Overplaying/Underplaying Overpairs

[poboys]

In reviewing my play in PokerTracker, I feel like I've been playing my 99-JJ hands poorly--especially when the flop is unders and the turn brings an over. Either I play too hard when behind or miss bets by letting chasers off the hook.

Here's an example hand:

Villian is 12/5.5 over 144 hands (not all of them from this session). Rated as a $-bag.

Hero is 10/5 at this table (say 60ish hands) and is down about 1/2 a buy-in.

Anyone play this hand any differently (esp interested in turn suggestions)?

this guy is pretty tight, looks like a set. i could fold to the turn c/r.

I like the play up until the turn. Here I think it better to check call down to the river.
