To develop a scan for the Knight I made some pictures which I didn't want to deny you.
It is remarkable that every square of the same color can be reached within two moves (except for 5 squares on the diagonals) when the knight is in the center.
Now it becomes clear why a knight on the rim is dim.
Last friday I had an easy win at the club against 1715.
He played the Cunningham variation at my King's Gambit.
(1.e4 e5 2. f4 ef4: 3. Nf3 Be7 4. Bc4 Bh4+)
However theory clearly states that this check isn't good when whites King can go to f1, everybody plays it.
But even with everything going smooth, I missed a Knightfork at King and Queen against me.
It was pure luck I good parry it. I hope a Knightscan can prevent such oversights in the future.
