(live $175) Time to bail out of a stop-n-go?

[Slim Pickens]

Mirage live $175 SNG, ten players start, payout 70%/30%

2000 starting chips, 4 players left

Hero = BB
The Button is a fairly poor player. He got his stack with a great run of cards paid off by even weaker players, plus a few suckouts. He has been raising my BB fairly frequently. I've been folding a lot more than normal to his raises due to a glut of indefensible BB hands. My handle on his raising range isn't great, but I'm sure it includes any pair, any ace, any two Broadway, and maybe some other stuff. I know he's capable of laying down a hand as good as top pair, but that was against someone else and I'm not sure how much credit he is going to give me postflop since I doubt he even remembers me playing my one hand.

The table has turned fairly aggressive. I am perceived as some sort of retarded maniac because I keep pushing for ~10 BB. People limp... I push... profit. There was a lot of "I'm gonna catch you, you little punk," going on every time I would push. I showed down one hand in a small pot very early on, then nothing else.

This hand is a stop-and-go from the start. I had yet to pull one of these and now seemed as good an opportunity as I was going to get. I'm still convinced it was the correct strategic decision for the hand but my tactics might have failed me.

Hero ???

Can you pull the trigger on that flop? Can I not pull the trigger on that flop?
