I couldn't solve it either... :scratch: In fact, Herr Fritz VIII thinks it's really a mate in 4...

Hiarcs couldn't find it either- it found the same lines as Fritz. I think these types of engines stop analyzing as soon as they find a mate. I'm guessing since Hiarcs looked at the logical Ng6+ first (rather than the slightly odd key move) and found a mate, there was no need (to its limited silicon brain) to analyze further. Of course when the keymove was played for it, it instantly found the remainder of the correct solution.

Hi DeepBlue,

richardfry found the solution in the third post from the top. I've cleaned it up a little and reposted it below since it's really cool and worth preserving. Click on the "Show it" link below. People use that feature to avoid accidentally showing "spoilers" openly in this sort of thread.

Post Re: tricky checkmate in 3
lets see if all the chess tempo work pays off. my notation skills are lacking but no computer used.


1. Ng6+ forces pawn to take back
2. Qg4
3. Q to h file checkmate?
