@Shaub I like this workaround that you’ve proposed. It seems to me like it’s an improvement over what I had planned on doing. I had planned to just manually assign a different active player each time a pairing was made involving the departed player. That would get frustrating because it would need to be done every time Create Games is clicked after the player left. It would also be difficult to avoid creating a repeat pairing this way.
Your approach would be even easier to do if @haugstrup is interested in implementing a “Pause player” feature (suggested earlier). You could use this to leave the departed player indefinitely paused.
Your approach may hit problems if you end up with a number of rounds that’s more than a round robin. In that case, the Create Games button will refuse to get past the first round robin stage of pairings if anyone had not played against the departed player. You can use the Emergency Valve to get around this. I don’t believe that problem will come up if your tournament is shorter than a round robin.
Why is increasing the number of matches part of your strategy?
