Personally, I thought the structure was absolutely perfect (but then I would, wouldn"t I?). However the finish was a little too late for a Sunday night, given that most people play the game with every intention of going to work on Monday morning.
We started at 14:30 on Sunday, but I was at the casino at 13:00, and the place was already starting to buzz..... don"t see why we couldn"t have started at 14:00. Then, if the casino had been a little more organised around the dinner break, and the break had lasted for one hour max, that would have cut a total of 1.5 hours from the day, and the game would have ended around midnight...... in my opinion, that would have been spot on.
One other thing to take a look at is the sizing of the antes. In some levels the ratio of ante to small blind was 10:1.... I think the highest I saw it was 6:1. If the antes were just slightly larger and running between 4:1 and 6:1, the pots would have been more attractive for stealing, and would have induced more play (and stopped all that silly passive folding when down to the lasst three
)
Overall though, the structure was as good as I"ve ever played - I loved it.
