DoubleCheck 2.4 released
change log:
- search: rewrote the PVS + reduction bit a little. Thanks to Marco Costalba for his advice on this.
- MAX_GAME_PLY now equals 0x400, so games can safely last 0x400-0x80 half-moves before the game stack.
writes out of its allocated memory and crashes everything.
- qsearch: do not write in the TT when the move loop was empty.
- eval: mobility rewritten, should make a bit more sense now.
- search: introduced double reductions for late quiet moves.
- search: do not reduce castling moves.
- search: eval pruning rather than reduce.
