Preflop:
CO raises, SB 3bets, CO caps, Sb calls.

Flop 9 SB: K /images/graemlins/heart.gif 8 /images/graemlins/spade.gif 8 /images/graemlins/club.gif
Sb checks, CO bets, SB Raises, CO 3-bets, SB calls

Tilt?

Well it far from standard. Once SB 3-bets the flop CO is done IMO and should fold. Assuming the flop call, the turn call is pretty bad.

Edit: I got mixed up there. CO's flop 3-bet is very bad.

preflop cap, flop 3 bet and turn bet suck

I liked his preflop cap; It discourages people from trying to isolate him and disguises his hand well.

I like his preflop cap against some TAGs (depends on his reads). If the TAG he is up against is being aggressive enough in steal situations that the cap is good, he should call the flop c/r. Maybe raise turn?
