Real-valued chess

what if chess, but pieces weren't confined to only 64 squares? what if pieces were free? what if... real-valued chess?

This whole idea is inspired by The Adder. I wanted to make it possible to actually play the chess variant he suggested, so here you go.

Controls

• Click or drag a piece, then click where it should go
• Shift: snap to square centres
• A: show every point the enemy attacks
• Mouse wheel: scroll the move list
• Ctrl+Z: undo  ·  Ctrl+N: new game
• Right-click / Esc: deselect
• Q / R / B / N: choose a piece when a pawn promotes

Two players, one screen. Checkmate when the opponent has no legal move left.

The idea, the rules and the art all come from The Adder's video: https://www.youtube.com/watch?v=_jiQFW023ws. Go watch it!
