Fix check for bishop pair in material imbalance Prefer pos.bishop_pair() to pos.count<BISHOP>(WHITE) > 1 because the first checks that the two bishops are on different color squares. Although the change seems to kick in only in very rare cases, quite surprisingly it was able to pass SPRT test at short TC. LLR: 2.95 (-2.94,2.94) Total: 39818 W: 8174 L: 7956 D: 23688 bench: 3453941
