Any reads on villain?

I usually fold this pre-flop, but since you called, the flop bet seems OK. Checking behind on the turn is kind of passive, but I probably do the same. You could argue betting to make villain pay for chasing his draw.

As for the river, the overbet is kind of weird... it's really hard to tell what's going on here without a read. Sometimes people will do this as a steal, but other times it'll be with the nuts.

I might just call the river, but if you're going to raise, make it a bit more so you get some value out of the villain while still giving him odds. The only thing you're beating here is trip 7s with a weaker kicker, so the fold to the AI raise seems fine.

It's really hard to put villain on a hand here, especially given his crazy river line. Given the type of hands he's rep'ing, his line doesn't really make sense. He should've raised a set or two-pair on the flop and bet turn if he turned a set with 22. But even if villain played this horribly, I don't see him taking this river line with a hand you beat.
