesn’t make Chiron stronger but it could be interesting for analysis and could avoid Chiron to enter a draw endgame thinking it could be won.
