0d69ac33ff Remove even more redundancy in endgame functions handling Marco Costalba 2009-07-17 14:32:27 +02:00
342c8c883c Removed an incorrect assert() statement in search.cpp, which asserted that a static eval cached in the transposition table would always equal the static eval of the current position. This is in general not true, because the cached value could be from a previous search with different evaluation parameter settings, or from a search from the opposite side (Stockfish's evaluation function is assymmetric by default).
