Laggy player opens in the HJ, I 3 bet from the CO and only he calls.

A72r....Lets say I have KQ or QJs or something like that. He checks, I bet and he calls. I usually check the turn and they bet the river and I fold. I'm wondering if I'm getting floated here more than I think. Should I be firing most turns? Or is this just a situation where I missed and time to move on? I think I may underestimate how often people will peel lightly even in 3 bet situations.

How about on this board?

What about?

If you “usually” check the turn and fold to a river bet, then if your opponents are observant at all, they *should* be betting the river with any two cards...

You don’t need to spew chips, but you do need to bet again on the turn and/or call the river bet in this situation often enough that your holding isn’t totally transparent!

I mean it’s fine to have a split range of give ups and continues depending upon the turn. I would be firing turns that give me equity and value betting turns that give me pairs. We’re going to be making pairs on the turn or river 1/4 times.

For someone to be peeling light planning on check/folding the turn unimproved and then betting any river after the turn checks though, on a dry ace high board, is pretty ambitious and I wouldn't worry too much about it. They need to hit the parlay of you (a) not having a showdownable hand on the flop; (b) not having a hand you can keep betting on the turn; and (c) not picking up anything that allows you to get to shown on the turn or river.

Also, I assume you are checking back some showdownable hands on the turn to induce river bluffs and snapping those off. If you are betting the turn with everything that could call a river bet had you instead checked, I think you are betting the turn too much and decapitating your turn checkback range.

Putting yourself in villain's shoes, against a player with such a decapitated checkback range, you might be able to profitably peel flops OOP with the intention of taking the pot away on the river, but I think you would want to be doing that on boards and with hands that also give you a decent opportunity to also improve. I am not going to be doing that against a player with a balanced turn checkback range, and I am not going to do it on ace high boards with trash.

Side note -- depending on the board texture, KQ might be a call after checking the turn as a bluffcatcher.

I think it is pretty uncommon for even LAGgy players to pure float you on the flop in order to bluff you on the river. They are much more likely to just check-raise you with weak backdoors on the flop. Or if they think you are weak-tight, they may start check-raising pure air on the flop. If you suspect you are being floated, I would just start calling rivers lighter or even bluff raising air on the river after checking the turn. I think both of these options will be more effective than barreling trash on the turn. For example, you can call KQ on the river to pick off bluffs. And you can raise QJ when the turn bricks and a T comes on the river. If they think you are weak-tight, they will likely just assume you are spiking sets on the river.
