Why throw a cross instead of a hook in a street fight?

Fuark my hooks and uppercuts feel much more powerful than my right cross.

Any punch on the jaw will KO someone..

But throwing any punch requires energy and leaves you vulnerable..

Why not play around with the jab, or no punch at all and unleash a stronger punch when your opponent is open?

Done right it's an extremely fast and powerful punch.. I just don't feel as comfortable with it in real life.

Do you think you can one hit KO someone with a right cross in a streetfight?

Lets say you're at a bar and some dude pushes you and his hands are down by his waist...

What first strike are you brahs throwing?

Or would you immediately try to BJJ or wrestle your opponent?
