	Introducing the Chancellor - moves like either a Rook or a Knight. 
This piece has been studied (under various names) from 1617 (D. Pietro
Carrera) to 1995 (Ralph Betza).  Betza's variant, called Almost Chess,
simply replaces the Queens in the initial position with Chancellors.

	Here is the shortest possible game of Almost Chess: 
1. Cc3 Nf6  2. Cxc7 mate
Note that some Pawns are undefended at the start of the game - a common
hazard of chess variants. 

	I have prepared some positional bonus tables, given below, for
inclusion in the EVAL.C files of GNU Chess on 8x8 and 10x8 and 10x10
boards.  On the standard 8x8 chessboard I am inclined to rate the
Chancellor at half a Pawn less than the Queen - assigning material
values of 930 and 980 points, respectively.  WARNING: I know a lot more
about mathematics than I do about chess, so this message continues the

	Back to Ralph Betza's Almost Chess.  The simplest way to adjust the
GNU Chess program to play this variant is to redefine the Queen as a
piece moving like either a Rook or a Knight, keeping the standard name
and symbol in the game.  In this case, you could call the table below a
Queen positional bonus table ... pqueen[64].  This approach has the
drawback of not allowing you to try out Betza's suggestion of mixing
the two pieces: Chancellor on d1 and Queen on d8.  Good Luck! (and
please replace (at) with the correct symbol if you wish to Email me)
