Dan, I believe there is a rule that 50% of players is the maximum that can advance in multi-round tourneys. Unless there are ties, as what happened in round one of Forts. Since there are now 9 players (instead of 8), the 2nd round was put into groups of three. This is because of the max. group size as determined by TD. If there were no ties in round one, eight players would have advanced, and there would have been two groups of four, where two can then advance to round three. So, with a group of three, the only way more than one can advance is if there are ties.
Hope this helps.
As you can see below it clearly says 2 players advance, not 1. This may have been the second round in the tournament but it still says nowhere that only 1 player will advance.
This probably has something to do with the round only have 3 players, instead of 4. I still feel robbed of my rightful place in the tournament, as it says nowhere that only 1 player will advance. Chess.com needs updating because I'm sure that I'm not the only one that was expecting to go through.
