Dangerous river heads-up

[onegymrat]

$8-$16 at the Bike. Fair but full table, couple of looseys and a few good players. UTG calls, as do I UTG+1 with A [img]/images/graemlins/club.gif[/img]10 [img]/images/graemlins/diamond.gif[/img]. MP calls, SB (average player) completes and BB checks. Five to the flop.

SB bets, folded to me, I raise. MP folds and SB calls. Two to the turn.

SB checks and I check behind her. All comments appreciated.
