I thought L was so clever for inventing Chesskers. One player plays by chess rules with chess pieces, the other player plays with checker pieces and follows the checker rules.
The only deviation from the standard rules is that there is no check, because capturing the King isn't the end of the game. The last man standing wins.
He won (not a surprise to anyone who has played against me in a strategizing game).
What was surprising is that it's actually a real game with official (different) rules!
