CHT,
There are deeper things that could have kept Bridge out of the greater alliance.
I saw some of the preliminary organizational models, which were structured very similarly to Bridge. That similarity being that players would be registered with this new entity so they could compete in SCYSA. But unlike the relationship with between Bridge and SSC/JIYSC, if bridge were to move it's Challenge players (and Classic U12s) to this new organization, they would have no players left, and therefore the club would cease to exist. For some of the skeptics out there, it could have been viewed as a cleverly conceived way to eliminate Bridge FA.
