On WAC #38: 4k3/p4prp/1p6/2b5/8/2Q3P1/P2R1PKP/4q3 w - - bm Rd8+; id WAC038; My program favors the 'best move' for 9 plies, and then switches to Qd3 with a pv that wins the Q for the R exactly the same, just with a small positional difference. Is my program correct? Will Qd3 also win? Crafty gives similar scores for both moves. James Position #38 Best move(s): Rd8+ Unsolved.
