I know heads up hands are very hard to comment on because a read is everything, but if anyone cares to comment anyway, feel free.

All hands against same guy.

#1) We've been playing for about 15 hands. He seems pretty ABC.

I raise to $7 on the SB / button with [5d]. He calls.
Pot $14. Flop [Td][7h]. He checks and I bet $12. He calls.
Pot $38. Turn . Check / check
Pot $38 River . He bets $25 and I raise to $75. Raise too small if Im gonna try to steal it? Just right?

#2) Im now raising to $7 from the SB / button with anything playable. Hes not playing back and only calling about 25% of the time.

I raise to $7 with TT. He calls.

Pot $14. Flop [5c][3d]. He check / calls my $12 bet.
Pot $38. Turn . he checks, I bet $30. He check raises to $80. its $50 to me and he has another $86. I have him covered. Thoughts?

#3) Ive showed my cards on 2 pretty big bluffs now. We're about 80 hands in which is quite a few heads up.

He raises to $6 and I call with [Jc].

Pot $12.Flop [6c][2c]. I lead $8 and he calls.

Pot $28. Turn . I checked with the thought of a possible really big check raise to make it look like a bluff. The free card doesnt hurt me much since I have the . But he checks behind.

Pot $28. River . I check again with the intention of check raising. Thoughts?

#4) I raise to $7 with 99. He reraises to $23 and I call. Effecftive stacks are $250.

Pot $46. Flop [6h][6d]. He bets $34 and I call.

Pot $114. Turn . He bets $65 and I push. Hes pretty ABC so I dont think theres any way hes calling this w/o an ace. I think he folds even KK based on previous hands and the preflop action. Thoughts? Of course if he has an A, Im dead meat.

It's the pussy sized bet I don't like. Make it 10-12 and I like the check.

What are the stack-sizes and blinds here?

#1) He folded and I showed. Right after I raised, i though it was too small.

#2) I raised all in and lost to a set of 3's. Bad bad play against this guy.

#3) I checked the river as I said. He bet $21 and I check raised to $60. He called with 99.

#4) He folded to my push.

Stakes are $1/$2 NL. I ended up taking about $60 from him before I had to go. Hand #2 was really bad or I wouldve won much much more.

he may have had a little advantage because he sat down right after a busted another guy so he may have been watching me. I wonder if its good to just get up after beating a guy and either only do what this guy did to me which is sit down after he beats a guy but Ive watched him for a while...or to jiust sit at an open table and wait for someone.
