This is my first time playing in a tournament like this. 10 players, RR format. 5 games from Feb 15-17 and then 4 more 2 weekends later. The pairings are already out, and of the 9 other players, I've played 7 of them before. This is definitely a new experience for me (this is the first year I was rated highly enough to earn an invite and just barely at that...I'm the 9th highest rated out of 10). My roommate is also playing and he's more towards the middle of the pack, but did tie for first in this event last year. We've been combining our knowledge to prepare for our first weekend of games (mostly opening preparation since between the two of us we mostly know what our opponents will play). Have any of you guys played in something like this before, and do you have any advice?
Edit: I wanted to add that other than a 2300 (who I have drawn before), everyone else is either floored at 2200 or lower than 2200. So it's a pretty even field, and I shouldn't feel like there are any guarenteed losses.
