The most effective punch

[Xyei]

Bare knuckles or with a glove? With a glove I'd say uppercut or hook on the chin.

Bare knuckles, a hook right on the nose or throat.

Bill Paisley once said "It's not about the long ball or the short ball, it's about the RIGHT ball. And that's the one that puts your opponent under pressure."

I think that his wisdom could equally apply here.

Thanks everyone.

Is Berbick dead?

He's dead, found him with a machete in his head.

[Verstyle]

I say the left hook. It can catch you and you won't even see it.

[KnockoutTheFat]

left hook to the body

[hardmanbrit]

Thanks guys.

One question: Isn't there an important nerve on the chin that can knock someone out?

[loui_ludwig]

Uppercut to the balls.

[-Antonio-]

The one you dont see.

I think the jab is probably the most important though because even if you're trying to brawl up close or keep a distance, it always starts with the jab.

[Easy-E]

Liver shot is one of the mosts effective punches.
The jab is also extremly effective when utilized properly, one punch can control the pace of the entire fight.

Keep in mind the most effective and most devestating punches are different things.
