I don't see why this particular pairing is caused by the large number of rounds.
If there were only 7 rounds instead of 11, wouldn't the pairings up to this
point be exactly the same? Does the pairing program take into account the number
of rounds?

Correct me if I'm wrong, but this many rounds is definately good if the
participants are evenly matched. There are a lot of weak participants in this
event, but I still don't see what is gained by having fewer rounds. It seems to
me that the more games that each program plays, even against weak opposition,
should still help improve the overall result.

As an aside, Fritz' Bucholz will probably be shot by this pairing, as Junior and
Shredder will probably be the two programs that don't play FIBChess.
