This thread is a game of "Chess on an Infinite Plane" between hitthepin (White) and PixelByPixel (Black)Rules:

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.

null

Hawk (H) - Leaps exactly 2 or 3 squares in any orthogonal or diagonal direction. The leaping move means it can jump over other pieces.

null

Guard (G) - Moves and captures the same as a king but is not affected by check.

null

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:
null
red bracket indicates the a1 (1,1) square.

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)

hitthepin plays White. Good luck to both players!happy.png

Oh god... that would be even more infinite and complicated than it already is ES.

😝(Pieces that move very far are shown schematically, so distance to other squares is not to scale)

I will wait for the board.

PixelByPixel: I think you had some of your coordinates reversed. I applied C(13,7)-(13,0) instead of C(7,13)-(0,13). Always remember to specify (file first, rank second). If there's a typo, and it's legal, it could be played as a blunder. Moves applied:
4.(4,4)...C(13,7)-(13,0)
5.C(0,0)...C(13,0)-(13,1)

Great game so far! A little bad news: I'll be travelling and very busy on January 15, so there may be little or no board updates on this day. Or I'll do late in the day. Thanks for your patience.happy.png
