\r
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
+This means any 'spare' royal pieces can be sacrificed, and the exchange\r
+value assumed for them will be the absolute value of what you defined.\r
+With a value -1, however, loss of the first piece of that type loses the game.\r
For royal piece types larger than 7 there is the special rule that it is not\r
-allowed to leave more than one of them under attack. This means the 'spare'\r
-royal pieces can be sacrificed, and the exchange value assumed for them will\r
-be the absolute value of what you define for them.\r
+allowed to leave more than one of them under attack ('duple check').\r

NOTE: piece value 181 for piece 7 is reserved for Makruk, and enables\r
promotion on the 6th rank. Do not use it in other variants.\r
