dangerous turn against LAG
 

BB is the LAG. He's not a re-raising maniac but he's aggressive enough that I have to call down if he raises me. He will also call with any piece of the board

Re: dangerous turn against LAG
 

Having a bad session? Seeing ghosts under the bed? That's a bad turn card against anyone. You still have outs, bet and go from there. Against a lag if he c/r's I just call down. Against anyone else I might call a raise and fold UI on the river. But regardless, headsup I think this is an automatic bet.

Given your read I can't see the value in checking through.
