PL: I always bet the pot preflop with TT or JJ, hoping to get down to one opponent. Chances are if I do this that I'll be winning when the flop comes. Exception is if there's been a raise from a player with low PFR, in which case I flat call.

After the flop:
If I'm first to act I bet fairly big again unless the flop is really bad (has both an A and a K). Most of the time they'll fold because I represented a big pair before the flop. (If I'm against a real calling station I'll bet much smaller after the flop and hope I don't get reraised).

If I'm last to act and there's one or more overcards out I get the money in unless the other guy bet the pot, in which case I fold without a set just like any other PP.

If I'm reraised at any point post-flop I look to fold unless I have a set or a big draw (e.g. 9TQ for jacks).

See also my other post about pairs in this forum for one specific situation which may be relevant.
