Because they want too.

To play this badly requires beginners on both sides.

lol

I believe the Marshall Defense (correct me if I'm wrong someone) is basically that with a knight sac trying to tempt the other person into it.

  by narutofanforever Why do most beginners play this?

You mean as White or Black?

Both

in order to develope the black bishop to g7 while the knight goes to e7 after that it repositions itself at f5 after the pawn exchange.

taking on e5 is a gambit, it has been proven by an idiot that black can mate in 23, but it has never been run into a computer analysis.

How to mate in 23?

If White plays accurately.

23 moves, narutofanforever?You are a stronger player than me,but never thou shalt make this possible against me,lol!

respect!

White thinks it's a good idea to go for a quick kill by launching heavy pieces first, and Black doesn't know enough to prove him wrong.

Bd6 is the best against it.

The recommended line has black playing g6 on his next move anyways, so I would guess that they looked it up one time after falling for the Scholar's Mate, but don't quite remember it.

Thisis a funny opening played by kids quite regularly, as you know the less serious chess player who plays once in a while would like to launch their weaker pieces out first, to put immediate pressure.  That is why Qh5 is played.

g6, why?  Well, the less serious chess player thinks 'take out their queen'.  But what they always get caught out by, is the Qxe5+ take, that loses their rook. My dad (as a kid) and my grandad would occasionally play chess with each other (they were not serious at all!) and my dads white, e4 e5 Qh5 g6 Qxe5+ was my dads favourite party trick.

Ah, I remember when I fell for this as a beginner.

Nakamura might have something to say about that!
