€2/€5 — AA: Check of whole line, but especialy turn

Seems fine. Hard to evaluate how European players play. 3! size is dependent on villain and table. Obviously, normally standard sizing. This is a board that strongly favors your range, so generally don't like checking in position to induce. Would not expect villain to bluff much on this board. Board is very dry, but don't want to give backdoor flush draw a free card. Obviously a great board for JJ+/AK, so hard to get action.

You're playing 70BB deep so a lot of this is overthink. That being said:

This shallow you need to decide before your flop bet whether you are playing a two street game or three street. You got tangled up with your sizing.

What sort of range do you put CO on after calling your half pot sized bet on a Kxx rainbow flop in a 3bet pot?

What would you do on the turn with nothing?

If you are considering checking back turn, what is your aim? (Which comes back to what sort of hands call your flop bet) To be more explicit: what sort of bluff hands does he have?

OP, even on line check threads, please don't include results until at least 24 hours after posting the hand. Here, it's not really a line check thread, as you have multiple questions about turn, so I edited out your turn action as well.

I agree with Moxterite: bet 30 or 75 on the flop. 75 gives an easy shove on the turn. 30 lets you bet all three streets.

AP, I’m betting the turn small to 60 and looking to get it in on the river. I like to bet my good hands against weak players who call too wide.

Just tank shove the turn - this isn't a turn you want to check back as most of his holdings are value hands and he has a lot of Kx that you can stack off.

PRE - seems standard. I might size up a bit if I think V is going to continue too wide. I might size down a bit when we're starting out somewhat shallow.

FLOP - half pot would usually seem too big for a c-bet in a 3BP, but I don't hate it if we're trying to set up a turn jam.

It's hard for us to be balanced at this stack depth. V probably won't float too wide from OOP.

TURN - I think I'd just jam on this card, with the Ah in our hand, and hope he has KX.

V opened for a raise, called our 3B, and x/c'd a 1/2 pot c-bet on a fairly dry, K-high board. If he floated wide, he's probably not going to call another bet, of any size. We know he didn't pick up the NFD, but we may have. So I just want to target his TP combos by jamming.

Alternatively, we could barrel for a small size, like 40% pot, and hope he raises.

If the Kh was on board, and I thought he was capable, I might be tempted to check back, hoping to induce a river bluff. But in order to do that, we have to think he'll over-fold to a turn barrel, but also over-bluff river when we check back turn. We also need to hope the river isn't another heart.

I'd really prefer to just bet our hand for value on the turn, targeting KX.

Pre is fine.

The highlighted. This is really not a hand to spend a lot of time thinking about. You have 70bb with an overpair on a K high board.

No, people don't bluff rivers enough regardless of what stake, we should do the betting ourselves with this hand though.

Spr of 3, we have AA on Kxx in a 3! pot. Just b/b/jam and don’t get lost in the weeds with fps ideas of checking back turn.

Like the way you played it. I would bet small on the turn which might induce a raise, but it’s fine if he calls. This is better than a check & giving away a FreeCard.

Not sure Ah matters more than reducing villains chance of having hearts - if villain hits the flush, you won’t make him fold.

The main thing is how happy villain is with his hand, because getting the money in at any point is fine if you think he will call.

I can absolutely promise you that I am a tighter player than you. The thoughts go round that they will fold, but they usually don’t. Almost never should you check a strong hand - once you get nothing from that street, their range narrows & they fold the next street often.

Check flop, bet turn is an underbluffed line
Check turn, bet river and you’re only getting called by better hands.

Mostly forget image with big hands and bet them. I am often positive everyone will fold, hadn’t played any hands in hours, but I 4Bet my AA pre-flop and get two callers. Don’t leave money on the table.

Yeah this. Bet something on the turn, the rest on river.
