I only have a slow machine here (Mobile PIII-500) but even considering that it needs too much to find the solution: 37:28. Fortunately my current beta version (0.99.6b4) is a lot faster, although still not fast enough. It gives Qxc2 as the solution after 10:30, which is more or less on par with Ruffian (considering HW differences). At the moment my PC at home is playing some matches with a version that is tactically much stronger (but maybe positionally weaker, I don't know yet), so I will feed this position into that version too when I get home. Thanks for posting this position. Richard.
