I have no read on this guy but I didn't see how leading into me with his pot overbet on the turn after check-calling the flop could be anything but a bluff (though the possibility of KQ, KA, or two-pair worried me). Anyways, assuming no read, would you make this call? It was a $90 call to me with $140 in the pot, and I'd say there's more than a 50-50 chance that this play is a bluff. I do sometimes get myself in trouble misreading overbets like this though.
