5/10nl - flopped set, villain shoves river HU

[Shady Poker]

Villain was playing 26.76/21.08/4.38 over 370 hands when it was 6 handed. He was playing pretty standard and didn't see much out of line. It just got heads up (short stack just sat down and hasn't been a factor) and this is the second big pot, the first one I had a suited connector, called a flop with second pair, turned trips and raised and he folded.

We haven't been playing heads up long. My thoughts on the river are that he probably can't be bluffing here unless he had a hand like flopped 2pair or missed with QJ or something and is trying to represent the straight. 78 is possible but not likely given the line and even though I don't think he can be bluffing, I don't see many 8's hanging around till river here with the exception of maybe T8 or J8, I don't think he calls the turn raise with 98.
