It’s already both happened to me that I didn’t notice I couldn’t move a piece without exposing the king or that I won by accident. Had the game not announced this, I wouldn’t have known.

And perhaps the opponent might not notice my mistake either. Or it could just be a strategic high-risk scenario, rather than a mistake.

    Technically, chess ends one turn before the king is taken. “Checkmate” basically means, “I can capture your king next turn of I want to and there’s no way you can avoid it.”

    You’re not allowed to put your own king in check because, if this were allowed, stalemate wouldn’t be possible; the game would always end with the loser moving their king into check and the winner taking it. The rule allows the player of a losing game to still play for a draw, as opposed to simply resigning.

      Can you explain how stalemates would be impossible if you could self-check? Functionally I don’t see how that’s any different from resigning.

      You could still stalemate by avoiding check and causing threefold repetition.

        If you self-check, your opponents next move is always to take the king and win. Check means ‘if it’s my turn I can capture your king’.

          How is that different from resigning?

          The player can still draw by refusing to self check, right?

            If you refuse to make a move, you resign, you lose.

            If you are unable to make a move, it’s a stalemate, you do not lose.

            It just gives you an extra chance to avoid a total loss by having your opponent make a mistake.

              Got it.

              A game that would normally stalemate because the only move is self check becomes a loss because you have a self check available.

    Sounds like maybe you need to practice more.

    Why, besides supporting your inability to properly apply the rules of chess?

      I mean I absolutely suck at chess (lack of working memory), and it’s clear to me that you are correct.

    You and your friends can set any rules for any games you play, as long as you agree to the rules together. Sometimes it’s fun to try and change the rules.
