50NL Pocket 99's on CO.....correct line? What to bet on turn?

[Johnes Benjamin]

because he barely has more than a PSB left I don't think bet sizing is very important. I could see betting or checking but as long as you are betting this you might as well be shoving.

FWIW I will usually 3bet this pre against a 21/8. If he c/raises me on the flop I can usually lay it down and if he calls the flop I am easily checking behind on the turn.
IMO the hand plays out a lot easier if the raise is made pre instead of on the flop
