Line 3: initial setup of black pieces on back rank\r
Line 4-18: Description of piece types that can occur in the variant\r
\r
-There can be upto 15 piece types per variant, numbered 1 to 15.
-Numbers 1 and 2 are considered Pawns for white and black, respectively,
-and the 2nd and 7th rank of the opening setup will be filled with them.
-These pieces will automatically promote to piece number 7 when they
-reach last rank. So in normal Chess, piece 7 should be programmed as Queen.
-
-Castling can be done only with the original corner piece as specified
-by line 2 and 3. Any royal piece can in principle castle. (Subject to
-the normal restrictions on castling, i.e. not passing through check etc.)
-If you don't want that, remove the castling moves from the King description.
-If the castling initiator does not start in a central file, the results are

individual bits specify the various options\r

-The piece indicator character is used to set up positions, and for the
-promotion choice as 5th character of an input move. (Fairy-Max itself
-always promotes to "Queen", i.e. the 7th piece of the list.)
-If more pieces use the same letter, the first one is used for white,
-and the last one for black. If more than two have the same name, the
-others cannot be indicated at all, but they could still occur in the
-initial setup (where you specify them by number, not letter).
-
-NOTE: piece value 181 for piece 7 is reserved for Makruk, and enables
-promotion on the 6th rank. Do not use it in other variants.

+Pieces with negative values are considered royal. If one side has more than\r
+one royal piece of the same type, he loses if the _last_ one is captured,\r
+with the special rule that he is not allowed to leave more than one of\r
+them under attack. This means the 'spare' royal pieces can be sacrificed,\r
+and the exchange value assumed for them will be the absolute value of what\r
