I wasn't sure if this type of event has ever been run or if there would be any interest so I thought I would throw it out here for discussion. I understand that it would be a long day for a TD (and maybe players), but hopefully multiple people could TD and allow each TD to also participate.
The format would be a singles one round tournament, but with a flex time start. I would think the time would be similar to the club championships this year where you could show up and play anytime between 8am-3pm (last card out at 3pm). The twist would be that a single person could play multiple rounds and the best round would be used to determine the winner.
So say Greg would show up at 9am and pay $10 + $5 for CTPs to play a round. Greg ends up scoring a 59. But Greg knows he could have played better, so he gets some lunch then comes back at 1pm to play another round. He must pay the same $10 entry and $5 CTPs just as a new player, but would get a second chance to get a better score. If players wanted to stick around and if someone beats them out then they could pay in again to try to win their top spot back.
Just an idea.
