27 Besides, a new piece is introduced: the immobilizer, represented by the letter 'm'
28 in FEN diagrams and PGN games. It is represented by an upside-down rook:

39 | one square in any direction.
40 | All other pieces move like an orthodox queen.

43 When a piece is adjacent to an enemy immobilizer, it cannot move unless
44 the enemy immobilizer is adjacent to a friendly immobilizer or chameleon
45 (cancelling the powers of the opponent's immobilizer).

47 | Note : this corresponds to the "pure rules" described on
48 a(href="http://www.inference.org.uk/mackay/ultima/ultima.html") this page
49 | , which slightly differ from the initial rules.
2316f8b8
BA
50 | The aim is to get rid of the weird suicide rule by weakening the immobilizers lock.
51 | In particular, in the original rules two adjacent immobilizer are stuck forever
52 | until one is captured. Note that it's still the case if all chameleons disappeared.

57 | Easy case first: the king captures as usual, by moving onto an adjacent square
58 | occupied by an enemy piece. But this is the only piece following orthodox rules,
59 | and also the only one which captures by moving onto an occupied square.
60 | All other pieces capture passively: they land on a free square and captured
61 | units are determined by some characteristics of the movement.

66 Note 2: for passive captures, a 'X' is added at the end of the move notation,
67 to indicate that something was taken (replaying the game is necessary to know where).

71p.
72 If at the end of its movement a pawn is horizontally or vertically adjacent to an
73 enemy piece, which itself is next to a friendly piece (in the same direction),
74 the "pinced" unit is removed from the board.

84 Imagine that rook and king are two corners of a rectangle (this works if these
85 two pieces are unaligned).
86 If at the end of a rook move an enemy piece stands in any of the two remaining
87 corners, it is captured.

97 A knight captures exactly as a queen in international draughts game: by jumping
98 over its enemies, as many times as it can/want but always in the same direction.
15c1295a
BA
99 In this respect it is less powerful than a draughts' queen:
100 on the following diagram c8 or f6 cannot be captured.

101 However, the knight does not have to maximize the number of captured units
102 (as is the case in draughts).

136 Besides, chameleon immobilizes immobilizers (but cannot capture them since they
137 do not capture).

140 A chameleon captures the king in the same way the king captures, which means that
141 a chameleon adjacent to a king gives check.

146 Checkmate or stalemate as in standard chess. Note however that checks are more
147 difficult to see, because of the exotic capturing rules. For example, on the
148 following diagram the white king cannot move to the marked squares because then
149 the black pawn could capture by moving next to it.
