A Chess question...

Prolly just easier with the picture...

Nevermind, I don't recommend using ChatGPT as an authority on chess. :D Here it kept insisting that it is possible to put a piece between an attacking pawn and the attacked king, and other plainly terrible things, reposting here as it's hilarious:

ChatGPT: If an unsupported pawn moves to a square that attacks the opposing king and puts it in check, the opponent must respond by moving their king out of check, capturing the attacking pawn, or blocking the attack with another piece. If none of these options are available, the game ends in checkmate, and the player with the attacking pawn wins.​

Me: How would they "block the attack with another piece"? A pawn just attacks diagonally one step.

ChatGPT: You are correct that a pawn can only attack diagonally one step, so it may not be immediately apparent how another piece could "block" the pawn's attack on the king. However, there are a few situations in which this could happen:

Interposition: If the opposing king is attacked by a pawn, and a piece of the opponent's is positioned between the king and the pawn's attacking square, that piece can be used to block the attack. This is sometimes referred to as "interposition."

Capture: If the opposing king is attacked by a pawn, and a piece of the opponent's is located on the attacking square, that piece can capture the attacking pawn and remove the threat.

Deflection: In some cases, a piece can be used to deflect the attacking pawn away from the king. For example, if a rook is attacking the pawn, and the pawn is also attacking the king, the opponent could move a piece in such a way that it attacks the rook and forces it to move, breaking the pawn's attack on the king.

Me: Explain how interposition is possible between a pawn and a king.


ChatGPT: When we talk about interposition in chess, we usually mean a piece being positioned between an attacking piece and the target piece that it's trying to capture or attack. In the case of a pawn attacking a king, it's not possible for a piece to be interposed directly between them because pawns can only capture diagonally, and a king cannot be placed on a square adjacent to an opposing pawn.

However, interposition can still be used to block a pawn's attack on a king indirectly. For example, if a bishop is attacking the opposing king, and the pawn is on a square that is adjacent to the king, the opponent could move another piece (e.g., a knight or a bishop) to a square that is between the attacking bishop and the pawn, effectively blocking the bishop's attack on the pawn. Since the pawn is no longer attacking the king, the king is no longer in check.

Another situation where interposition could be used is when a pawn is attacking the king along a diagonal, and there is a piece of the opponent's blocking the way on that diagonal. The blocking piece can be used to interpose between the pawn and the king, effectively blocking the pawn's attack and removing the check.​

Here's a pawn that has the checkmate with black to play. Can't go anywhere.

1k6/PP6/1Q6/8/8/8/8/4K3 b - - 0 1

Agreed, this is how I interpreted it. But I wonder how OP would consider it not possible. Or in what circumstance.
 
I've played a lot of chess and cannot recall ever seeing just a pawn and king combo achieve checkmate without promoting the pawn on the opposing row to Queen.
Me either, I use to go to tournaments with my late mentor. The joy of seeing a old engineer beat a tween prodigy(Sam Severin). Victory for a geezer!
 
I don't think a pawn-King combo can acheive mate without a defending pawn locking the King into the corner.
But I'd love to see it!
