Another dumb (semi)bluff

[sweetjazz]

FT 8/16 game, currently 5 handed. LAGgy player limps UTG, folded to me in the SB with 9d 5d, I complete (meh?), BB checks.

Flop is Jd 7c 3c. I check with the intention of folding. Surprisingly it gets checked around. BB is TAGgish. Both players are basically never checking a pair on this flop.

Turn is the 7d. I check, BB checks, UTG bets, I raise, with the intention of betting every river.

I kind of feel like check/folding, bet/calling, and check/raising the turn all have some merit here.
