Ugh, what a gross river. It's a very frustrating lay-down seeing as he obviously didn't even have the Adxd that would've likely reraised that flop turn. I think I call this river read-dependant (If I think he's capable of making plays) enough, but we don't beat anything but a bluff. Nothing else is possible, he didn't slowplay a lower set or AK or blah, gross hand. At least the overbet lets you get away from it BUT the overbet is so suspicious, but it's probably just a tool that thinks you're gonna pay him off no matter what the bet. The problem is if you call this bet, you indeed were giving him the right odds to chase his small flush.

More I think of it, more it's a fold.
