15 30 AA things don't go according to plan

[Robk]

party 4 handed.

player info: CO is a lag. given that the game is 4 handed and fired up though he's only a couple notches above me on the lag scale. his aggression will generally be backed by something, ie he won't spew chips bluffing if he has nothing. he's up about 2k in the last hour.

sb hasn't been here that long. seemed typicial at first, but is coming unglued as the LAG takes three or so good pots off him.

lag raised in the co, sb called, i reraised in the BB with A [img]/images/graemlins/club.gif[/img]A [img]/images/graemlins/heart.gif[/img]. The lag capped, sb and I called.

The flop was 8 [img]/images/graemlins/club.gif[/img] 7 [img]/images/graemlins/heart.gif[/img] 3 [img]/images/graemlins/heart.gif[/img]. We both checked to the CO who bet. The SB checkraised, and I called the two bets cold. The co made it 3 bets and we both called.

The turn was the Q[img]/images/graemlins/club.gif[/img]. The sb checked and I bet. The CO raised. Now the SB made it 3 bets.

What's my plan here and how did I do so far?
