game is generally semi-tight, and somewhat passive. not a lot of bluffing or stealing going on. there are no players here that are loose for their whole stack. fair amount of limpers some hands but raisers and raise-callers have generally shown very good hands. social table- lots of chat. my image is very tight/solid. i've shown great hands every time ive raised. I know that when the blinds go up further, i'm going to have some good chances to steal blinds and increase my stack.

6 handed. blinds are 50/100. my stack is 1070. there is no one in the hand with a shorter stack than me.

I'm on the button with Q9o. 2 limpers to me. I push.
Comments please. what i want to know is, how much on average am i gaining here, and is it definitely worth risking right now when I may have better pot odds on my bluffs when the blinds go up?
