Villain's play is definitely spazzalicious. Do you have any history with him? Is he frustration spazzing from being raised all the time, that kind of thing? If so, I don't hate a call. But without history, I think it's a fold. I would expect villain to often have a bizarro two pair here.

Oh you say he's an unknown. Vs an unknown I'd definitely fold here. I would need a pretty good read to call an overbet all-in with one pair.

Yeah well, he's sitting short and the donkcall is, as you say, spaztastic.

While I do expect to see a bizarre 2 pair here sometimes, I don't get wtf he can donkcall the flop with that then shoves the turn.

I mean, when I raise the flop, if he has a value hand, he's surely either gonna:

a. 3bet the flop

or

b. Flat the flop raise then check the turn to me and extract the monies

The line he takes just seems to shout "FOLD" to me, so I expect more spaz than value hands here.

What was his timing?

My feel is this is bs, and I'm calling here.

I agree that the whole impression is 'Go away' but I'm still concerned about his flop call. That's the one part that doesn't say air.

Yeah I think we should call. Sets will rarely donk pot on the flop. You'll see 88 99 here that have the old fish thought proces of "oh no my hand got worse time to jam" same one they use when they 3 bet KK and shove Axx flops for 4x pot. This plus our equity vs better hands makes me station for sure.

Think calling flop is almost certainly better than raising btw.

This is probably some 3xss, 5xss, 4xss type hand, or some weirdly played 66,77,88,5x.
