Did you know there is actually a chess variant that uses dice?
1 - move a pawn 2 - move a knight 3 - move a bishop 4 - move a rook 5 - move a king 6 - move a queen
If you have no legal moves to make with the designated piece, you simply roll again and move with the new indicated piece.
With these chess dice above, you wouldn't even need to agree that 1 stands for pawn moves
Actually I have never played the variant as described above, maybe the real rules are a little bit different
I am going to use these to see if there is any effect on the ability to imagine two random chess pieces on different squares of the board.
Roll # 1: white....rook on....a1.
Roll # 2: black knight...on...b3.
Hey, the black knight can capture the white rook. Look-out!
...Rolled the one for the white pieces and got bishop on b1. Then I rolled the one for the black pieces and got pawn on h6. Then I made a diagram in order to study the relationships between these two pieces on these two squares. Cool.
How are they related? Well, the white bishop is probably going to want to stop the pawn from traveling down the h-file to promote. I know, I know...the kings are not on the board. I knows, I knows.
Cognition. Randomness.
Roll # 1: white rook b3
Roll # 2: black rook a1
I'm not even sure R vs. R is a draw as you can never exchange them
Roll # 1: white rook b6
Roll # 2: black bishop c7
The bishop is attacking the rook.
