The thing is the claim has been made that "god" does know the future. I.e. it's a given for this argument. If the future is known (i.e. the foreknowledge is infallibly true) then there is, and can be, no choice. We're all following (unkown to us) a pre-written script which only "god" has read. If "god" knows your choices then can you choose other than what "god" predicts? If yes then, by definition, he/ she/ it didn't know. If no then then there wasn't actually a choice.
