Knight to d5. Fork the king and queen (youre welcome)
Middle eastern conflict on a chess board.
I've often wondered if it's always possible to tell whether any arbitrary boardstate is possible, and I came up with a few easy ways to tell how the board can't be legal without verifying that no set of moves can lead to it. Can you spot every illegality?
- White has pawns on the first rank (a1 & b1).
- White has an unpromoted pawn on the eighth rank (h8).
- Black has an unpromoted pawn on the first rank (h1).
- White has three bishops (c1, f1, & d4) while no pawns have promoted.
- Black has two dark-squared bishops (h4 & f8) while no pawns have promoted.
- The black and white kings are touching each other.
- The black king is being attacked but it's white to play.
Both kings cannot be in check, if it's whites turn then black must have made an illegal turn to not avoid check on their last turn.
The white pawn has advanced across the border but hasn't been promoted. A second white pawn moved backwards. Black has a pawn not promoted.
I guess technically white could have promoted a different pawn to be a third bishop, but white is not missing a pawn.
White king and queen could not have moved if the bishops and pawns hadn't (or the pawns would have had to walk backwards)...
The ones I have: touching kings (and so many checks on the black king even though it's not his move), pawns on the first/last rank, 3 bishops even though no pawns have left the board
Edit: the h pawns passed each other
I see two pawns on the last rank but not promoted, black has same coloured bishops
Spoiler
King capture is possible for both players, they both have two bishops on black yet no pawn missing, the edge pawns are in impossible positions and the queens and kings are developed despite the pawns and bishops still in their place. Did I miss something? I can't see anything wrong with the knights or rooks.
I couldn't think of any way to have a knight in an impossible position. I do have one impossible rook, because I updated the link after you left this comment
I'm no expert, but the fact black is in check from the previous move means it can't be whites turn. And it looks like check mate
ChatGPT's games be like
The more you look, the more impossibilities that are found! I'm going to be sick...
Qxb4 h1=KThis position looks like a fever dream
The time waves are getting worse. We used to be playing checkers. Obviously i blame the black science ministry.
