Value Bet This River?

[bobbyi]

I've been raising my button a lot and this is only the second time SB has three-bet. The last one didn't get shown down (I folded before river). In general, he hasn't been getting out of line. His stats are something like 77/9/1. BB is like 40/4/1. If they have been paying any attention at all, I'm sure they think I am quite aggressive.
