LOL, you must be joking. I think with this kind of position you'll beat most of
the ones that just beat Yace in the 1. g4 one.
I can't see how this could be solved fast without specific knowledge. It is
amazing how fast you get the fail low on Ke3.
Of the ones I tried the only program I found that was faster than Yace was
Shredder 6. A _very_ nice position as it is easy to understand - it would fit
well into the PET testsuite.
