I'm outlining the plot for a scifi screenplay. I have the main characters, premise, the first half of the story, and the climax thought out. I don't want to bore you with details, but the story involves an enemy who can perfectly anticipate your moves. The main character needs to figure out how to defeat this enemy.
The problem is that I don't know the solution to the logical problem I've created here. I don't know how this enemy might be defeated (I have ideas for the climax, but I'm not sure how to resolve the mini conflicts that lead up to that climax). I'm sure if I keep writing something will come to me; it's happened in the past when continuing to churn out words generates ideas and connections and solutions. But I seem to be at a point where I really do need to resolve this to connect the midpoint of my story and the ending.
Do you have any ideas for how I can keep writing when I don't yet know the logical solution to a problem the main character is facing? Any ideas for what I could focus on writing, till the idea presents itself?
Details if they're useful: I'm aiming to write a screenplay. Right now I'm writing the treatment, so I'm trying to have every major scene and event down on paper (based on what I have I think this will come out to 10-15 pages).
