Train the way you typically train, but lower the volume on the other lifts some. Unless its a national type meet, I wouldn't worry to much about where you place. Go there with the goal to improve. In most cases there are only a few people in every class.
Best meet lifts: 1040squat, 730 bench, 730 deadlift
Best total: 1040-680-730=2450
