Chess Logic Puzzle

Three pieces—a rook, a knight, and a bishop—are placed somewhere on a standard chessboard.

You are given the following clues:

1. No piece is attacking any other.
2. The rook and knight are on squares of opposite colors.
3. The knight and bishop are on squares of the same color.
4. The bishop could attack the rook if both pieces shifted one file to the right (keeping their ranks the same).
5. The rook is not on the edge of the board.

Question:
What color square is the bishop on—light or dark?

Answer is no solution. Bishop and rook are on squares of opposite colors. Shifting one file to the right just flips colors of both rook and bishop. Bishop can't attack rook.

There is a solution.

The rook is not on the edge, but the bishop is.

Am I right?

Technically mine works

That is correct!!

But technically doesn't that mean it can be on both?

The Impossible Checkmate

Position description (White to move):

• White pieces: King on g2, Queen on d1, Rooks on a1 and f1, Knight on e5, pawns on a2, c2, f2, g3, h2
• Black pieces: King on g8, Queen on d8, Rook on a8, Bishop on b7, Knight on f6, pawns on a7, b6, c7, f7, g6, h7

Additional information:
White announces “Checkmate in one.”
Black laughs: “Impossible — none of your legal moves give checkmate!”
The arbiter studies the position and responds:“Actually, White is telling the truth.”

Your task is to determine:

Puzzle Question

How can it be White to move and also have a forced checkmate in one when no legal move on the board delivers checkmate?
What fact about the previous move makes the situation possible?

This is the position.

Thank you for doing this.

Using the force

Is it atomic????

Genius. My thoughts exactly

Hint: Think about retrograde analysis — what move must Black have just played?

En passant?

The first thing I remembered was Mercury retrograde

You mean Venus? Venus is retrograde. But that was the first thing I thought of lol
