Could someone help or say 'it's >nonsense to cache see'? #2 seems interesting, but to get the info necessary for lookup you would have to know every piece/capture order involved in the capture -- That's already expensive. Calculating the SEE score from the predicted series of captures costs near 0. Also keep in mind that most captures sequences involve 1-2 captures, so it's not slow compared to other methods. Michael
