Learning to fold

[scotty34]

BB is a pretty LAG player, but not stupid. Stats are around 40/20

OK, first of all, given that this guy is a LAG, is there still value in the river bet? I would have expected him to raise me somewhere with any A, so I don't put him on that. I kind of sensed the C/R before it happened, yet bet anyways.

Second, do I pay this off?
