Win a chess game in 4 moves

I actually found out about this trick when one of the other chess team members used it on me. I call it the "4-hitter-quitter". You can preform it by following these steps:

If you are black:

• move the pawn in front of u'r king up one space(E7-E6)
• then move the king side bishop to C5
• move ur queen from D8 to F6
• then move ur queen from F6 to F2

   if done correctly, it should be checkmate.

If you are white:

• move the pawn in front of the king up one space(D2-D3)
• then move ur king side bishop to C4
• move ur queen to F3
• then move ur queen to F7

If done correctly it should be checkmate.
