This was not normal chess.
Grading was simple. A: Your side wins and your piece lives. B: Your side wins and your piece dies. C: Your side loses and your piece lives D: Your side loses and your piece dies. F: You touch the main board, board cart, or otherwise interfere in the simulation. This was the ONLY way to fail the simulation.
Great post on reddit about a teacher who used chess to (unbeknownst to them) teach his students about war. Absolutely cracking.
