SB (t8590)
Hero (t3420)

Pre-flop: (9 players) Hero is BB with T[img]/images/graemlins/diamond.gif[/img] K[img]/images/graemlins/club.gif[/img]
7 folds, SB calls, Hero checks.

Flop: J[img]/images/graemlins/club.gif[/img] K[img]/images/graemlins/spade.gif[/img] 4[img]/images/graemlins/spade.gif[/img] (t400, 2 players)
<font color="#cc0000">SB bets t200</font>, Hero calls.

Turn: 6[img]/images/graemlins/heart.gif[/img] (t800, 2 players)
<font color="#cc0000">SB bets t400</font>

I expect villain to complete with basically any hand, and once I check in the BB, I expect him to bet this flop most of the time.

a) On the flop, is just calling preferred, or should we raise?
b) Raise the turn?
c) If we raise to 1200 and he shoves, do we call?

tytyty, input appreciated
