" Send your first move as White to your opponents as indicated below.
Player #1 receives first move from 2,3,4; Player #2 sends to 1, receives from 3 and 4; Player #3 sends to 1 and 2, receives from 4; Player #4 sends to 1,2,3."
When is Player 1 supposed to send his first moves as white? Are all six games not played concurrently,but 3 at a time?
Player 1 waits until he receives the White move from each of the other players, then with Black can reply to that move and also send his White move to that player on the same card. You play all 6 games at the same time.
