I reckon that the two Day 1s will be for the same duration or until a certain number of players remain. At the Edinburgh tourney, we were less than a minute from ending day 1 when we were reduced to 20 players. When we resumed the next day, we then played one hand before the blinds increased.
I hope that we get the option of choosing which Day 1. Saturday would suit me fine and not just because Mark wants to play Sunday. As I live in London, it will only take an hour on the train so I don"t need to stay over.
It would be good if there were live and on-line satellites but I would prefer a ballot rather than a click fest. In the past, I have not been able to get to the computer at the set time.
