Very very creative and interestering
Formation chess

Do you think this is played best with only knights and one king, or are other chess pieces mixed in? Maybe we can try it on an "Infinite Plane" chessboard.
I just can't think if the knights should be about half of the total non-pawn pieces (like 8 knights, 6 other non-pawn pieces, and 14 pawns in front of them) per side, or should there be even more knights, for most intriguing play.


A mix with other pieces would be great, but there should be just enough knights in order to have a reasonable chance that this extra feature will acually play a role in the game. 8 knights would be the minimum.
I doubt about the 1x2 formations going as Chu Shogi movers, because it could become too overwhelming. It needs to be tested.

OK, I'll try to create some initial formation of pieces. I think it's OK to have plenty of knights because they aren't too powerful, and when you line them up next to each other they don't attack redundant squares. When they do start to create a formation, it may not be wasted moves while they are forming a 2x2 block. I'll try to post here again in a day or two.
(I'd like to get to it even sooner, but other games are keeping me busy)




This is great! And let's indeed try without the 2x1 and 1x2 formation option. Pls let me know when you can manage to start this game.

1 queen
2 rooks
2 guards
14 knights
20 pawns


A red bracket indicates the a1 (1,1) square.
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)


That's the first time I've seen a piece go backwards in an opening move. I was wondering if there's new unusual openings, like forming a tight defensive cluster (and waiting for your opponent to make first attack). But I better not say more.
1...N(5,6)



Formation chess is played on a large board, 24x24 to start with.
Both players have lots of FIDE chess knights and one king. The aim is to capture the opponents king.
If some knights are in some particular formation, they get different movement abilities as a group. Three formations exist with the following movement:
2x2 formation can move like a queen
1x2 formation can move like a Chu Shogi side mover (horizontally as a rook and vertically one step)(TEMPORARILY ABANDONED)
2x1 formation can move like a Chu Shogi vertical mover (horizontally one step and vertically as a rook)(TEMPORARILY ABANDONED)
