So, an optional rule in the core book offers Hooks - some troubling weaknesses that can make the story more interesting. I'm a big fan of such things (being a big time Fate DM), but I can't find any info on how to use Hooks.

Naturally, it's best to let players affect their own decisions with Hooks in mind - but I often use Risus with beginner players for whom it might be a bit much to figure out, plus I'd rather have it written down as a clear rule.

How would I approach using Hooks to give my players some penalties on their rolls in specific situations? (basically, how can I implement "Trouble" aspect from Fate into Risus?)
