To a casual bystander (who at least knows the rules), castling seems a bit arbitrary and so do the other "extras" - en passant et al. What would happen if chess was reduced to purely "normal" piece moves? What happens if pawns lose their initial two square move? Obviously it would reduce the space of potential games by quite a lot but would it reduce chess to draughts/checkers? Shall I pick my own stake to be burned at?

Taking them out would slow the game down, and we've at least a hundred years of the new rules (faster games) being preferred.

  Would you mind pointing me at a canonical source on that please. Chess is way older than a few centuries, so why do the extra rules sidle in and when?

    > Chess is way older than a few centuries, so why do the extra rules sidle in and when? Not exactly what you were asking, but you may be shocked to learn that Chess has had two significant patches very recently - namely clarifying the rules to prevent promoting a pawn to an enemy piece (sometimes causing a smothered mate), and to prevent castling with a pawn promoted to a rook on the 8th rank (annotated humourously as 0-0-0-0-0-0!!). These patches were seemingly implemented in the late 19th century and 1970s respectively, although it's surprisingly hard to find out precisely when.

      Those are obscure. "White goes first" was established in the second half of the 1800s!

        > Those are obscure. Obscure, but also completely to do with how the pieces on the board can actually move, which I bet most people would have suspected that we worked out a few centuries ago. The decision of who goes first doesn't really matter, it's a purely aesthetic choice. Similarly there's a lot of regulatory changes to this day around things better described as "playing conditions". But banning 0-0-0-0-0-0 is fundamentally the same category of change as saying "oh and also the queen can move like a knight now", which seems like an absolutely ridiculous thing to have still been refining in the 1970s.

        There's no way they would have allowed 0-0-0-0-0-0 or "promote to opposite color piece" in a real game if GMs tried it in 1965. It's only ambiguous wording of the rules that was fixed in 1970, and not actually a capability of pieces.

        IRL games don't blindly execute the rules like video game code: in rare cases it's possible for the rules are poorly worded in a way that would allow something stupid, and yet that wouldn't be actually permitted play by any reasonable player or arbiter. It's happened several times in MtG tournament history for example, where some mechanism was so clearly against the intended rules that the judges just didn't allow it even though it would have worked as a strict reading of the rules (nonsense about actions "between turns" and I recall Yawgs Will exiling as a triggered effect both just getting shut down by judges). The two things you mention are solely gags for funny chess puzzles about what is an obvious oversight in some specific written rulesets, not actually something that would have actually been legal play.

  "Half Chess": use half the board, eliminate the pawn rows. Much faster.
