2/4 Semi bluff turn ... Bluff river?

[Rotterdaum]

Villain seems like a tightish regular. In the session I've already tangled with him and came out on top mainly due to set ups. I don't think he views me as unreasonably loose/out of line.

I thought this hand was weird because of his call on turn.
Who likes turn? Who fires river?

Pot is about $400 on the river and he has $230 behind
