TT, two overs but hits a set in river

[winky51]

Seems logical to me. If I was SB I can't see calling down with AJ here or J9 unless they were hearts. Or cold calling with QQ or KK. So his hand range is small. I would give credit to 2 pair and he is afraid you have AK. KT?

I'd call the 4 bet, of course, grumbling if he shows something like AJo or J9o... But be happy about it since this guy now is a fish.
