Calling river?

[cyg]

So I'm not sure if my call on the river was correct.
Villian is pretty strange, he is 4.4/2.2/1.0 on 45 hands.

What do you think? About the whole hand, not only the river. I was quite unsure of how to play it.

I dump this preflop UTG sometimes, as played, I play it the same. I don't know what a 4.4/2.2 plays here, if he has a set I probably pay him off for the 1/2 pot bet, it looks really weak, like maybe TT, 88 or something.

Villian was on a hand that I would have never put him.

[CaptUnlucky]

I play it the same, excluding preflop, but I'm too tight anyways.

i think u can let this go on the river. you represented the ace on the turn, and he says he can beat it on the river. looking back i really dont think its a bad call that you made, but im expecting to see something like A5 or A7 from villain on this river. theres really not too much u beat that hes representing.
