Snapping off a bluff? (or, ATo from the SB confuses me)

[yasher]

I'd like comments on every street.

Villain's 77/7/1.1 over 200+. My relevant notes on him: calling station donk / bluffs rivers when checked to / overbet pushed unraised flop w/the nuts.

Completing ATo here standard? Don't think I'm comfortable playing it in a raised pot from horrible position, so I'm completing and hoping for a flop that looks... something like this?

Preflop: Hero is SB with A[img]/images/graemlins/spade.gif[/img], T[img]/images/graemlins/club.gif[/img]. Hero posts a blind of $0.10.

<font color="blue"> How's the bet size? If he's got the flush, I think he's pushing here, and I can safely fold... but that's putting a lot of strength in my read. </font>

Hero checks, <font color="#CC3333">MP bets $5.44</font>, Hero calls $5.44.

<font color="blue"> So, 4-card flush is out there. My hand beats a bluff... </font>

With another villain, I think I can block that river for ~4 and fold to a raise, but I expect this guy to bet with almost anything here, and I can beat the kind of raggedy two pair hands he often ends up with...

Any comments much appreciated.

Hand is standard but I fold the river. What can he have called you down with that he needs to bluff?

Jam,

Him? A Jack.

i dont like hand postings like this. this is entirely read dependent. your read says hebluffs the river when checked to. you checked, he bet, you call. do you plan on being ahead more than 14:5.5?
