As far as I know crafty don´t do "bad SEE" moves in quiescense, but has no futility, ext. futility or razoring. 2. extension issues. Crafty only increment many extensions by 3/4 ply (skipping every 3-rd move extension out of four). 3. eval-issues!! In my engine I have got a big node reduction because of changing eval.
