I probably let him have it.

Villain's limp-reraise represents AA/KK, basically, although of course he won't always have one of those hands, and the fact that it's a min-LRR clouds the issue (is he trying to be trappy, or is he making a pot-building reraise with something speculative to be a nuisance or to try to take the initiative?).

I guess it's possible he has 44 and was trying to make sure he got it HU preflop versus your "probable" AK. But I don't like the looks of that flop bomb much, even though it does seem sort of inconsistent with Villain's preflop trickery.

Also, our sketchy stats read on Villain does suggest he's not a nutcase.

And, having said all of that, I do still think the decision is close.
