# chess on an infinite plane: vickalan vs rychessmaster1

I'll give you White. Rules and board coming up in a few minutes. Sorry I'm late. From here 3 days per move, right? (I usually play a move per day).

@rychessmaster1 (White) vs. @vickalan (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.

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.

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:

Orange brackets identify 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 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)

rychessmaster1 plays White. Good luck!

Nice opening.

The two hawks opening:
1.H(1,-3)...H(1,12)

And the board.

Now the four hawks opening:
2.H(8,-3)...H(8,12)

Ok, the actual board:

3...H(4,9)

Is there any reason we haven't brought castling into infinite yet?

Castling is obviously well-suited for normal chess, but I'm not sure if it would add anything interesting here. First, the rules would have to be defined. The king and rooks start farther away, so it would have to be decided how far each piece travels to castle. And would different castling distances be allowed? So one negative is that the rules become more complicated.

But does it make anything more interesting? It might be interesting to see the king suddenly jump (castle) if it improves his defense. But without the option, the opponent might have more interesting options for harrassing the king. Not sure if one is better than the other.

So on balance, I don't really see castling as being something positive. But it can be tried if anyone wants to. As for me, I would rather keep playing without it (just my preference).

4...H(5,9)

Fair enough, I'll save that discussion for another thread and another time.

And other infinite chess stuff can be discussed here:

(openings)

(general)

5.(4,4)...N(6,6)

6...(7,6)

Not to interrupt, but my thought on castling would that it would have a negligible impact on gameplay. After all, in the first Mortagen matchup, which involved castling, little affect took place.

Also, is this now an official variation of the Four Hawks?

Need to skip today. Bloody nose (from playing outside and throwing the ball) and just wanna go to sleep. Be back tomorrow.

Sorry I didn't notice this yesterday, but that move is illegal. Do you mean B(6,4) or B(7,5)?

np
7.B(7,5)...N(5,4)
