I've noticed a pattern with my tournament performance: I start off strong, but around round 3 or 4 things start to fall apart and by the end I'm in the middle of the pack. My two store championships this year ended up (in order): WWLWLL (which is pretty typical) and WWMLL (going into round 3 of swiss ranked #1, which is a stronger start than I'm used to).
I take some caffeine in the morning (and am still wide awake past midnight, so I'm not going to take more), have snacks and get dinner, and bring water.
I realize that some of it is that I end up going up against the players that are in contention to take 1st, but just chalking it up to that seems defeatist.
Any suggestions for ways to keep a solid game towards the end of a long day? Thanks!
