Can't help but have second thoughts after things like this happen.

Preflop: Hero is UTG+1 with 8[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/spade.gif[/img].
UTG calls, Hero calls, <font color="#666666">3 folds</font>, Button calls, SB completes, BB checks.

Flop: (5 SB) 8[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, BB checks, UTG checks, <font color="#CC3333">Hero bets</font>, Button folds, SB folds, BB folds, UTG folds.

Final Pot: 3 BB

With no likely draws out there, is this a situation where it would be correct to check the flopped set?
