Pretty good position, lots of programs have trouble with this. Amateur takes 5 min on an old athlon, though the fully correct pv takes awhile longer.

Very interesting position indeed. It is not so simple because there are many intermediate moves. Gaviota struggles with it and finds it in 39 minutes (2351.2 seconds) in an AMD 2.4 Ghz.

Yes, I tried a couple of programs lower down the ratings. AICE had not found it after 20 mins, and Clueless V1.4 had not found it after 30 mins (Q6600). Both were at Bd2.
