Simple answer...and possibly wrong...last player to have the button. Actually, I read somewhere--don't remember where--you start w/seat one or the nearest occupied seat to seat one. That's how we color-up in my home game.
Ask BCC: Why does it take 6-8 months when you promised 4-5 weeks? How come you didn't look at the chips before you sent them out? Why does it take 6+ months for BCC to make good on a bad order after waiting 6-8 months in the first place?
I agree with Nexttime. In the tournaments I dealt in we always started at seat 1. I suppose if you didn't assign specific numbers before the start of the tournament that starting at the seat just after the button (small blind position) would work too.
