A fascinating position. I see 1.Rxf5 exf5 2.Qxh6+ Kxh6 3.Rh1+ Kg6 4.Kf4 ("and
wins") almost instantly, in 10 seconds or so. Probably most fairly strong human
players would do the same. My guess was that engines would do much better. But
no, you're right: many of them have a bit of trouble:

So Nimzo gets it instantly, and Doctor?, BamBam -two very weak engines- perform
much better than some of the top ones. Fritz, Shredder, Chess Tiger 14 don't
impress to say the least. In this kind of position, List and Ruffian clearly do
better.
Nimzo has been the only engine capable to beat me in matter of speed.
