25NL hits river -- what's your recommendation?

[Javanewt]

Sorry about the format, and I’m trying to remember details as best I can.

No reads. I’m fairly new to table.

Ultimate Bet, 25NL, 10 players

Villain in EP ($15) bets pot, one caller from MP. Hero ($25) is button with 9T[img]/images/graemlins/spade.gif[/img] and calls. Everyone else folds.

Flop comes KTXr (three players)

Villain bets .25 into a ~$3 pot

MP calls, hero calls

Turn is a blank.

Villain bets $1 into a ~$4 pot.

MP calls, hero calls

River is a T (no flush).

Villain bets $2 into ~$7 pot.

MP folds

Hero?
