AK 3 bet facing river bet..

[DaCooler]

villians running 85/35/2 over 100 hands although doesnt seem to be as crazy as the numbers are right now, does seem to be a bit of a station. Does anyone bet the turn here? river? i checked the river with the intent of calling a reasonable bet because diamonds were a definate possibility...
