In Eubos these are referred to as 'Counted Attack Masks' Add evaluation for pawn storm and pawn shields into the king safety algorithm Designed and implemented a new method of efficiently finding positions where there is a passed pawn present, used as a parameter in attack mask computation Tuning / Optimisation / Tweaks Revise King Safety evaluation into 3 parts; 1) exposure, 2) vulnerability and 3) mate threat Counted attac...
