Mike....I know a lot about Northern California cardrooms. I have researched( I would say) probably hundreds( maybe 1000+) of hours over the last 15 years. Sometimes I would be up all night.
I definitely do not know everything as I learn something new every day that I look.
If you have any questions about a specific area or cardroom, I'll do my best to have an answer. I'll never give out false info, but I might have an educated guess based on the facts that are available. And I'll state that in my response. Sometimes it's hard to actually connect the dots with some of these clubs.
