Allow for higher depths. (#2147) High rootDepths, selDepths and generally searches are increasingly common with long time control games, analysis, and improving hardware. In this case, depths of MAX_DEPTH/MAX_PLY (128) can be reached, and the search tree is truncated. In principle MAX_PLY can be easily increased, except for a technicality of storing depths in a signed 8 bit int in the TT. This patch increases MAX_PLY by storing the depth in an unsigned 8 bit, after shifting by the most negative depth stored in TT (DEPTH_NONE). No regression at STC: LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 42235 W: 9565 L: 9484 D: 23186 http://tests.stockfishchess.org/tests/view/5cdb35360ebc5925cf0595e1 Verified to reach high depths on k1b5/1p1p4/pP1Pp3/K2pPp2/1P1p1P2/3P1P2/5P2/8 w - - info depth 142 seldepth 154 multipv 1 score cp 537 nodes 26740713110 ...
