1 card straight river raise sex? So wrong that its right?

[ESKiMO-SiCKNE5S]

Just thought i would share a higher stakes hand.... I found this interesting.

10/20 live.
Hero has T[img]/images/graemlins/heart.gif[/img]9[img]/images/graemlins/diamond.gif[/img] in MP2.

Preflop:
UTG limps, UTG+1 limps, I limp, CO raises, Button calls, SB calls, UTG calls, UTG+1 3bets, I cap, CO calls, Button calls, SB calls, UTG calls, UTG+1 calls.

Flop (6 players, 25SB): J[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/spade.gif[/img], 3[img]/images/graemlins/diamond.gif[/img]

All check to CO who bets, button folds, all others call.

Turn (5 players, 15BB): 8[img]/images/graemlins/club.gif[/img]

All check to CO who bets, all call.

River (5 players, 20BB): 7[img]/images/graemlins/club.gif[/img]

SB checks, UTG thinks for a while, playing with chips, UTG+1 donks, I raise with the aim of pushing UTG off his 1 card straight and splitting the pot 2 way with UTG+1. (There is zero chance that CO is calling even for 1, there is a low chance that SB calls with a set maybe?)

Hand Ranges and Reads:

SB - Slightly loose and passive. Likely has flush draw.

UTG - Almost certainly has Tx, but is weak/tight. We know each others games well and he knows i am a good thinking player.

UTG+1 - 99%+ chance of having Tx, probably LRR with a hand like T8-Qs.

CO - Has AA/KK/JJ. Knows that UTG+1 has Tx 100% and will definitely fold regardless of what I do.
