Questions & Answers about Je vois le piège, mais je ne sais pas où cacher le guerrier.
Why is cacher in the infinitive here instead of being conjugated?
This sentence uses an indirect question, which is exactly what your current lesson covers: a question word (où) followed immediately by an infinitive (cacher). Just like in English ("where to hide"), when the person doing the main action (je) is the same person doing the hiding, you can simply use the infinitive. It is a natural, concise way to say "where I should hide".
Why do we use savoir (je ne sais pas) instead of connaître here?
We use savoir because it is followed by a question word (où) and an action. Savoir is used for knowing facts, knowing how to do something, or before question words like where, when, and why. Connaître is strictly used for being familiar with a noun, like a person or a place. If you wanted to say "I know this warrior", you would use connaître.
Why does où have a grave accent on the u?
