Hand 1:

Preflop: Villian has 160$ and I have him covered. He is in SB running at 20.4/2/0.1 after 225 hands. So he is quite quite passsive. I'm in MP with and I raise it up to 8$. SB is the only caller

Flop: Pot: 18$, he checks I bet 14$ he miniraises to 28$. I decide to call to see turn action
Turn: Pot 78$, He leads 56$ leaving 65$ behind...I decide to push thinking that if river comes K or Q i wont be able to fold anyways so i wanna get my money in now since im stacking off anyhow...I push he calls...Question is...Given that you know that his range is only AT, TT, AA, 88, AKs/o do you fold turn? Thing is that I' m kinda favorite even over that range(even if i exclude overplayed AQ and A8, T8...So is it a cold deck to lose on this flop or should I consider folding? My aggro is 3.0+ so no opponents would fold even A8 vs me in this situation

Hand 2: I'm not sure what line to take in this hand..there are several but im not sure which one is the best
Preflop: I hold , MP limps and I raise it to 10$ OTB and BB is only caller. I have 200 and he has me covered. I have less than 20 hands on him so I have no reads
Flop: Pot: 23$ he checks/calls my 18$ CB
Turn Pot: 59$ villain leads for 44$. Now im thinking that he might have flush but I might have a redraw with my king. So i call
River Pot 147$ villain bets again 44$, hero?
His turn lead was strong, should i consider calling it only if I have the ?

Hand 3: This is just general question? Should i ever be considering folding KK preflop? I've been running my kings into aces a lot lately, like 6:1
(6 times i ran into KK with AA, once my AA trapped KK) and in most situations they made a retarded miniraise for 4-bets and every single time they had AA..but i let myself still get stacked..Now my preflop aggro is 2.5 so i doubt that they can fold kings vs my aces.
