I think your program has to have endgame knowledge built into it because it would be imposible (these days) to cover every position in the tablebases. Then there's a matter of being practical too, in order to have the 3 & 4 man tablebases in their compressed form, you only need about 30mb of spare space to store them, but I'm hearing that that figure goes up to about 6Gb if you want to have all the 5pc tablebases in compressed form. Allot of us can't spare that much harddrive space. Pete
