European Chess with an obligation, which is not standard in the rules for real-people, tabletop play, to avoid check when possible.
Check must be avoided on the move even if using a special ability after the move (for example, Spain placing a pawn next to the king, Belgium calling in a treaty obligation, the Dutch swapping identities, or Atlantis sinking a square) would prevent the king from being captured.
These are simple illustrations rather than strong opponents.
