Related to open problem #1: Which configuration?

Logic Level 1

You can only place two knights, two queens and two kings on a chessboard .

Is there a chessboard configuration where two queens exactly attack two knights and two knights exactly attack two kings?

Rules:

  • Knights cannot attack each other.

  • Queens cannot attack each other.

  • Kings cannot attack each other.

  • The size of the chessboard cannot be greater than 8 × 8 8 \times 8

Is the phrasing ambiguous? The two queens should attack two knights not the kings.

.... two queens exactly attack two knights and two knights exactly attack two kings?

Yes, as I see it the phrasing is ambiguous. I don't see anything in the question that makes a claim about how many kings a queen may attack. It only mentions all queens have to attack 2 knights, and that the queens aren't allowed to attack each other. That's happening in my solution.
