Another silly fold?

[lil feller]

B&M 10/20 (I know, I know small stakes. If nobody here feels like responding, i'll repost it there...)

SB is clever TAG, only other "above average" player in the game. UTG is weak/tight with very predictable standards on all streets.

Preflop:

UTG limps. This means she doesn't have a big ace, and if she has a pair its 8's or smaller. Likely range is 88 on down, QJs, QTs, JTs, and other small suited/unsuited broadway cards. Folded to me in the h/j, I raise with A9o. Folded to SB who calls. BB folds, UTG calls. Three of us.

Flop:

9-7-5

SB bets. UTG calls. I raise. SB 3bets UTG calls and I fold.

Standard?
