Just posted all of my games from BAT - looks like I didn't make too many big mistakes, but I blew two games against Ian and Joel Sherman and my shenanigans against Cesar could easily have cost me a third.
In a lot of these games I made little mistakes early that ended up having a really significant impact on the course of the game. Sometimes I hear people argue that small errors at the beginning of the game don't matter as much as saving time for the endgame, but against great players you really have to choose carefully early to make sure that you have all of the options you want later (and prevent them from doing what they want to do as well).
Here's my game with Rafi where I made some inaccurate choices in the first few moves:

here Here are a few positions where I'm still not sure what I should've done:
