Cards are dealt face down, one at a time, into four hands of thirteen cards, each placed face down in one of the board's pockets (Law 6B); No two adjacent cards from the deck shall be dealt into the same hand (Law 6B); The recommended procedure is to deal in rotation, clockwise (Law 6B)
Why people argue about this
People often assume that dealing cards face down one at a time is just for aesthetics, forgetting that it's crucial for ensuring no two adjacent cards end up in the same hand, which could lead to awkward or unfair hands. The confusion arises because they overlook how this meticulous process prevents strategic leaks and maintains the integrity of the game’s randomness.
