good first puzzle

 yup

There are two possible correct moves on move 3. Either rook can capture the knight. Other than that, it's a nice puzzle.

Thank you. I'm glad that you enjoyed it! ;)

It was a bit confusing, as you flipped the board around, I didn't know it was Black to checkmate, or in how many moves. Try to include those things. White to move mate in one:

it is written (Black to move). take your glasses, come again n try to make good puzzles ;)

 How the heck did white get 3 knights?!!
