Well I auto-bet out, but I was wishing there was an Undo button right afterwards. I'm convinced now that checking is better. Anyway, here's what happened next:
Party Poker 1/2 Hold'em (6 max, 6 handed)
converter
Preflop: Hero is SB with Q[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/spade.gif[/img].
UTG calls, <font color="#666666">
2 folds</font>, Button calls, <font color="#CC3333">Hero raises</font>, BB calls, UTG calls, Button calls.
Flop: (8 SB) K[img]/images/graemlins/heart.gif[/img], J[img]/images/graemlins/heart.gif[/img], 9[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">Hero bets</font>, BB folds, UTG calls, Button calls.
Turn: (5.50 BB) Q[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
Hero...
So now, nobody's shown any strength, I improved, but there's a four-straight and an overcard on board. Button will call down with a J,9,A-high or the 3 of purple horseshoes, but UTG is still hanging around and I'm pretty readless on him. So do I bet and fold to a raise? Or just check/fold now?
