Troublesome hand from a home game

[ripwalk]

Had an interesting hand come up in my home game sit n go style tournament yesterday.

3 players to the flop - I was BB with 97.

UTG is a pretty weak player who calls down with ace high and low pairs a lot.
SB is a smart TAG-ish player.

Flop comes:

10 9 8

SB checks. I bet 1 dollar. UTG calls. SB calls.

Turn comes 6, giving me a straight.

SB bets 2 dollars, I raise 2 dollars, UTG raises 2 more dollars. SB calls. I call.

River comes a K.

SB checks. I check. UTG bets 4 dollars. SB raises all in for 10 dollars more (the amount now bet covers me, so I have to go all in to showdown)

I... ?

(Sorry about the format. But this wasn't on the internet, and I'm not sure if there is a converter for non internet hands. At any rate, it should be easy enough to follow, and the suits are irrelevant in this hand - ie. no flush draws)

Results will follow.
