For online pairs games, there is no need to choose a movement as you would with a face-to-face game. This is because - unlike a club, where there is only one set of boards shared between the whole room - in online games all tables play the same board at the same time.
Therefore, we have no need for complicated movements in online bridge.
Instead, for each round, Pianola Play randomly matches each pair with another pair that they haven't already played.
For one-winner games, each pair will play against any other pairs in the game, regardless of starting position.
For two-winner games, all pairs retain their starting seats throughout (NS or EW) and they will be play against only pairs who began the game in the opposite direction.
