[bblock99]

Here's a recent hand at 1/2 6-max.
Hero is dealt A [img]/images/graemlins/heart.gif[/img]A [img]/images/graemlins/club.gif[/img] in MP. UTG open-raises, hero 3-bets, CO and button fold, SB calls, BB folds, UTG calls.

Flop:K [img]/images/graemlins/diamond.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]J [img]/images/graemlins/club.gif[/img]
SB checks, UTG bets, Hero raises, SB calls, UTG calls.
After the SB cold-called two bets, i was sure he was on a flush draw, and i was almost sure that UTG had AK.

Turn: 10 [img]/images/graemlins/diamond.gif[/img]
SB checks, UTG checks, and Hero checks on the read that the SB had the flush. I would have bet had i had the ace of diamonds.

SB immediately bets, UTG and hero call.
SB turns over 5 [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/diamond.gif[/img] and UTG had A [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/club.gif[/img].

How'd i do?
