Improve ratings
But the most important thing to do is just have fun.
Obviously win the tournament, which will also improve your rating.
well, yes and no. Although it is true that if you win all your games in a tournament, you can't lose rating points. However, if you're so much higher rated than everyone else you won't gain many points either. And all it takes is one measly draw or loss and bam your rating plummets. That's why I ask if there is lots of money and or a title involved - because if there is, then it is worth it to be as high as possible in a section. Otherwise, you're better off being in the middle of a section (pre-rating order).
I presumed we were talking about the same tournament, rather than a choice between 2.
im in a tournament this sunday for USCF who thinks tournaments are to be won or improve ratings both are nice to do but what is more important for me to focus on comment answers
