i think it's a pretty easy fold.
His AF is pretty low (small sample, but this is also supported by a ridiculous VPIP vs PFR).
I tend to give fish credit for playing their hands completely straightforwardly in spots like this: set of 6s, 57, maybe 68s, maybe weirdly played monsters (sets, QT, T7).
i'm curious though, it might be a leak of mine. let me know how it turned out?

When fish shoves and you call you are risking $16.80 to win $23.30. Pot odds are 1.4:1 (rounded up from 1.38:1), so you need to be right around 40% of the time to break even.

I run into a some 25NL Zoom fish that like shoving top pair with good kicker sometimes. Impossible to know if your fish is that sort of fish without reads though. I think fold is best if you don't know anything about the fish, that is a great flop for a player with a BB flatting hand chart (flush draws, small pocket pairs and suited or non-suited connectors) and so the fish shove could be legit.

All of that logic aside, my wild-stab-in-the-dark-guess with no logic whatsoever is that fish has J6o, because that's a super-fishy hand to play :)

With no reads that villain is aggro (in the very small sample you get the contrary) I think folding turn is best by far... there are just too many combos that has us beat (we also have Ad blocking one of the FDs).

Replaying the hand, although might look nitty and odd with such a strong hand like AA, but I would just check behind.. the board is very drawheavy you will almost never get 3streets of value anyway. So I would check behind flop, bet t+r

Pretty easy fold against this sizing. Vs a fish probably against all sizings.

Thanks for the replies. Lewis, he had J6o.

haha, nice river Jay! (and nice read by Student).
