It wouldn't be *too* difficult to code for exactly this type of position. Kings and blocked pawns = draw if there are no entry squares for either King. But then you'd expect to see a draw at 0 ply, not 47. The 47 ply is just how long Fritz searched---the heuristic eval just gives 0 in this case (as does KnightCap's) and as do a bunch of other programs I bet. Jon
