Cambridge is being played, in which case the Immobilizer itself must first be immobilized. When an Immobilizer comes into contact with an enemy Chameleon or Immobilizer, the two pieces freeze each other, after which neither can move unless the other is captured. In the version played at Cambridge, the power of an enemy Immobilizer to arrest a friendly piece's movement is defeated when another friendly Immobilizer or Chameleon is brought up to it, effectively cancelling out each other's power to arrest movement. Some versions of Baroque allow an immobilized piece to commit suicide, i.e. be removed from the board, in lieu of the regular move of that player. There may be strategic reasons to open a line. For example, after the above diagrammed move, the black Leaper on c5 may wish to commit suicide, so that the other Leaper can capture the white Immobilizer by jumping over it on the fifth rank. White cannot hinder this plan, because the Immobilizer is itself immobilized by the black Chameleon. Chameleon/Imitator On the adjacent diagram, the white Chameleon moves Xg6-e6-c6, capturing all seven black pieces except the king in one move and delivering check. It captures the black withdrawer by moving away from it. It captures the black long-leapers by jumping over them. It captures three black pawns by surrounding them. (A chameleon can only capture pawns on a horizontal move or vertical move, not on a diagonal move.) It captures the black coordinator by rank/file coordination with the white king. It delivers check by moving adjacent to the black king. In the Cambridge rules, this capture is not possible. The move is legal, but it captures only the two leapers, because the move is not a legal move for any of the other target pieces. In the absence of the two black leapers, the same move would capture the other five pieces. Variants Maxima Baroque played on a somewhat larger board that is mostly rectangular but for a couple extra squares that are outside the board, located at d0 and e0 just behind the king and queen's squares. A matching pair of squares are also on the other side of the board, just beyond the black king and queen (d9 and e9). Although one objective of the game is to capture the king, an alternative objective allows depositing a piece in the pair of squares on the other side of the board.
