Royal Reserve Chess

Welcome to Royal Reserve Chess

Royal Reserve Chess is a premium, tactical chess variant that takes the classic game of kings and adds a deep layer of resource management. In this game, the battlefield starts minimized, and victory goes to the player who best manages their active army and reinforcements.

🌀 The Core Mechanic: The Reserve Pool

Unlike standard chess, you start the game with a minimal set of active pieces on the board. The rest of your army remains in your Reserve Pool:

• Rooks: 2 in reserve
• Knights: 2 in reserve
• Bishops: 1 in reserve
• Pawns: 5 in reserve

⚔️ How to Play

On your turn, you must make a strategic decision:

1. MOVE: Make a standard chess move with any active piece on the board.
2. DEPLOY: Select a piece from your reserve pool and place it onto any empty square on your half of the board (Rows 1-4 for White, Rows 5-8 for Black).

🛑 Deployment Constraints

• No Direct Captures: You cannot deploy a piece directly onto an occupied square to capture an opponent's piece.
• No Instant Checks: A deployed piece cannot immediately declare check on the opponent's King on the turn it is deployed.
• Pawn Placement: Pawns cannot be deployed on the 1st or 8th rank.
