My brother and I made this 15 by 15 squares chess board that uses two sets of pieces minus a pawn and king for each color.
We have already played a game and find it extremely fun and interesting, but a lot to manage in our heads as there are so many options.
We decided that we might need to change some of the rules - like how pieces move or how they are initially set up. Right now we have each side set up as following.
P P P P P P P P P P P P P P P R N B R N B Q K Q B N R B N R
We figured this provided a fair amount of protection, but is there a better layout? For instance, should queens be on one side of the king?
Queens remain very powerful, but bishops massively increase in power compared to the other pieces since they can cover so much distance. Rooks are difficult to move out as usual which is fine, but knights and pawns are pretty hard to get into the middle game.
We had a few ideas to fix this issue. We thought we will have pawns be able to move either 1, 2, or 3 spaces on their first turn. We are also considering giving knights a larger ‘L’ shape (not sure exactly what shape - suggestions welcome).
And then there is castling to figure out. We had an idea to give the king the ability to either castle with the nearest rook when he can under usual conditions when no pieces are blocking... or with the furthest rook if he can under usual conditions when no pieces are blocking.
I’m asking for advice on set up and rules that maximize fun gameplay and strategy. Any creative suggestions are welcome, but I’m also looking for some real logic to back up most ideas. Try to notice potential flaws with having a giant board and how to fix them by modifying set up and rules.
