Please mention your game and your hardware. Chest 3.19 (PIII/550 500MB hash) needs 731 seconds to show that there is no mate in 16. Note that chest 3.19 does not access any endgame tables. There is some direct EG table access on the net. I tried http://chess.liveonthenet.com/chess/endings/ and it says: mate in 26 by Kf4. Since that site states to use the Thompson's CDs (which are shortest conversion if recall correctly), I'm not sure whether this is shortest mate. Also, this was just an example position by José de Jesús García Ruvalcaba, and most probably not the one, the original poster (pavel) wanted to talk about. Heiner >Thanks, >Leonid.
