98s MP steal against TAG CO poster. Too aggressive?

[Jeff W]

Opponent is a top player at 3/6, although i've seen him get out of line against me before post flop. Please rate the pre flop raise and turn bet. Thank you.

I like the way you played this all the way. I like the turn bet. The ten improved what may already be a good hand. Im guessing you were up against two big cards.
