What is the standard line for TPGK against an unknown at 50NL? Opponent has been aggressive in his first orbit at the table. I guess I should check the turn here. No real great draws out, but I don't know if opponent plays total crap yet. I want value from 99+ & Ax, but would like to save $ if I'm out-kicked. Is this a clear turn check?
