Home game push

[45suited]

11 person SNG. Top two spots pay: 320/120. 17,600 chips in play. Down to 6 handed.

Here's the scenario:

Blinds 200-400. Player A (older woman, I viewed her as a weak player) limped UTG six handed. She had about 3000 in chips. Button goes all in for his last 550. SB folds. I'm in BB with 6s8s. I also have around 3300 chips.

UTG had limped several pots and had folded to a push after limping once before. (Not my push, someone else's.)

I pushed from the BB with 6s8s.
My thought process (obviously) was that if I can get her to fold, I'm heads up in a pot for t1550 and I'm getting 10:1 on my money.

Good play or FPS?
