i am not much on pot odds and such....i do consider such things, but i have to remind you that although your Q-7 is probably not a 7-1 dog against any A-A, you could be even more of a dog against a field of 3 other hands to see the flop..i.e. A-A, K-Q, and 8-8....unless this was a very loose, low ante no-limit game or your play was EXTREMELY SUPERIOR post-flop then the correct play is to fold....i feel saving your money to the times when you have a decided edge is the most profitable play....then again, who the hell am i?....best of luck at the tables!
