Why you would shove 66 preflop? Are you betting value or
bluffing? In any case I think isn't a correct play. If you make everyone folds, you don't win a expressive pot, unless in the final of a tournament, when the blind are high. If you get called, you will be in a coin flip or worst in most of the hands. Who would call your shove? Who has a good hand to do it.
Even in a good spot, in late position against tight players, you don't need to shove to steal blinds. A good raise is enough.
The only situation that I think it must be done is when you are short stacked.
But if you believe you are lucky and don't believe in
odds, go for it. A lot of people do it online.
