[Closed] 100 NL - AK 4bet pot IP - call river?

I would bet bigger on the turn. The turn card is pretty good for you, since he's now gonna peel you with sutff like TT or JJ with :club:. And you gotta protect, s I bet something like $36. It's not like you're gonna be folding this anyway. I mean, you have TP/TK in a 4b pot for 100bb vs an apparent fish.

And on the river I would definitely lok him up. I don't expect him to be calling a 4b OOP with many Q's, even though he's a fish, I don't think you'll often see KQ or QJ. The only possible Q is AQ, but he's often getting aggressive with it on the turn and then there's only 4 combos of AQ left in the deck. And since he's a fish, he will be doing unreasonable stuff like you said, so I wouldn't fold it.

As caltabiano said: once he calls the 4bet OOP he should never have AQ and KQ (he doesn't look fishy to me, just a bit too loose with his coldcalling preflop - but if it's calling IP it might even be good for the most part).

In fact there are no hands with which he could reasonably call a 4bet OOP, but imo he's more likely to call pairs than other stuff, and if he calls Ax there are few combinations of it in his range that beat you (the 4 AQ).

So i'd call this, too.
