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

+A royal value of -2 is currently used as a kludge to enable an alternative\r
+winning condition, namely when the royal piece reaches (and survives in)\r
+one of the four central squares.\r
+\r
+NOTE: Any piece value that (in decimal notation) ends in '3' will not be \r
+accepted as promotion choice. (And neither will be absolute royalty,\r
+i.e. piece value -1).\r
