And.. surprize - Gullydeckel does just piecetable eval, not even incremented (faster) way; and simple pawn eval. Compare this to Phalanx: lots of (slow) calls to check for pins, attacked squares near king; whole king safety, genarating checks in qsearch (Gully does not do them) and full-fledged eval. While both use same 0x88 representation (mine too, btw), it's apples to oranges... -Andrew-
