Chess Board 4.0 by IceFlame22. No command blocks. Minecraft version 1.19.4.

This chess board is a major improvement over my previous ones. It is much faster, supports castling, pawn promotion, and en passant, and even states the algebraic notation of your moves as you play them. However, the board is still unable to enforce the rules of chess. There is a user guide included in the world which will provide information about how to use the chess board properly.

Credit to GreenJab for the idea to use powdered snow instead of redstone lamps.
