I play in 1/3 game fairly regularly in an underground cardroom. Here are three hands I played the other night in which I lost big pots. I'm wondering if there's anything I could have done differently (trust me, I'm sure there are plenty of things to think about). I've noted some thoughts following the descriptions of the hands. Any feedback would be much appreciated.

Game was full ring 10 players. About half TAG-style players, and half action players. I was trying to play tight, and was only playing about 6-7 pots every hour.

1) I'm in the CO holding 7/7 with $200 behind. Folds around to player directly to my right. He raises to $15. He's been raising and reraising all night, absolutely crushing the game, and doesn't like to fold hands even if he's beat. He's got me covered, and I think there's a decent chance that if I hit my set, I'll bust him. I'm also confident that at least one other player behind will call. The BB cals. Pot is $46.

Flop is QQ7. Not the nuts, but I'm pretty sure I'm crushing the board. BB checks, player to my right c-bets $25. He's been a serial c-better. I decide to call, planning to: 1) bet the turn if no one else does, or 2) reraise the turn. BB folds. Pot is now $96.

Turn is Q. Not the card I wanted to see, but I feel that I can take hands like AQ, KQ, and QQ out of my villain's range. He fires $50. This is a stronger bet than I anticipated, and my instincts are telling me to fold, but I instead raise all in. I don't call because if I call, I will essentially have put 50% of my stack into the pot for the hand. Villain calls and flips over KK. No 7 on the river.

What I could have done differently:

a) Raise the flop. When villain bet $25 into me, I'm thinking I should have raised to $100 straight. However, if I raise him right there, I'm pretty sure I lose him. He said after the hand, "If you raised the flop, I was folding." Now, every poker player says they would have made the right decision once the cards have been revealed, but I really didn't want to take down just one $25 bet on such a big hand.

b) Fold the turn. At this point, villain bet $50 into me. While I could probably take AQ, QQ KQ, QJ, and Q/10 out of his range, at this point I was still losing to AA, KK, JJ, 10/10, 9/9, and 8/8, and any Qx trash hand, and villain would have raised any of those non-Qx hands the same way. So, while I had him crushed on the flop (about 85% equity to 15%), I was almost drawing dead on the turn, and could have recognized this based on his bet size.

2) Again, I'm in the CO holding AK. One player from EP limps. He is new to the game, and he was confused about what "posting" is, so I'm not sure what to make of him. The second player raises to $15. This guy runs the game, and he's a tricky player - loose, aggressive, and will play with almost any two cards (opening range of all pairs, all paint card combos, all Ax's, all suited connectors, and all suited one-gappers from any position). I decide to call with AK, ready to dump it if I don't flop anything, and someone's betting into me. Also have a mind that I might be able to stack the game-runner, who has lost a few big pots and is steaming hard. Limper smooth calls from EP.

Flop comes Q/10/10r. Both players check; I check as well. I'm sensing that someone has a hand here, but not sure who.

Turn comes J, giving me the nut straight. Both players again check. At this point, I don't have the absolute nuts, but I'm pretty strong, so I bet $25. EP reraises to $60. At this point, I want to give him a narrow range: J/10, JJ, QQ, A10, 10/10; however, I also recognize that he seems new to the game, so I think he might be holding AQ, AJ, AK as well, or maybe even KQ, KJ, K10. Essentially, as Dan Harrington might say, I'm either way ahead or way behind.

Game runner tanks, and then finally lays it down. I think about those above possibilities, and based on the way they hand was played, discount 10/10, QQ, JJ, and J/10 pretty quickly. I think he's either holding a queen, jack, or 10, and decide to shove. He calls and turns over QQ. I'm drawing dead. The game runner says he laid down a 10.

What I could have done differently:
a) Reraised preflop. Probably would have heard from the early limper with QQ (I think he would 4-bet, or even if he called, that would have indicated some serious strength).

b) Bet the flop. Sure, I hadn't made anything at this point, but a bet on the flop would have probably inspired at least one of the other players to reraise. I would have laid my hand down at that point having only lost a small probing bet.

c) Not making a shove on the turn when so many hands might have me crushed. Nuff said.

3) On the button with JJ. Same guy who limped with QQ limps into the pot. It's about two hours later and I've found villain to be a conservative player who will limp with a lot of speculative hands, but barrel hard when he hits something. His stack has been up and down all night, but mostly up. I raise to $12. BB calls and EP villain calls. BB is a spewy player who will chase any sort of draw. Pot is $37 dollars.

Flop is 10/4/3r. BB checks and villain checks. I bet $25 dollars, about 2/3 of the pot. I'm thinking that either everyone folds, or I get a caller who either hit a 10 or has a smaller pocket pair. BB folds and villains tanks, tanks, and calls. Pot is $87.

Turn is an 8. Villain checks. Based on the long tanking session and this check, I'm convinced I have the best hand, I bet $60, hoping for value. He tanks, tanks, tanks, and finally calls. Pot is now $207.

River is a 9. Villain checks again. I decide to check as well and show down the hand. I announce, "I have jacks," and villain responds, "Oh, sorry man, I have pocket 9's." $200 pot sucked away from me.

How I could have played differently:
1) Bigger turn bet: Not sure this would have mattered. Villain seemed really content calling with 9s the whole way, even though it should have been pretty apparent that he was beat. Honestly, I don't understand his call on the turn. I mean, if the nine doesn't come I take down a big pot, but honestly, facing two bets with an underpair to the top card on the board, I would think most tight players would fold.

2) Bigger flop bet: But again, not sure this would have been a good play. I felt good about my hand, and wanted to bet enough to make hands like AQ, KQ, KJ, QJ fold, but not enough to make 10X fold, or enough to make players give up draws with hands like 5/6 or A2.

3) This may just have been a hand in which I was unlucky.

Hand 1: fold turn
Hand 2: bet flop if you call AK IP
Hand 3: wp

in hand one, he can't have QQ, but why do you say he can't have AQ KQ QJ QT?
