Ive played 72 when i was in the small blind, the bigblind doubled the blinds, everyone else called, so what the hell, i did too. Flop comes 772. I check, BB goes all in. everyone folds, I call. BB had AA. It is too obvious to play those hands. It doesnt make you look lose, it makes you look like a jackass, because everyone who is tight will sometimes play those hands, and show them, to try and show tehy are not tight. But the 72 is too obvious.
