Bug report

Current behavior:

The lichess Antichess engine considers castling (0-0-0) as a legal move. Expected behavior: It shouldn't consider castling as a move since it isn't possible

It shouldn't consider castling as a legal move Steps to reproduce:

  1. You open lichess app

  2. You open analysis

  3. You select the variant anti chess

  4. You enable computer-analysis and set analysis lines and cores to MAX (should also work otherwise)

  5. You make these moves: 1.e3 c5 2.Ba6 Nxa6 3.b4 cxb4 4.d3 Rb8 5.Qe2 Qc7 6.Nd2 Qxh2 7.Rxh2 Nc7 8.Rxh7 Rxh7 9.Ba3 bxa3

  6. Now see: the engine says one of the best moves is 0-0-0 which however isn't possible to do.
