Really interesting flop spot

[shipitgood]

Sent from I phone if I miss anything out let me know. We have ak Os in the bb. Utg + 1 opens, cut off 3 bets, we 4 bet original raiser folds and co calls. Both players are quite tight. Flop comes down k34 rainbow. We bet 35% pot, and he makes a 1.5 x raise. Its really interesting, don't see any merit in raising. So feel its a call or a fold. Although he's tight he will have moves, but don't ever see this as being a bluff or kq. What would you do here on the flop. I'm really surprised he's raised the flop here, I would not have a flop raising range here on this board\ spot. IMO his range is aa kk ak, and raising any of these hands seems utterly bizarre. Like if he has kk he has the board locked up, if he has aces I'm going to have kings here sometimes, if it's ak what worse hand does he expect to call. All that being said I can't see this being s bluff, like all of a sudden he's turning queens or jacks into a bluff, fascinating hand

How much was the 3 or 4 bet pre flop?

I thinking folding is too weak and calling is fine here. Agree there is no point in raising again on the flop.

4 bet was like 2.3-2.5 x, this was such an interesting spot. What does everyone think villains range is here. Could this be a <1% Bluff? It just doesn't seem like this can be a bluff. Thinking about it he never has kk here I shouldn't imagine. If he has ak he could possibly do this, but can't really see that. Would seem the most likely hand he holds is aa.

He could might have here,but if he did he will probably 5bet often. Same with kk. He could of made a mistake and called with kq suited (stubborn maybe?).or perhaps with a small pair which flopped a set.

It is a dry board so he could be making a move thinking you have aq or pocket 10's or something you might fold this flop, or at least you will fold then turn if he continues then aggression.

Think I would just be check calling this one down and noting the player if he did turns up with an unusual hand.

In this exact spot, I don't think he has a 5 betting range against me.

Did you fold? Did you get to see his hand?
