How have I moved the goalposts?? Please don't just make accusations. Support them. If I am guilty I will hold my hands up and admit such, but you will need to demonstrate it. So, please, show where you think the goalposts have been moved. Otherwise please address the issues as raised. Omniscience means to know all: past, present, future. At any point in the time-frame, the next moment is known. If it is known beforehand then it can not be anything else. An action today was as set in stone a billion years ago as it was at the very start. If it can not be anything else then... any colour as long as it is black, etc. That is constraint. At least to the incompatibilist. That is the mechanism by which constraint arises out of omniscience: implication of the meaning of the terms. If you have/use different meanings then ymmv.
