The reference cycle
Pagat’s American four-player account passes three cards left, then right, then across, then holds with no pass. The sequence repeats. Select the cards to give before inspecting the incoming cards.
Use the diagram deliberately
The seat labels are a view from above, with players facing the centre. Check the recipient table as well as the arrow, particularly when explaining left and right to someone seated on the opposite side.
A teaching routine
During open-hand practice, have each person name their recipient before placing the selected cards face down. Pause if the descriptions disagree. This routine is a learning aid, not a suggestion about which cards to choose.
Other settings
A group or app may use another cycle. The diagram shows one named reference, not an automatic statement about your current table.
