$400NL at FTP. First let me say that I bluff very little in general.

#1) I raise to $14 with [8h]. The button calls. Hes a bit fishy but not horrible. Ive seen him limp Q6s UTG so he likes his flushes. We both have over $500.

Pot $32. Flop [7s][4c]. I bet $32 and he calls.
Pot $96. Turn . I bet $60 and he calls.
Pot $216. River . Fire again? How much?

#2) I limp [Jc]. SB raises to $14. I call. I know this is a very weak play, but this guy is horrible and I have position heads up so I decide to take a flop. He has only $170

Pot $30. Flop [4d][2c]. He checks. I bet $20 but he calls.
Pot $70. Turn . He checks again. Im pretty sure he has AK. I bet $45 but he calls again.
Pot $160. River is another blank. He has $90 left. Im 75% sure he has AK, but the problem is that he WILL call me with any pocket pair. Ive seen him make a horrendous calldown with 88 with 3 overcards on the board including an ace and of course the other guy had AQ. But in that hand, he wasnt the preflop raiser. I cant think of any hand he would raise preflop with and not bet the flop except AK / AQ.

Do I put him all in here?
