i dont have tourney experience but in league play.. all the clubs and bars provide pizza in the middle of the game. I cant eat before or during a match. As far as practice goes I often times order a small sub while practicing and as soon as it shows up my game takes a nose dive as all I can think about is the sub lol SO I think id be in the group that has to eat prior to the game and then perhaps a small small snack during the event. Luckily I have a bad stomach and dont drink alcohol and I dont smoke so I have a leg up it seems. Although the only excercise i get these days is at the table
