Good point. This one is scheduled to run 3 hours, and the home tourney sites I've looked at for our own home games have blind scheduled that seem reasonable and are suggested to conclude in 3 hours. I can hope for that, but I think your concern is one I'll definitely have to plan for.

It's a charity game, so I expect a lot of novice players, which means calling stations, which means scary suck-outs at the end which could be painful combined with the turbo-like blinds.
