since no one is giving a real response i will...

1. ...cant be that bad since he cant call with AK right... not much history to say what he does with kk or something, but it cant be that bad, i dont mind it

2. free money, why not... doubt an A ever calls unless he really knows you, its not like you have a bunch of 6s in your range though

3. meh, id want some sort of read that he isnt a post flop station as soon as he gets a hand that he likes but that river bet is pretty dam weak, if he does this with nuts to make you spazz then gg but more likely he has 88/55/A6s, right? which should fold np...

4. seems dumb, if u wanna milk the fish bet smaller? or check behind if not. i assume this is for value and you hope he has QcXc? seems bad since i do this (as villain) with like AJ sometimes where villain wont call with worse so i check to pick off a bluff
