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.


  1. Excellent work, gives folks a whole different understanding of piece traffic patterns. I had never thought of color coding a chess board before.

    I did however do something similar to a guitar fret board back when I was trying to establish a reference point in my mind how the scales were connected. (20 years ago) I had long forgotten about it until I saw your chess board.

    Great job!!
    Keep those ideas flowing.

  2. Very nice work. When doing a defensive Knight scan, the 4 diagonal Knight shadow squares (2 squares diagonal distance) are most important. It takes a Knight 4 moves to reach these squares. A Knight scan is also a Queen shadow scan, which may be important in escaping a mate.

  3. Just saw that you marked the Knight shadow square with a 3, must be a typo.

  4. Great. This can be put in words. Q: What squares can be reached by a Knight in two moves? A: All squares the same color of the Knight within a radius of 4, except shadow squares (shown in green). Such things may help to get tactical shots quicker.

  5. Super!
    In endgames you can allways keep your king safe for your opponent's knight.
    It is good for me to train this.
