How can you win in less than 10 moves?

Ok, so I have a question for you. How can you possibly win a chess game in less than 10 moves, because I just don't know how can you do that.

please answer because I really want to know this thing because I think that is impossible

unless your opponent is bad

You can if your opponent allows you to. Like here: she shortest possible win, that implies very bad play from White:

Otherwise, of course you can't force a win in any number of moves, when your opponent plays ONLY very good moves. Would that be possible, that would be the end of chess competition.

There is also the scholar's mate.

Or really anything like that.

It's also called the four move checkmate

There is some opening traps that you can try to mate in <10 moves. Fried Liver Attack is the most popular

Also if your opponent are silly, you can try the Scholar's Mate(also called "4-move Checkmate")

But I think you should learn how to play a game instead of just looking for fast checkmates. In higher ratings, your opponent WILL NOT fall for these trap

I am a chess noob, but just won in 7 moves, my opponent however enabled it.

I'm not a really good a really low elo so I won in 10 moves with 99.2% accuracy, here's the game
