Mate in two

Nice one!

Is this from a real game?

I don't know why, but it seems to me so much more appealing if I know it is from a real game.

Or, "Mate in two" is a common type of puzzle - everybody knows, usually they are not from real games?

I am relatively new to chess, forgive my niavety.

1. Nd6

1... if c or e pawn captures or advances, 2.Ba5# or 2.Bg5# respectively. if Na6 or Nc6, then 2. Nf7#

the first time i did a puzzle without it moving! yay!

Correct answers!

My intention was to have a discussion rather than people just checking the solution.

And Garymossu, this is not from a real game. I had the idea of a puzzle with few pieces and where the only correct first move would be to place a piece where it could be taken in several different ways.

Thanks for taking the time to solve it!
