Experimental large multi-move variant.
By: Martin0 Date: April 30, 2018, 10:56 am
---------------------------------------------------------
This variant is intended as a large board multi-move variant to
test its concept if it can be made and still keep the
traditional feel of chess intact without affecting the length of
the game and strategy of the game too much. Only slightly
modified versions of the traditional pieces are used, no new
pieces. If this variant proves to be playable, then chances are
balanced large multi-move variants with new pieces can be made
as well.
Board setup:

Movement:
All pieces can jump over up to 2 pieces, except knights which
can jump over any number of pieces.
Pawns can move up to 6 squares forward when they are on the 4th,
5th or 6th rank. Otherwise pawns can move up to 3 spaces
forward.
Pawns captures by moving up to 3 squares diagonally forward.
Pawns promote on the 22th, 23rd and 24th rank.
Pawns can only be captured en passant when they move 4 or more
squares forward.
Knights moves 6 squares straight and 3 to the side.
Kings can move up to 3 squares orthogonal or diagonal.
Queenside castling is made by the king moving 6 squares to the
left and moving any number of rooks on the left side (that has
not moved) 9 squares to the right.
Kingside castling is made by moving the king 6 squares to the
right and moving any number of rooks on the right side (that has
not moved) 6 squares to the left.
When castling, all squares the rooks and king is moving over
must be empty (not counting rooks that are moved during the same
turn).
Rooks, bishops and queens move as in traditional chess (any
number of squares orthogonal and/or diagonal).
Army movement is a special multi-move that can be made by pieces
standing in a 3x3 area on the board and all pieces need to be of
the same piece type. Any number of pieces (above 0) can
participate in the army movement. In an army movement, the
pieces moving together must move the same amount of squares in
the same direction (so the move needs to be legal for each piece
participating). If a capture is made during army movement, then
a piece is allowed to move over an enemy piece as long as the
piece it jumped over was captured during the army movement
(without that jump counting towards the jump over max 2
pieces/move).
If several pawns promote during the same turn in army movement,
then all pawns needs to promote to the same piece.
Example:
1.A(n5)-n11 A(n20)-n14

2.A(Nt2)-q8 A(Ne22)-h17
3.A(k5)-k11

Black can capture up to 9 pieces with army movement with either
his pawns or knights if he wants to. Or with fewer than all 9
pieces is also an option. Black chooses to capture with all 9 of
them.
3...A(n14)xk11 4.A(Nq8)xk11

Black wants to develop his bishops with army movement and attack
whites knights. However, since pieces can only jump over a
maximum of 2 pieces and one of them would need to jump over 2
pawns and 2 knights, only 8 bishops can participate.
4...A(Bq23,q24, r24, p23,r23,p22,q22,r22)-h14

5.A(Bh2)-n8
[img]

Now 3 of blacks bishops can capture whites bishops since they
only jump over 2 pieces.
5...A(g13,g14,h13)xm7

6.A(p4,p5,q4)xm7
[img]

6...A(Qk23)-q17
7.A(n11)-n12
[img]
HTML https://i.imgur.com/io9utlV.png?1[/img]
Whites pawns are threatening to capture 3 queens
7...A(Qq17)xq5#
[img]
HTML https://i.imgur.com/jsD9W2v.png?1[/img]
3 black queens are threatening to capture whites king. White can
not capture all 3 or make a different move to escape the check,
so it is a checkmate.
I think a well played game can be much longer, but this is just
a miniature to illustrate how it can work.

Interesting try. I don't recall seeing this design, a direct
expansion of each piece and board square into 9*, although I've
run across somewhat similar ideas. Is it playable online? I'd
help playtest it.
As far as how it will play, let me first steal a line from my
recent comment to HG in another thread. "... the 'piece' now has
"hit points", and can survive losing some units. It has general
attack and defense abilities that are based on the number of
units in the piece and how the units move, modified by the
*exact*placement of all units involved..." *except the king. You
use a 'crippled king' strategy here. Any reason why, except you
didn't want to play 'capture the king'?
You use rigid 'pieces' that can partly interpenetrate to make up
for their rigidity. But, as your example game shows, you lose
parts of 'pieces'. That changes the strategy of the game
somewhat from standard chess, because as the game wears on,
players tend to use the pieces with the most remaining units -
this observation based on experience with chesimals, which are
essentially a flexible version of your 3x3 square piece.
Further differences from standard western chess include
GESS-like creation of pawns, and 'color-changing' bishops, or at
least bishop units changing from one 'army' to the other, as
apparently any 3x3 set of board squares can define an army. That
leads to an even greater fragmentation of 'pieces'/armies into
smaller clumps of similar units. The armies become disorganized.
In fact, attacking to disorganize your opponent's armies becomes
a viable strategy if you can develop one or more ways to do
that.
I suppose you could restrict the 3x3 squares to the 64 defined
by the initial set-up of 'back rank pieces' but this would
remove some/much of the fun and strategy. How about you have a
"rally" command that calls back scattered units of one type to
re-form near the king? Maybe call back all units of 1 type in a
player-designated 7x7 square, for example?
Anyway, is there a way to play this online?

I just made this variant in less than a day, so there is no way
to play this variant online. We could do a correspondence type
game where I update the diagrams though.
The reason I made the king alone was because I didn't want
multiple royal pieces. I could give him non-royal guards which
starts around the king. The guards would move and capture as a
king (including castling) and can participate in army movement
with the king, but the guards would not be royal. That would
make the king stronger and not exposed to checkmates by queens,
such as the example game.
I think trying to keep your pieces organized can be an
interesting aspect of strategy. If your pieces are disorganized,
then you can try to organize them by moving them next to each
other. I don't think a rally command to make this easier is
necessary. Armies start with the same size at the start, so a
lot of different armies will probably be moved and trying to not
make them smaller is an interesting aspect. Pieces left alone
might not move for a long time, but their still there and might
be relevant in the future.
I will probably also add that castling can be legal with the
king or rook moving over up to 2 pieces to make it consistent
with other movements.
Do you want to try to play this variant with me correspondence
style with guards (indicated by upside down kings below)? Or is
a lonely king better? Any other rule that should be revised
first?

This reminds me of a concept I came up with called Cantellated
Chess where each edge and corner of the chess board was replaced
by a square.

Do you mean that the board was just 10x10 squares? How would
that work? Please do explain! ;D

I suggest variant, where group of stones (all players's stones
in square 3x3) move according to central stone.

Well imagine a chessboard with all the normal pieces and normal
moves. Now stretch out the board so that the corners and edges
also turn into squares. Now you can block knights and stuff like
that.
