I lost my stack on this hand and I'm trying to figure out if I played it wrong or if it was just a cooler.

I was on a fairly soft 1-2 table, 9 seated, with a few hyper-aggressive players, prone to betting or calling with anything, 1 or 2 nits, a couple of noobs, and one TAG. My chip stack was $160.

I limped for $2 preflop in the cutoff with 10-9 offsuit into a 7 way pot. The button folded, so I was last to act when the flop came 9D, 6S, 2D. Everyone checked to me and I bet $20 into a $14 pot. I'd made the same move twice before and everyone had folded to me. One of the noobs went all in for $11, the TAG called UTG, and one of the nits sitting to my right called.

The turn was a 5C, and I bet $45. TAG folded and nit called.

River was a 9S. Nit checked, I shoved, and he called, showing 9D, QS.

Did I mis-play the hand? Is there any way I could have gotten away from this?

Are there two 9 in the deck?

I am not sure he is really a "nit" if he limped middle position with Q9o...

When the "nit" called your turn bet of $45, what range did you put him on?

Only one 9D in the deck. He had Q-9 os. When he called the $45 on the turn I put him on a likely overpair, or possibly 88 or 77. He didn't seem to be the type to call that sized bet on a flush draw.

I was prepared to check the river unless another 9 or a 10 hit the board.

Don't post results.

I check the turn. Top pair no kicker isn't a hand I get aggro with.

Agree with comment about thinking about what your opponents have. You easily could have been crushed on the turn as a straight came in. 78 is definitely in 1/2 players pf limp range - even a Nit in MP.

You overplayed your hand ott. Otf your play is questionable if you dont know why your making it. Ott why are you betting, straight got there and building a side pot vs a nit and a tag with a 9, 10 kicker is horrible planning. Otr you have a bluff catcher vs the nit. Every time you get to the river review the hand before acting. You will see that you beat no hands in his value range.

Do you think a nit is going to call $45 on the turn with middle pair and a gut shot?

I feel you should pay attention a little closer to the players before you label them.

FWIW I think that a nit would call $45 with overs and a flush draw a lot more often than with middle pair and a gut shot.

On the river I don't like a shove. What hand that is less than three 9's with a 10 kicker is going to call? Checking does seem bad also. I might make a smallish bet if I feel the V is going to call me down lightly.

I think betting the turn for value is pretty optimistic given the players.

Vs your average loose passive calling station , sure hand was WP (though turn is prob still fairly thin just not so much so , and bad players don't fold draws or a hand like 77-88 there) , but vs a "nit" and a "tag" i think we can go ahead and slow down on the turn.

river is unfortunate because of how well it improves our "absolute" hand strength , but relative to ranges I don't think our hand is all THAT strong anymore. I have no idea how i play this river "as played"

than again i think your reads are fairly off (do most nits c/call 2 streets with TPGK in a 7way pot?)

I don't mind the turn bet as much as I mind the river bet.

You made a fairly common mistake for live low stakes players: you assumed that when you made trips on the river, that it improved your hand significantly, because you went from having a pair to having trips. But it did not actually change your hand's strength relative to almost any likely holdings.

In a limped pot, the only hand you could argue that one of them has that you moved ahead of is TT. That's it.

You beat TT, 88, 77, 98 and 97, and you lose to 96, J9, Q9, K9, A9, 78, 55, 66 and 22. To reiterate, your hand strength relative to these hands did not change when you made trips on the river.

There's a lot of pair and a draw type stuff in the hands that we are ahead of, not to mention people who might call with a flush draw, so I don't mind a bet on the turn. But we can't assume that 88 and 77 will call a 3rd bet on the river, and even TT will often find a fold, so a third barrel on the river is way thinner than betting the turn, despite the fact that our hand rank improved.

MPethy nailed it. It looks like a 9 helped you, but really did little to change who was ahead and behind. When you shove the river, rarely will you be called by a worse hand in this spot IMO
