I have been implementing SEE in the quiescent search, which slow the nodes per second down but decreases the time taken to reach a fixed depth and so is a win overall. The SEE discards from further consideration (in the quiescent search) those captures which apparently loose material, by working through the sequence of captures on the target square. All standard stuff – I think. One of the problems with this approach is that a capture sequence focussed on a particular target square may appear to win material but, in fact, does not because one of the capturing pieces is pinned against a piece of higher value and so cannot move. Do other just use SEE to order the sequence of moves or throw them out as futile – as Crafty does if I understand the code. Using SEE to only order moves largely negates its advantage. Frank.
