Open tasks for a future Janggi implementation:

  • Elephant move (lame leaper)
  • bikjang (facing kings)
  • Cannon capture rules
  • Moves along the lines of the palace (king, guard, chariot, cannon, soldier)
  • Passing
  • piece counting in bikjang
  • repetition/perpetual handling

Perhaps out of scope:

  • transposition/drop rule in start position

Ideas:

  • handle palace moves as diagonal moves of type SPECIAL, and consider in both movegen and attackers_to
  • treat passing as a king move with from == to, similar to sittuyin promotion
