Why people argue about this
People often assume that the order of suits (spades, hearts, diamonds, clubs) is arbitrary and don't realize it's a crucial aspect for determining trump suit in Duplicate Bridge. They might think it could be any order they prefer, but actually, it must follow the strict hierarchy as stated to ensure fairness and consistency across all deals.
