Hi all, This is my first post to this forum [I have been reading it for some time] Some questions in arbitrary order: 1. should PVS kick in after 1st move, or after PV found as Bruce suggests on his page? [I *think* tree is smaller Bruce's way] 2. if using fail soft, which is right: pvs(-best-1, best) or pvs(-alpha-1, alpha) ? 3. depending on 2., how do you test for failure, and what bounds to use for research? best or alpha 4. Fruit uses 'mate distance prunning' - I read in the archive [now down], where some suggest using shallower mate score hash entries, and others suggest boosting the 'draft' of mate scores [which is similar, I suppose] Are these all different versions of the same thing? - any help? Thanks for *ALL* your help: past, present, and future; David
