Ok, ive been having a nasty run of running into hands recently so im looking for different options on how to play these hands. Usually my strategy seems ok, but i'd like some other options if possible.

.1/.2 blinds cash table, 6 max.

I get TT in lp, pot has 4 limpers before me so i rasie my standard to 4bbs.
two fold, one pushes all in for a 3rd my stack next guy flat calls it. I think real hard about that call, he has probably 2/3rds my stack if i push. Im guessing the pusher is a lower pp, but this caller is a problem.
Anyway i push and he calls with pocket aces i lose most of my stack.

Am i getting away from this. If im critical, when that guy called it i should have folded it had only cost me 4bbs i was up and doing ok. Yet i sensed the stength of his hand but when ahead aggressive anyway. Also, i considered myself well infront of the first pusher.
Options?
1. Can i get away from this?
2. I thought that with position i would be able to take a stab at winning the pot post flop with TT as my raises are always 4bb and whether im on an overpair or just face cards is probably hard to tell. I hit all flops the same unless its obvious i could be beat. Therefore was raising a marginal hand in TT ok in lp or should i be prepared to start calling with it?

2+.5 sng.
(i think this is a just a plain beat, but i'd like other options)
Im dealt AA in mp. I call as this table has been aggressive in lp so im reasonably satisfied their will be a raise in lp. There is to 4bbs. I call. Its heads up
Flop is all rags so i bet half the pot and other guy pushes all in. I call.
He has Ax spades and hits a runner runner flush.

Ive been flat calling raises recently in the hope of catching someone with a weaker hand (eg no reraise with AK or AA but definatly with KK maybe even QQ) Here i was certain i was ahead, but generally is this strategy right or should i have the guy all in pre flop (i hope that i can get more chips outta him if i just call his raise. eg if he hits cards on the flop (K,Q, J even or an ace ive got him beaten anyway)
is this startegy correct or should i be looking to rerasie preflop or even make a bigger bet post flop?

.1/.2 blinds, cash table, 6max.
Im dealt QQ in ep.
Not sure here so opinions welcome.
raise 4bbs in ep, im trying here to limit the numbers that see the flop. Again ill bet the pot at any over cards in the hope that my hand will be difficult to read.
I get two callers after me.
Flop is rainbow 224.
i bet half the pot to see where i am (i guess thats a sign of weakness as i normally hit most flops with a full pot bet if im infront)Here i actually was at this point. One guy folds one guy calls. Turn is a 6. I suppose thats a scare card. So i check it. He minimum bets it and i call hoping for a miricle river card. Its a Jack. He bets about a quarter of the pot. I fold and he shows the straight with a 3 and 5.
1. Am i right to raise the pot in ep? I need a heads up or short handed situation to have any chance of winning the pot. If i just call and there are overcards i would argue that ive wasted a very good hand. Therefoe i justify my raise from ep.
2. I bet half the pot and i guess i killed his drawing odds. And i had to check the scare card with a potential set on the board as well as a straight. Was this correct? If he'd checeked the turn and then bet the river i may have been tempted to call thinking he was trying to bluff, but because he minimum bet the turn and then made a tantalising bet on the river i guessed i was probably beat. Good read or weak?

Normally i would have pot bet the flop, that may have scared him off i dont know. Is this a correct play? I bet the pot if i think im in front or im bluffing overcards with a good hand, trying to make a read difficult. Also was it correct to lower my flop bet in the light of a pair of twos on the flop?
