I never seem to employ the turn raise/free showdown play correctly, but I don't think this is a spot for it here.

MP is already gone, so at best you're punishing a semi-bluff, or charging him if he's got 3-5 outs. At worst you're getting 3-bet (are you comfortable folding to a 3-bet here? I'm not).

I like a call down from this spot, since I don't risk folding a worse hand or donating to a monster, though I could see betting this river after you just get called on the turn, looking for a call from JJ/QQ (and folding to a check-raise).

edit: oh laugh, I didn't even bother reading the preflop action. doesn't look like a limp reraise to me either.
