If she's bored enough to be UTG straddling then likely she's bored enough to 3bet AQs, AKs, AJo, JJ+ here. If she folds out all 4 combos of AQs, 1 combo of JJ, and 3 combos of AKo then she's folding 8/44 combos.
We are 32% vs the range she calls with.
So:
( 8/44 * + $161 ) + ( 36/44 * .32 * + $361 ) + ( 36/44 * .68 * -$260 ) =
-$21.73
Seems like a fold maybe?
