Four hands: played well, or not so much?

[SpaceAce]

The villains in these hands are generally donkish but not exceptionally maniacal. I'm warning you up front, I lost all these pots. I'm not looking for sympathy or "[censored] happens", I'm looking for ways to maximize my edges when ahead and save bets when behind in these spots.


Hand #1:
Three-handed $3/$6
I open UTG/on the button with TT. Small blind three-bets all-in. Big blind caps (I really don't believe he's strong here, I think he's trying to squeeze me out, but whatever), I call.

Flop: 663 or some trash.

Big blind bets, I raise, he calls.

Turn: blank trash

Big blind checks, I bet, he calls.

River: Jack

BB checks, I... check behind?
========================================

Hand #2:
Six-handed $3/$6.
Folded to me on the button with J[img]/images/graemlins/spade.gif[/img]T[img]/images/graemlins/spade.gif[/img]. I raise, small blind folds, big blind calls.

Flop: Tx2[img]/images/graemlins/spade.gif[/img]8x

Big blind bets, I raise, big blind calls.

Turn: 5[img]/images/graemlins/spade.gif[/img]

Big blind checks, I bet, he calls.

River: Q[img]/images/graemlins/heart.gif[/img]

Big blind donks, I... call?
========================================

Hand #3:
Six-handed $3/$6.
UTG+1 raises, I three-bet with KK in the cutoff, small blind folds, big blind calls, YTG+1 calls.

Flop: 44Q rainbow

Big blind checks, UTG+1 donks, I raise, big blind folds, UTG+1 calls.

Turn: offsuit 3

UTG+1 donks again, I... raise?. He three-bets, I... call down?
========================================

Hand #4:
Heads-up $3/$6.

I raise on the button with A[img]/images/graemlins/diamond.gif[/img]Q[img]/images/graemlins/diamond.gif[/img]. Opponent three-bets, I cap, he calls.

Flop: AQ3, one spade

Villain bets, I raise, he three-bets, I cap.

Turn: 7, putting out two spades

Villain checks, I bet, Villain calls.

River: 7

Villain checks, I bet, villain check-raises. I'm having a really hard time putting Villain on a 7, here, but what is he check-raising with? I'm sure I'm beat because I'm always beat, but this is an easy call, right?
========================================


Results + an additional question or two:
Hand #1: <font color=" #FFFFFF">SB has ??, BB drags it with J8o. Should I bet/fold the river? Bet/call?</font>
Hand #2: <font color=" #FFFFFF">BB takes it with Q3o. Should I just start folding to these river donks when the river is an overcard?</font>
Hand #3: <font color=" #FFFFFF">UTG+1 has T4s. I put in a lot of money bad here which is very unusal for me. Go into calldown when he donks the turn? Fold to the three-bet?</font>
Hand #4: <font color=" #FFFFFF">Obviously, Villain has A7o. This is never a fold, though, is it?</font>

I've had a BUNCH -120BB to -150BB sessions (not multi-day runs, individual sessions) in the last two months. I am either running worse than anyone in the history of poker or I am spewing tons of chips in these lost pots. Could I have reasonably folded somewhere in the hands above, or put in less money without hurting myself when I'm ahead?
