Variance for Variance sake?

fairly average table, meaning very donky, but they error more on the side of calling too much, so no great chip accumulation opps so far.

25/50 level, I have 1100, average is 2100 or so, about 90 left, 30 pay, but only FT matters.

AQs in BB
Folded to passive button who limps, SB who has a gazillion chips and has shown aggression once in last 45 minutes, and it was with top set. This is the 1st time he has raised PF, he has however called down with mid pair and 2 over cards.

He makes it 150. 250 in pot. I had notes on SB as being uber-tight PF, so I think AJ+, 88+ looks about right.

Stop and go: probably going to take a scary flop for him to fold

Play it out: I do have position, and enough chips to have post flop F.E.on the right board

Push: most likely a slight -CEV play, but my best chance to double up.

I pushed, thinking that I think that having 20x once is a good bit better than having 10x twice at the next level. Any thoughts?
