I agree it was interesting. At first glance it looked harder than it really was.
MrOojer -- my inference chain wasn't short, but I think that's because I went counter-clockwise looking for eliminations: if I'd gone clockwise from my start point (ymmv) I might have found the conflict sooner.
just one 50:50 guess
I must have made a mistake (in my favor). The whole thing solved like an easy -- no greens, no guesses/inferences, no special techniques.
