HOPPERS\r
GrassHopper:\r
8 hop over non-empty square (normally occupied squares terminate a move)\r
Bits set in the forelast digits TOGGLE the corresponding bits in the last\r
digit. For hoppers when they hop over something, for the other pieces after\r
-every step (so for normal pieces, better not set those bits!).\r
+one to four steps (so for normal pieces, better not set those bits!).\r
\r
The digit before that indicates some special things; a 1 indicates the \r
board should be treated as a cylinder, pieces crossing the right edge \r
C must hop immediately\r
\r
For example, if the initial step vector equals 1, and the descriptor\r
-is 11003, the piece is an alternator (as no hop bit is set), and alternates\r
+is 11003, the piece is a bent one (as no hop bit is set), and switches\r
the mode from 3 to 3 (as the toggle digit is 0), i.e. all steps are moves\r
that can both capture and non-capture, and only captures terminate the ray.\r
-The step vector is toggled by 11, though, and thus alternates between 1\r
-and 10 (hex) = 16. So the piece zig-zags over the board, right, forward, right,\r
-forward, etc. Had the move attributes been 11032, captures would only\r
-be allowed on the odd steps (after moving right), while the even steps could\r
-only be non-captures (both the 1 and 2 bit are toggled). With 11030 the\r
-odd steps can only be skipped (if empty), and the even steps can both capture\r
-and non-capture, meaning the piece moves like a Bishop that can be blocked\r
-by a piece just next to the diagonal.\r
+The step vector is toggled by 11, though, and thus switches from 1\r
+to 10 (hex) = 16. So the piece turns a 90-degree corner, from right to\r
+forward. Had the move attributes been 11032, captures would only be\r
+allowed before the bend (after moving right), while thereafter it can\r
+only non-capture (both the 1 and 2 bit are toggled). With 11030 the\r
+first step can only be skipped (if empty), and thereafter it can both capture\r
+and non-capture.\r
\r
If the first step is a slider, a second step is made (if the square was\r
empty), but if the mode toggles to leaper, the move stops there (e.g. Horse).\r
