Probably it is mate 15 plys deep. The position above is 8 moves deep and here my time (like I said before) is not that brilliant. Selective in 8 moves find mate after 63 seconds. Celeron 600, No hash. Position probably is not very easy even if it look to be so. All pieces are together and this is why one could expect very easy win. My branching was not very good and my program went only 7 moves deep. Seven moves took already two hours to say that no mate in seven exist. Cheers, Leonid.
