It wasn't a trap, but for one not 'game' for 'winning' and 'losing' analogy, you sure play with the idea. This was the point of my win scenario.
God wins, and my point is that He is more than just capable, He must win. There is no room for error with God.
In your chess game, God always wins. His Son will return. All wrongs will be made right. The only reason God could lose is if He chooses to, otherwise we have a Christian message closer to Yin/Yang.
Because God's knowledge could not have Him losing, you must concede He never makes mistakes (and Sanders was absolutely wrong).
Again, this means God is much closer to a virtual EDF than OV would admit. There is nothing that would be a 'new' move if God knows all there is to know past and present. I'm arguing for a better OV position here.
Leaving the game analogies behind, 'Very smart' isn't good enough. He has to be able to bring about His intention (win). God cannot fail, both because of who He is and what He has determined. There is no greater strength that can defeat God. There is no smarter being that can outsmart Him at His own creation.
"Very Smart." How smart? If God never loses, He knows future intentions and actions of men as old hat. There is no move man can make that He isn't prepared for. There is nothing man can do to thwart His intentions. If you begin to follow this line of logic to its conclusion, you'll be very close to EDF logically.
I believe this is the argument Rob was trying to make for several days now.
