Preflop: Hero is BB with J[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/club.gif[/img].
UTG calls $0.25, <font color="#666666">1 fold</font>, Button calls $0.25, SB completes, <font color="#CC3333">Hero raises to $1</font>, UTG calls $0.75, Button calls $0.75, SB calls $0.75.

I have been raising to $1.00 with a wide range of hands from AA to 72 offsuit, so I didn't want to change that and have them be suspicious of me actually having a hand. Last time I raised to $1.50 with AA I got no callers, so I decided to keep more people in the pot and use my decent post-flop play to my advantage.

Flop: ($4) 9[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/spade.gif[/img], 5[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, <font color="#CC3333">Hero bets $4</font>, UTG calls $4, Button folds, SB calls $4.

I led here for full pot because if I lead for half pot here, there's a great chance that I will get bluff raised with someone holding the lone A[img]/images/graemlins/spade.gif[/img]. Naturally, the option was to pot it, and severely re-evaluate my hand if someone comes over the top. To my suprise I got two callers, and I am putting one of the two one the A[img]/images/graemlins/spade.gif[/img], probably UTG because he's tilting and trying to hit a big hand. He's blown through quite a few buy-ins.

Turn: ($16) K[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, <font color="#CC3333">Hero bets $10</font>, UTG calls $10, SB calls $10.

I give up. I just give up. Maybe I should have potted it here, but that's pretty much putting me all in. When I get two callers, I'm very unsure if my hand is good here. I still contend that at least ONE of them is on the A-high flush draw.

River: ($46) T[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, Hero checks, UTG checks.

If they were on flush draws, they sure as hell aren't calling a third barrel. I check intending to call an all-in if necessary, but fully expect UTG to check with his missed flush draw into a 3-person field, who are relatively pot-committed at this point. A made flush would have pushed the turn.

Final Pot: $46
