Variant Description - Chess on an Infinite Plane
By: chilipepper Date: January 13, 2018, 2:03 pm
---------------------------------------------------------
Here is the rule-set for "Chess on an Infinite Plane" (one type
of an infinite chess game):
(The game description is also specified at
HTML http://www.chessvariants.com/invention/chess-on-an-infinite-plane).
The Pieces:
Black and White each have the following pieces (quantity and
name):
1 king
1 queen
2 chancellors
2 rooks
2 bishops
2 knights
2 guards
2 hawks
24 pawns
All pieces move as in classical chess, with the "extra" three
pieces moving as follows:
Chancellor (C) - Moves and captures as rook + knight.
[attachimg=1]
Hawk (H) - Leaps exactly 2 or 3 squares in any orthogonal or
diagonal direction. The leaping move means it can jump over
other pieces.
[attachimg=2]
Guard (G) - Moves and captures the same as a king but is not
affected by check.
[attachimg=3]
Pawns play the same and promote at the same rank as in classical
chess. White pawns promote at rank 8, and black pawns promote at
rank 1. Pawns can promote to chancellor, hawk, or guard in
addition to queen, rook, bishop, or knight. Pawns may capture
and be captured en passant with the same rules as in classical
chess.
Board Setup:
[attachimg=4]
Orange brackets indicate the four "classical" corner squares
(1,1), (1,8), (8,1), and (8,8).
There is no castling.
There is no fifty-move rule. Draws can only occur from
stalemate, threefold repetition, agreement, or a proven case of
insufficient material to force checkmate.
All other rules are the same as in classical chess.
Move Notation:
Numeric coordinates are used to identify piece locations as
(file#, rank#). Parenthesis are used around each coordinate.
Three examples of a move notation:
1) A rook moving from (8,4) to (1,4):
R(8,4)-(1,4) or R(1,4)
2) A rook moving from (1,4) and capturing a piece on (0,4):
R(1,4)x(0,4) or Rx(0,4)
3) A pawn advancing from (-1,7) to (-1,6):
(-1,7)-(-1,6) or (-1,6)
Feel free to leave comments, ideas, theory, strategy, game
results, etc. on this thread. :)

IDK seems like games like this would be a sluggish bear.
1. for example shogi is really slow until you start capturing
pieces and dropping them.
2. even a board game like feudal you're able to move all the
pieces you want on one turn and still it's slow.
apologies for not knowing how to make a link will just paste
them

The game can also quickly develop a deadly dynamic when stronger
pieces are in play. Here's an example with a checkmate after 13
moves.

Thanks elephant and McGoohan for your comments. The study of
game length for any variant (and chess itself) is very
interesting to me.
I've seen both very short and long games. I'm actually surprised
some games haven't been longer - I think theoretically a game
between two expert players (and without strong pieces added) can
be much longer than normal chess. If the center armies don't
lead to an advantage for one side, then the hawks and pawns in
the rear formations will come into play, with the pawns
requiring a long journey to possible promotion.
I'm not sure of the longest game. One game was played with the
huygens (a piece which jumps prime numbers of squares). This
game was 94 moves (notation below). If I hear about any shorter
or longer games I'll bring information here. :)
