I'm Flush Nuts, Board Pairs On River

[Twitch1977]

Sorry for lack of reads, I played this hand a few days ago [img]/images/graemlins/frown.gif[/img]

Party Poker 0.5/1 Hold'em (8 handed) converter

Preflop: Hero is MP1 with K[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/heart.gif[/img].
<font color="#666666">2 folds</font>, <font color="#CC3333">Hero raises</font>, <font color="#666666">3 folds</font>, SB calls, <font color="#666666">1 fold</font>.

Flop: (5 SB) 6[img]/images/graemlins/heart.gif[/img], 3[img]/images/graemlins/heart.gif[/img], 2[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">SB bets</font>, Hero calls. (?)

I just called this bet, the pot was still small and I wanted to wait and raise the turn, I thought the odds of him folding outright were just too high with a one suited flop. Is this proper? Or is raising the better play?

Turn: (3.50 BB) Q[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">SB bets</font>, <font color="#CC3333">Hero raises</font>, SB calls.

River: (7.50 BB) 6[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">SB bets</font>, <font color="#CC3333">Hero raises</font>, <font color="#CC3333">SB 3-bets</font>, Hero ...

Is this an easy cap? Or am I better off just calling when the board pairs and he all of a sudden pops a 3-bet?

Thanks
