Majority Chess

My son is too strong a chess player for me now.

In order to be competitive, I had to find a way to slightly change the rules without making them much more complicated.

I am a board game designer in my free time and I published a few games.

Rules

This game follows the rules of Chess except as follows:

• Majority Rule: A piece can only be moved if, in total, there are at least as many pieces of its own colour in its file as there are pieces of the opponent's colour.
• A piece that cannot be moved cannot be attacking other pieces.
• If a piece cannot be moved, it cannot give check.
• It is possible to reach a stalemate due to the Majority Rule.

Examples

If it is White turn:

• The White King is not under attack because in the e file there are more White pieces than Black pieces. The Black Queen and Rook cannot be moved and they are not attacking.
• All White pieces can be moved.
• The Pawn in f4 can be moved because the number of pieces in the e file is tied.
• Bf3 is a stalemate because no Black pieces will be able to move

If it is Black turn:

• Only the Black Knight can be moved

Re6#: the Black King cannot be moved and is under attack
