Different 4 move checkmates

i already have that,dnleary.

4 move checkmates are very unreasonable, except maybe the first one, or grifkid52's on a beginer.

why did I actually enter this thread?!

The last one is a TWO move lose, not four, known as the Fool's mate, and as far as the others go, the loser would have to be rated a lot lower than 1200, even if the winner did have a 5000000000000 rating.

ok

im gonna break your rule and put in a mate in 6 i did once 

you do realise the opponent is not dumb? even though your opponent doesn't know these 4 move checkmates, it is still obvious.

Obviously their opponenet is a 2 year old... who would make such dumb moves except those with -2567 ratings?

What is this 4-move checkmate called, I'm genuinely curious because I did this once in game.

Bongcloud mate in 3 moves :

I actually witnessed an 1800 fool lose to a 2000 almost 20 years ago with a 4 move mate in USCF over the board game - No joke!
