Thanks, great test position. Stockfish 1.7.1 takes 13:42 to find Kd6 ...lech wrote:[d] 8/p2K4/P5B1/8/3n4/2k2p2/2P2P2/8 w - -

It seems to be very hard to do it.Edmund wrote:Then the knight defends the square from d4 with the king guarding the knight.
It is realy a valuable position. Stockfish has a trouble since doesnt use EGTB. I recommend to use Houdini. Houdini has a code to play KQ vs KP with relative pawn a7 (c7,f7,h7).David Dahlem wrote:Thanks, great test position.

Given more time, i think Stockfish would find a forced mate in this position, without tablebases.lech wrote:Houdini has another problem and probably can't solve it.
Maybe Stockfish is realy the best in endgames.![]()
It would be fine to test this position with 8-cpu by many engines.
Using 4 cores Houdini 1.02 finds Kd6 at depth 31 in about 2 minutes:lech wrote:Houdini has another problem and probably can't solve it.
