To run fights without losing, follow these steps:

1. Take note of YOUR attack and defense strength from your profile page.
2. Click on the rivals list, and choose "Rob" (NOT Attack)
3. Once you are in your rival's hood, view "Rival's profile" and take note of their defense strength.
4. If YOUR attack strength is significantly higher than your rival's defense strength, you should win every fight against them. If not, start the process over with a new rival, instead of attacking.
