Typical 2/3/5 with UTG straddle. Table has two 400+BB stacks and playing quite loose overall. I sat couple of hours ago, running hot, got paid off with KK twice, have about $1500. Villian just joined the tabled, maybe played a few hands.

On to the hand. Effective stacks - about $800 (160BB)

PF: folds to MP1, who raises to $30 (standard raise on the table, when straddle is playing), MP2 (villian) calls. Folds to me in SB, I look at T T raise it up $95, MP1 calls, MP2 calls.

Flop: 9 2 K
I bet $125, MP1 folds, MP2 calls

Turn: Q
I check, MP2 goes all-in for about $500 (100BB)

What's my play here? I would like to hear thoughts on my bet-sizing. In retrospect, I should have raised higher pre. Flop bet is small for the pot size, but I am liking these smaller 1/3 - 1/2 pot bets as they give me good balance and people fold a lot on K high flops in 3-bet pots, unless they have a K, even if my bet size is small relative to the pot.

Reads on the villian: he put in a bet of $75 to call my bet and dealer corrected him to $95 and he hesitated a little bit. I felt like he had a small pair or suited cards here. This is pretty weak tell as I haven't seen him enough.

I think your frist mistake was a bit small reraise preflop , i would choise size of lets say around 120-135$, on flop i would probly with 10/10 decie to go check in 2 people , but if i know people their style etc and i bet the flop , then ill bet the trun also and see what happens.
But also think about sizing.

pre is too small and makes flop harder to play. multi-way idk how many of these middling pocket pairs we want to bet. definitely check folding turn

What's the range you are assigning to MP2 that makes us check/fold here on turn?

I'd typically flat pre here against an unknown because I don't really want to make a big pot from OOP when I'm going to be a bit lost not knowing how the opponent plays postflop. Threebetting isn't wrong, obviously, but I don't think it loses much EV here to take the cautious route. TT has a different profile in terms of what you end up with postflop than something like AK.

As played, if V had a flush draw he probably just shoves flop, and flush draws is most of what we beat here. It's hard to come up with too many other hands that can call pre, flat flop and aren't beating us. In terms of what he could have that does beat us, there's KQ, any of the sets, and KTs or KJs if this guy is on the looser side.

You're offering close to 3 to 1 pre, so you are pretty much guaranteeing you will see a 3 way pot out of position with a medium strength hand.

Considering the structure of the game 30 is on the small side for a preflop raise, so I would just call with your great pot odds. If you do decide to 3bet then you need to make it larger, that often results in turning a hand like 10s into a pure bluff though, whereas in a regular structure game your 3bet is for value. It's not an easy decision, but I usually go with calling if the the other players make a lot of post flop mistakes.

TT is very good against loose ranges but it's not that strong against a raising range, e.g. it's a 46% underdog against { TT+,AJs+,KQs,AJo+,KQo } which frankly is looser than quite a lot of LLSNL players raise. I get the basic plan which is "threebet pre, pick up the dead money, take it down a lot and rely on TT's equity as backup" but that last bit is imo kind of suspect when OOP in a large pot. The times you get to check the hand down and win are the times when your opponent flopped nothing anyway and you could just take it down betting if you had instead bluff threebet with a suited ace or something, where you have a blocker and aren't essentially turning a good hand into a bluff.

Taking a flop instead has advantages, flopping a set will be a pretty sweet spot and you can use it unimproved as a bluffcatcher.

First of all, your stack is not 160BBs it's 80BBs. It's not even really as deep as 80BBs since there's more dead money in the pot than there would be in a 5/10 game (an extra $5).

Your preflop sizing is criminally small out of position. You need to be making it at least $130 here, and probably $140.

As played preflop, just check/fold the flop. You're gonna have a really bad time trying to realize your equity on that board OOP against two players.

As played flop, I think you should be open-jamming the turn with the straight blockers. Try and get opponent to fold a king.

After checking, fold to his shove.

Raise bigger pre. 1/2 pot or less flop.

Check fold turn.
