I think this is standard

I'm a wimp, but I don't bet that river, and if I do I don't call a raise. His turn bet is a hand that doesn't want to get checked through, and your raise tells him you have a BIG pair. He has to have a better hand to c/r this river, I just can't see calling the raise being correct. If he's tricky enough to c/r with a worse hand, I don't bet the river.
