Figured we should give this a try.
Basically, the left side and right side don't exist.
For example:

8 . N B . K B N R 8
7 P P P P P P P P 7
6 . . . . . . . . 6
5 . . . . . . . . 5
4 . . Q B B Q . . 4
3 . . . . . . . . 3
2 P P P P P P P P 2
1 . N B . K B N R 1
A B C D E F G H
WHITEIn normal chess, the Queen can't capture the other one.
In this variant, though...
BLACK

8 . N B . K B N R 8
7 P P P P P P P P 7
6 . . . . . . . . 6
5 . . . . . . . . 5
4 < < Q B B Q < < 4
3 . . . . . . . . 3
2 P P P P P P P P 2
1 . N B . K B N R 1
A B C D E F G H
WHITEThe borders don't exist on the left or right side.
If the north and south sides were gone, it'd be checkmate at the start of the game

This test game is to see whether it will work.
In most chess games, one person plays against another.
However, for this test, I'll let all members control Black.
For example, Dr. Egregious can control Black's movement in the first turn, Shane can control the second turn of Black, Kushagra controls Black's third turn, and so on.
Also, if Dr. Egregious and KarjamP both post their move before the movement is made, Dr. Egregious' move is made and KarjamP's cancelled.
If Shane and Dr. Time both post their move before the movement is made, Shane's move is made and Dr. Time's move is cancelled.
Something like that.
First one to post has that movement made, in simple terms (I hope).
