That would convert many wins into draws. Stalemate is quite rare in practical play between chess masters and can be disregarded. >7.5 gigs is a trivial amount of disk space today, with new machines usually >coming with at least a 60 gig drive. Well, my hard drive is 12GB, so the size of the TBs is a factor for me. Via simplifying assumptions based on the relative rarity of certain situations in practical play, I think the endgame tablebases could be reduced to no more than 1GB and still contain most of the strength which they presently offer to a chess program. In other words rather than an elegant and complete endgame solution, an incomplete (but sufficient) set of tables is probably do-able. But I don't know how to code it. WP
