I checked this. Time/solution is the same in the positions I tried. F6 light played 2 blitz 5 games against H732 in the interface of F532, one of 107 moves, so no move limitations. By the way, F6 light won both games. It uses the Nalimov tablebases. The only difference I noticed is the 32MB limit for hashtables. Database and GUI options seem to be identical to the commercial F6. The ways of marketing are unfathomable... Enrique >--- >Shep
