Need some input on this hand.

#1.Bit manical here post flop?

#2. Do we bet this river or is this one of those you'll only get action from a better hand scenario? Sorry about the format it's on Tridonka so keep in mind usually people are almost always playing any A as well.

CO is a portrait of a station. 73/4/.06 and goes to the SD 49% of the time so all I can really put him on is the fact that he holds 2 cards. Button is relatively unknown (less that 40 hands) but what I have basically is 46/17/1.6
