Jack of diamonds: taking it scores −10, giving a reason to win a trick.; Three, five or six players: remove cards so the deck divides evenly — commonly the two of diamonds and/or two of clubs.; Black Maria: the British relative, using the ace and king of spades as extra penalties.
Why people argue about this
People often assume that removing cards like the two of diamonds and clubs is just for fun, a quirky variation. However, they misunderstand the actual purpose: it's crucial for ensuring an even distribution among players, which maintains fair gameplay across different player counts. It's not about making tricks harder but about keeping the game balanced regardless of how many people are playing.
