This chess variant recently released and it's really great - both players have a SECRET drawback, and there's a pool of like 150 secret drawbacks.
This makes the game much more interesting, as there's a meta of trying to trick your opponent into taking weak pieces, make 'bluff' threats, even disguise your drawback as something else, or predict your opponent's drawback.
Gameplay starts 1:00, I explain the basic rules before then though.
