This thread is for a game of "Chess on an Infinite Plane" between cobra91 and vickalan.
 
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.

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

Guard (G) - Moves and captures the same as a king but is not affected by check. Other information on the guard can be found (here). (not particular to this game)

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:
phpYeLjQp.png
A 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.
 
The Chessboard:
1. Board for OTB Play:
A playing area should be setup with at least 24 ranks and 20 files. Ensure provisions are available to expand the board if play requires. If this becomes inconvenient due to far-away pieces, a display board is used to indicate the location of remote pieces. If there is interesting play in small but remote areas, other playing areas can be labeled and used separatelly from the main board.
 
2. Diagram for Online Play:
A chess diagram is used to indicate the position of pieces either after each move by white, or each move by black. The diagram should include 24 ranks and 20 files. If any pieces are moved outside of this area, the diagram is expanded or notes are shared to indicate the location of far-away pieces.  If there is interesting play in small but remote areas, other diagrams can be used to show piece positions separatelly from the main diagram.
 
Move Notation:
Numeric coordinates are used to identify piece locations as (file#, rank#). The "a1" square is (1,1) and is marked on the chess diagram with a small red bracket. Increasing files are to the right, and increasing ranks are toward the back.
 
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)

It's not easy to choose an opening move here, as there are endless possibilities... literally. Laughing  For instance, Q(4,1)-(4,0) or Q(4,1)-(4,-1) or Q(4,1)-(4,-2) or... Undecided

But I'll go with: 1. (7,2)-(7,3)

vickalan

I would be very surprised if trying to play a piece from behind could be a good opening, but maybe something for an adventurous player to try in the future?

If it's OK with you, I'll post only the destination square of pieces, except when the long notation is needed to remove an ambiguity. So your move and my reply are:

1.(7,3)...(5,5)

Alright; I suppose it's fine to use the same piece symbol for "Guard" and "Grasshopper", since all ambiguity is removed by the lack of grasshoppers in Chess on an Infinite Plane and the absence of guards from Grasshopper Chess.

My move is:  2. (2,3)

vickalan
That would be interesting - a grasshopper in this game, or a guard in grasshopper chess. Right now the colors and styles are all different, but migrations are possible!

Btw, If you ever need to make a move outside the displayed image just announce it.  I can pan the view, or scale it out if needed (unless pieces go really far). I'm not saying any piece moving far is good strategy or not - just that borders aren't a limitation in this game.happy.png
I'll play:
2...N(3,6)

Continuing:  3. G(2,2)

I like your idea of posting moves in bold:

4...(4,5)

cobra91

Thanks, but the idea is something I merely picked up elsewhere. Posting moves in bold is commonplace in most chess variant forums.

5. (11,2)

vickalan

5...B(6,5)

  6. R(14,1)

6...N(5,4)

I never sign on this late, but it suddenly occurred to me that I'd forgotten to move in these games earlier today:  7. C(12,1)

vickalan

If you ever need to skip a day don't worry. I'm usually in a few games, so I always have at least a few games to reply to. For this game, It's not clear how a guard compares to a knight in value (they both attack 8 squares), but I'll play this:

7...Nx(2,2)

phpC0aOuq.png

cobra91

That should be "7...Nx(3,3)", not "7...Nx(2,2)". I'm actually a bit surprised you didn't take on (6,2); that was a sharp, aggressive option that ought to have been closely examined.

In any case:  8. (4,2)x(3,3)

vickalan

Thanks for noticing my incorrect notation. Capturing the pawn at (6,2)? Your king would have just captured my knight in return I assume. I guess you're saying that would be aggressive because it leaves your king more exposed (at the expense of losing a knight)? Not sure if that's dubious or sharp! I'll play:

8...B(5,7)

9. (9,3)

vickalan

9...(8,5)

If you're going to show the captured pieces as well (which I personally don't think is necessary), it might look a bit less bizarre with the [captured] Black pieces below the board and the [captured] White pieces above the board. The "backwards" display you've chosen seems a little... well, bizarre! Laughing

Nevertheless, on with the game:  10. (-2,2)
