Rules HELP [FTC]

Hello, Our team (6376 Rambots) has been fortunate enough to compete in a Regional FTC tournament, and we need some clarifications. We don’t want any sudden match rules to pop up that we didn’t know about, which has happened before. Basically, we want to know what the most important rules that people could easily find loopholes or take advantage of (ex: End game contact, normal contact and pinning specs)
Any feedback is greatly appreciated! Thanks!
