Hi, Paul,

If you do something interesting, and it is not "state secret", say me later what
you do. Curious to see what other people do in their free time.

It could be that you will find mate just after 12 moves. Mine found mate in 12
(13 sec) and all mate parameters are very acceptable. In this position checking
moves lead to mate.

I searched this mate only 10 moves by brute force. Eleven must take around 3
hours and this I will be able to do only at night. After 10, will know for sure
how deep this position really is.

Heiner's solver with hash could respond more quickly but for now I try to use
only my program. It could be that at certain point I will hit some bug. Solving
mate is all the time good fun but also very useful verification.
