First challenge : your engine should avoid the ridiculous 1.Kc5 fast ( hard for some) b.) Then many are stuck with 1.Ke4 b4 2.h6 a5 and think this is a draw ( black simply plays Kf5 and e5 then). If your engine manages to find this fast - give it a little more time and see it missing the solution again. Of all the programs I tried only Fritz managed to solve this in a reasonable time. I don't know if this position is already part of some testsuite. Cheers, pete
