1/2 questionable line - how do you eat yours....

I don't have the hand history but I know how it went down :

Villain is SB and we have no read as he has just sat down.

1/2 Prima Poker ( 6 players )
Hero has : K [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/heart.gif[/img]

UTG limps, folds to Hero in Dealer who raises, SB autoraises, UTG calls, Hero calls.

Flop :
K [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/club.gif[/img] 4 [img]/images/graemlins/spade.gif[/img]

SB Bets, UTG calls, Hero calls

Turn :
4 [img]/images/graemlins/spade.gif[/img]

SB Bets, UTG calls, Hero calls

River :
2 [img]/images/graemlins/heart.gif[/img]

SB Bets, UTG calls, Hero calls

Anyone play this differently, and why / how?

True.
