One of my biggest wins was a $1000 buyin tournament where we started with 10,000 chips. Well I arrived late by about 45 minutes on purpose. I was playing live action and was up around $1400. But I thought that I would still have around 9500 chips. Well to my dismay, I only had 8700 chips after that 45 minutes. I believe that the blinds started at 50/100. The problem was that there were 3 players not at the table for 20 and one guy NEVER showed up for the tournament after paying or qualifying to play. I wasnt counting on more than 1 person to not be at the table. But I won that tournament anyway. There were 435 players and it paid $134,000 for first. So every tournament since then I arrive late, but usually only 25 minutes late or so.
I mention this story, in case you are wondering why some of the pros arrive 1-2 hours late to the main event. They want to conserve their strength and not be tired early into the day
