Let me try a more thoughough analysis:<p> Kings and Pawns neither gain nor give relay powers and neither lose nor take anti-relay powers. Therefor a 'piece' in the following analyis is an non-King, non-Pawn piece.<p> 1. There is a set of move types defined for the game. Purely for discussion, let's assume that we are dealing with an FIDE-like variant and the move types are Rook, Bishop, and Knight.<p> 2. A piece has <i>intrinsic</i> moves: these are the move types which the piece is allowed to make, ignoring any relay effects. (The Rook's instinsic move is the Rook move; the Queen's intrinsic moves are the Rook and Bishop moves.)<p> 3. A piece has <i>extrinsic</i> moves: these are the move types defined for the game that the piece does not have, ignoring any relay effects. (The Rook's extrinsic moves are the Bishop and Knight moves; the Queen's extrinsic move is the Knight move.)<p> 4. A effect which causes a piece to temporarily gain the ability to make an extrinsic move is a <i>relay</i>. An effect which causes a piece to temporarily lose th ability to make an intrinsic move is an <i>anti-relay</i>.<p> 5. Relay and anti-relay effects are non-transitive: an effect from piece A to piece B does not alter the effect from piece B to piece C.<p> 6. An extrinic move gained by a relay is not removed by a concurrent anti-relay. An instrinsic move removed by an anti-realy is not restored by a concurrent relay.<p> 7. A piece <i>observes</i> another piece if it has an intrinsic move to the other piece's square. Relays, anti-relays, and check are disregarded--only the line of sight matters. (A Rook on c3 sees a Knight on c6 if c4 and c5 are empty, whether or not the Rook could actually make the move.)<p> 8. The piece which gains or loses movement abilities is the target, the piece which causes the gain or loss of movement abitiities is the source.<p> 9. If the observer is the source, this is a <i>direct</i> effect. If the observer is the target, this is an <i>indirect</i> effect.<p> 10. An effect is intrinsic if the movement abitity added to or taken away from the target is an intrinsic move of the source; an efect is extreinsic if the movement abilty added or taken away is extrinsic to the source.<p> 11. An effect is <i>friendly</i> if it only applies to targets belonging to the same army as the source, <i>enemy</i> if it only applies to targets in the other army, and <i>bilateral</i> if it applies to targets of both sides equally.<p> 12. An effect can be fully specified by in order:<br> a. direct or indirect (direct assumed if not stated)<br> b. instinsic or extrinsic (instinsic assumed if not stated)<br> c. friendly, enemy, or bilateral (friendly assumed for relays, enemy assumed for anti-relays)<br> d. relay or anti-relay<p> So for example the game I mentioned earlier is Indirect Extrinsic Anti-Relay Grand Chess. This is a variant of Grand Chess where a piece which sees an enemy piece loses any intinsic movement abilities it has that the enemy piece does not have.<p> I am considering working up a ZRF for Relay/Indirect Extrinsic Anti-relay Tutti-Fruiti chess.
