CO is some random guy that I don't have much read on but he's unknown and I think I want to play pots with him because I think he's probably not very good

BB is a 2p2 TAG. I'm not going to give his name because I don't know much about his game and I don't want to bias responses. But I know he is solid and a big winner and for some reason I haven't seen him around for quite some time so we don't really have any history. He has been playing very aggressively and his passive line in this hand was unexpected. So now I don't know what to do...
