Been playing 2 hands only in 3 1/2 hour? You must have a REALLY tight image by now.

Why I would push:

1) If it all get folded down, you will still win 2400 and make a profit of more than 50% of what your stack was when the hand started.

2) This being sixhanded and you would be left with 4100 and blinds at 200/400 if you check/folded the hand now. I would act now when I still can do some serious damage.

I am only worried about the 9 as the kicker here since if you do get called, you are likely to be behind but it's hard putting someone on AJ+ without any preflop action and you can probably make someone fold A10 here with your push.
