When you start an Instant Tournament, you will be dealt deals from a past tournament you have not played before,

What are those tourneys? understand it must be a sort of human vs 3 robots. are these other $0.25 robots tourney with specific start time? are all the 8 hands of the instant one fetched from 1 and only 1 "past tourney you have not played before"?

Quote

and have your scores compared against 14 players in those tourneys.

how many players were there originally in those tourneys from where hands are fetched? more than/exactly 14?
are the original players from the old tourney earning master points as well (when the tourney was hosted)?

I don't have all of your answers. Perhaps someone else can help.

I confirm that all of the hands come from a single tournament. Of that I am confident.

I am also pretty confident that the tournament pool is the $0.25 8-board robot duplicates.

I am also pretty confident that the pool contains only those tournaments that had at least 14 players.

Where the number of players exceeded 14 in the original, I do not know how the comparisons are selected.

If you play in a BBO Instant Tourney, it was originally a $0.25 BBO Robot Duplicates. If you play in an ACBL Instant Tourney, it was originally a $1 ACBL Robot Duplicate.

All the boards come from a single tourney with at least 15 players. We select 14 random players from the tourney to compare you with.

The original players only earned their original masterpoints, they don't get any points for the replay.

We also try to select tournaments where the bots were running the same version of GIB as is currently in use. If, somehow, you've played them all (either in their original play or replaying them as an IT) we'll fall back to the next most recent version, and so on. This is why we've locked down visibility of robot tournaments in myhands: to prevent players from looking up the tournaments of the opponents and finding the original hands.

Of course, it's easier "to select tournaments where the bots were running the same version of GIB as is currently in use" when it's been 6 months since the last update...

Well, we used to use tournaments that were something like a year or more old, so they were several GIB revisions out of date.
