A short note about how the coordinates work would also be helpful, or just highlight the target square, because not everyone knows chess notation by heart. I tried two different interpretations (both wrong) before finally resolving to google for it.

> not everyone knows chess notation by heart.

I am going to agree, and hopefully clarify the point with a slightly different example. While I know how the notation works, I cannot figure out where a particular square is at a glance. This meant a lot of time squinting at the tiny, low contrast labels at the edges of the board. It made the problem a lot harder to solve since my concentration was constantly being disrupted by figuring out where the next destination is, rather than focusing upon the pattern of the knight's moves.

They are written on the board..?

Wow, I totally didn’t see those. Much too small and low-contrast, they are basically invisible on a smartphone.

I'm not seeing the letters. I see the numbers and vaguely knew enough about chess to know which way the numbers go. Honestly, I really only know about the board location designations because of the puzzle under the word scramble in the paper that asked you to accomplish something on the example chess board. The answers to the previous challenge were written (upside down to prevent accidental spoilers) in the standard(?) chess notation.

I did not see those markings at all - nor did I see the label indicating the square to jump to, until quickthrower2's explanation cued me to look for it!

(I see now that the target-square notation is much more prominent if you stretch the window horizontally, but I habitually use portrait-mode windows, where it's very small.)

It asked me to move to e8...but that's a move where the Queen takes Knight. I don't get it.

[aleksandrm]

Look again. The queen doesn't take the knight at E8.

[wyclif]

You're right, but I naturally hesitated to move there because I play chess a lot.
