Top Two fold on Turn

[HuggyBear]

My first live limit session. After observing the tables, I feel very comfortable sitting down. Very loose game with most flops are seen by >3 players commonly for more than one bet.
UTG has played poorly, UTG+1 has raised, bet flop and called 4th and 5th to non-threatening boards w/AA twice.

Three Limpers, I raise in SB w/ A [img]/images/graemlins/heart.gif[/img]Q [img]/images/graemlins/spade.gif[/img], BB folds, UTG calls, UTG+1 calls, other limper folds.

Flop: A [img]/images/graemlins/diamond.gif[/img]J [img]/images/graemlins/club.gif[/img]3 [img]/images/graemlins/diamond.gif[/img]
