  • 977ca40d6d Supply the "upperbound" and "lowerbound" parameters in UCI search output when the score is outside the root window. Tord Romstad 2009-08-07 16:26:24 +02:00
  • ae49677446 Fixed a bug in PV extraction from the transposition table: The previous used move_is_legal to verify that the move from the TT was legal, and the old version of move_is_legal only works when the side to move is not in check. Fixed this by adding a separate, slower version of move_is_legal which works even when the side to move is in check. Tord Romstad 2009-08-06 18:07:32 +02:00
  • 2fff532f4e Moved the code for extracting the PV from the TT to tt.cpp, where it belongs. Tord Romstad 2009-08-06 14:02:53 +02:00

  • 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).
