I switched from Limit to NL .10/.20 about three months ago.
Here is what happened last night:
I'm holding Q6 offsuit in BB. I'm up against UTG and MP after the flop.
Flop comes Q27 (Can't remember, but all three cards were different suits).
MP bets .20, I and UTG call.
Turn is Q (Now I'm thinking how can I milk this for more.)
I check, UTG bets $1, MP folds, I raise to $2.
UTG raises to $6 so I go all in and he calls me.
UTG has Q2 and wins $28.

Anyone else run into this? I was expecting him to have 22 or 77, but not Q2.
This is the first time I've lost with 3 of a kind.

First time you've lost with three of a kind? Keep playing and you'll lose some more with three of a kind. Hands like this just happen and you're bound to lose some money.

If it makes you feel better, UTG is an idiot for playing Q2.

betting the flop harder, woulda made it an easier laydown

there's nothing you can do about that really except for playing it a little slower with such a low kicker. A reraise on top of your reraise is likely to mean he has a queen especially when he bet a little on the flop then the bet suddenly went massive on the turn. Mayb a larger reraise on your part to say $4 instead would have meant that you'd know if he reraised you on such a strong bet probably meant he had a boat or a higher kicker at least or mayb even a set.

Someone isn't going to bluff or bet with a pair of 7s that much when there are 2 queens down and the only other thing you can put him on is a set (which wld give him a full house) or a Q with most likely a higher kicker and therefore you're beat. I probably would have folded that seeing such a large reraise
