Chess geometry is not the same as physical geometry. See, e.g., https://en.wikipedia.org/wiki/R%C3%A9ti_endgame_study https://en.wikipedia.org/wiki/R%C3%A9ti_en

- KK7NIL 11mo agoIndeed, it's not even the same between pieces! Kings have Chebysev geometry while Rooks have taxicab geometry: https://en.wikipedia.org/wiki/Taxicab_geometry#See_also https://en.wikipedia.org/wiki/Taxicab_geometry#See_also It's left as an exercise for the reader to figure out the geometry of the remaining pieces.
- daynthelife 11mo agoRooks don't have taxicab geometry. Their metric space is compact even on an infinite board. I think you're thinking of the wazir: https://en.wikipedia.org/wiki/Wazir_(chess) https://en.wikipedia.org/wiki/Wazir_(chess)
