No Leonid, we did not forget you ;-) > >Ok, finally there is some result. After 38.3 hours Chest on a K7/600 with >350MB hash finds two key moves for a mate in 12: Great, Heiner! I don't have that many positions in 12 moves. I already indicated on mine (I keep for me each position printed in graphics) exact minimal number of moves that lead to mate. This position not only can be used in the nearest future when I will change something in my program, and will need some verification, it is position for the future. Some positions from the past are now unseless. Reason for this is that old one became simply too short, like positions in five moves. You can't see with them no more any speeding, since the time is very often neat zero. Thanks, Heiner!
