I'd ask if you're a GM yet but I know these tournaments take like 4 years :) Re. white giving up the h-pawn - as soon as this happens, you can already access the tablebases. For instance, the variation 1. .. Nc4 2. Kf2 Kh4 3. Bg8 Nd6 4. Ke3 Kh3 5. Kf4 Kxh2 6. Ke5 Nc8 is drawn. Maybe you can enumerate all the different ways in which white can give up the h-pawn, and look up each possibility in the TBs. As far as generating the six-piece tablebase - you might try contacting Eugene Nalimov (obviously) or maybe Bob Hyatt. Vas
