I suppose that would be something like "jeder Trick"

I put this too. I think it's better idiomatically.

As I understand it: "wissen" is for knowing facts; think of it as "I am aware that...". "Ich weiß, dass meine Schildkröte ist verrückt!" = "I know that my tortoise is crazy!". "Kennen" is for knowing people, places, etc. -- think of it as "I am acquainted with...". So, "Ich kenne diese Schildkröte!" = "I know this tortoise!" (also "kennen" for I know this song, this bar, this street, etc.). Native speakers, feel free to correct me!
