My suggestion is sort of like the others, with a twist. If u r the type to get pumped when u r doing well, get REALLY pumped. Stay agressive, but not over the top PDW in your face with crotch chops agressive.
Ive always found that if u stay really pumped, & act like u KNOW u r going to strike to win, the opponent typically wont be able to do enough to make u strike to win. Just personal exp.
Personally, i would rather bowl head to head than anything else. Team tournaments, as well as the full sweeper style where u just bowl 3-5 games & thats that dont work for me. I wanna bowl 5 games, cut the field in half, bowl 3-5 more, cut to top however many they want, then do round robin match play, then stepladder.
Typically i can beat the 1 person i have to beat, its when im worrying about the other 2304982340298 bowlers that i tend to not do as well.
