NL600 Trey Barrels, somewhat interesting river?

[Burdzthewurd]

NL600 5-handed

Villain and I both have $600. 2nd orbit at table. He's an unknown but has a very similar SN to another player that I've played against at same stakes and from observing the table before sitting has a very similar style, so it might be an account on a different skin. If that is the case, he is able to fold overpairs/TPGK, doesn't slowplay big hands after the flop, and isn't going to bet/call flop and float turn with something funky like a gutter - basically I'm 99% sure river is not a good card for him and he won't show up with JT against me. If he is a total unknown, this is probably suicide?
