UTG Limps
I push over the top

My thinking was I have 3.5 BB left. If I can steal this pot it will increase my stack by half or so. It would seem like an easy push, but at the 5+1 when someone limps they seem to call a raise probably 70% of the time (this could be way off for all I know, but that has been my limited experience). Using easybay's program it shows that if you know your push is going to be called about 70% of the time the push is -EV. So what do you do in a situation like this, you can't really wait for a "better" hand given you have 3.5BB left. Do you just wait for a worse hand but when you are the one open raising and not raising a limper?
