Most people won't fall for that though.
4 move chek mate

That is not a 4 move chek mate.
And that is also not a 4 move checkmate. White has not played his/her 4th move yet, which might go 4. Qf6+? (mouse-slip) Nxf6.

That mate is easy to refute. 3... Nf6 and Black is fine. Beginners should be learning opening principles, not traps.

Some beginners are drawn to opening traps like moths to a candle.
I suspect Bruce Pandolfini's books on Opening Traps and Zaps lite the fire on that, back in the 90's. Nowadays with a few clicks of a button, a beginner can find traps for any line he fancies to play.
Although it's a good thing to know about opening traps for your prefered line, it's not a good thing to just keep playing for traps.
There was a 16 year old in college, not s student, that came to the chess club and had an encyclopedic knowlege of opening traps. I was a fairly weak player in the 90's and he always managed to get me in an opening trap.
One day I happen to be in earshot of the chess team leader and the player next highest on the team, talking about how crappy the 16 year old was at chess, always just playing for traps and not studying chess seriously.
I was the "backup" player on the team, which was a nice of saying I sucked at chess.
The team was 4 players plus an alternate, so they would have to be short 2 out of 5 players for me to actually play on the team.
Of course everybody played at chess tournaments, but only team members counted for team trophies and prizes.
easy rite
