Depending on where one puts the line between expert and intermediate, I'm on one side or the other. I've played twice on the last day of an NABC+ event. With two kids and a full-time job developing software, I don't get to play as much as I'd like. I'm interested in theory, laws, & tournament organization; I've been involved in rulemaking for chess and Scrabble in the past.
Plus... it's free!
