My 5yo pupil, Magnus, is playing his first chess tournament. Although I missed his first game, @Elder helped me reconstruct this important first win from the few clues I could collect.
Alas, the second round started when I was still reading @Elder useful answer on Puzzling.SE, and I missed the action again! When I reached the playing hall, Magnus and his opponent, a 7yo girl, were already putting the pieces back in their starting places.
Luckily, Magnus' bright smile left me no doubt about the result: he won again. He was Black this time, and the five bars in each column (for White and for Black) on his scoresheet prove that, once again, the game was a very short one.
When I asked him what happened, he told me:
"I took her rook with my knight, hop! I was already so happy to eat a rook, but moreover, after I played it, I noticed that I was attacking her king, and she had no escape... Checkmate, I won again!
-Impressive, congratulations, Magnus! Err... Do you remember what happened before ?
-Hmmm, not quite, the board is so big... At first I was a bit afraid because she is taller than me, and she started with the pawn in front of her king, two squares - I remembered you told me this is a great move to start with, so I thought she must be very strong to find it. But then I just played a few moves, and my horsey ate her rook, and wow, checkmate!"
I could not get any more details about how the game went, so once again I need to ask you to help me and reconstruct what happened.
TL;DR
Find the chess game where White starts with 1.e4 and Black plays 5...NxR#
