   (description "Object: Checkmate the opponent's King by attacking
	   it so it cannot escape.\\
Moves and rules\
Most rules are as in usual chess. We mention the differences only: \\
The chancellor has the combined moves of rook and knight, i.e., each move the chancellor may move either as a rook, or as a knight. (This is similar to the queen, who has the combined moves of rook and bishop.) 
The archbishop has the combined moves of bishop and knight.\
When a player castles, the king always moves three squares towards the rook.\
Pawns can promote to queen, archbishop, chancellor, rook, knight, or bishop, to the owning players choice.")
   (history "The great chess master and world champion Jose Raul Capablanca (1888-1942) proposed this chess variant, after he had gained the world champion title from Lasker. A description of this game can be found in the books of Gollon and Pritchard.")
   (strategy "In the opening, try to develop your pieces more than your pawns.  Always
       protect your King.  Look for ways to exchange lower valued pieces for larger valued
       ones.  Generally, if a Pawn is worth 1 point, then a Bishop or Knight is worth 3,
       a Rook is worth 5 and a Queen worth 9 points. The Archbishop and Chancellor are worth
       something between a Rook and a Queen, with the Chancellor worth almost as much as a Queen.        WARNING: the Pawns at i2 and i9 are undefended!")

   (title "10x8 Chess setup 3 -- Doublemove")
   (description "Object: Capture the opponent's King.\\
Moves and rules\
Most rules are as in usual chess. We mention the differences only: \\
The chancellor has the combined moves of rook and knight, i.e., each move the chancellor may move either as a rook, or as a knight. (This is similar to the queen, who has the combined moves of rook and bishop.) 
The archbishop has the combined moves of bishop and knight.\
When a player castles, the king always moves three squares towards the rook.\
Pawns can promote to queen, archbishop, chancellor, rook, knight, or bishop, to the owning players choice.")
   (strategy "In the opening, try to develop your pieces more than your pawns.  Always
       protect your King.  Look for ways to exchange lower valued pieces for larger valued
       ones.  Generally, if a Pawn is worth 1 point, then a Bishop or Knight is worth 3,
       a Rook is worth 5 and a Queen worth 9 points. The Archbishop and Chancellor are worth
       something between a Rook and a Queen, with the Chancellor worth almost as much as a 
       Queen.")
