We're about dead even vs KK+ and AK on the flop. But if you add AQ in his range we're a 3:1 fav, but AQ is kinda meh. He may expect you to have AQ in this spot though (with him having AK) because he's not soul reading your set of 3s by a standard cbet. Ugh, this is actually a pretty sick spot now that I think about it. Still don't think I can find a fold tho.
