Actually I don't drink much, and I never start drinking from the very beginning. The first 1.5-2 hours I'm sober as a judge. Also, the quantity of drinks in my house is pre-established so that I wouldn't drink too much. That's why they can run out if the tournament is too long.
I was thinking about it. At first I do play mostly for points to qualify for the the Grand Final. And when the goal is achieved, it seems like it's more advantageous to play in some GTD tournaments where the prize pool is usually bigger than all the buy-ins combined. But it's advantageous only money-wise, while I'm looking for the entertainment in the first place. And it is so much fun playing with you guys, and since it can be the last Bitcointalk Poker Series in the observable future, I'd rather play in those 2 games.
