Hi!

If you like, you can solve this mate:

[D]krqn4/rqP3qq/n1QQ4/bbNNBBqq/q1QQ4/Q1P3qq/RQ6/KRN5 w - -

I found very intriguing few anomalies about this position. NPS (node/per/second)
rate was very high while braching factor was unusually bad. This is true for
brute force search. NPS was 912k (8 plys search) when it could be expected as
low as 45k. When I went to try this position on Rebel 10, I found that Rebel's
NPS is, for the first time, lower that mine. Genius 4 time, for 8 plys search,
was almost the same as mine. Only from 10 plys my program started gaining some
modest distance. I never could see nothing like this before while verifying my
"normal" positions.

Please indicate your result,

Thanks,
Leonid.
