Actually, scratch what I said before, I didn't realize that this raise isn't even that big after all. He had $20 and had already committed $6. So you essentially raised 14 on top of a $20 pot. I would say it's a good push, ignore my first response
edit: although I still think you are wrong about wanting 77-TT to fold to your bet. You want action from any hand under QQ, as you'll have 15 outs and be about 56% to win. When you're a favorite to win, you want them calling. It doesn't matter if they have a better hand now, you have the best hand because you will be seeing 2 more cards, and the majority of the possibilities will give you the lead.
