Biden is playing 3D chess

I literally did not understand a single word you just said

Ok, let me dumb it down for you:
Biden smart. Playing dumb. Surprise Trump with smarts at debate, or he just really does have dementia.

I feel there's a chance he's faking, but even if he were to be. He still doesn't stand a chance he was never quick witted only quick to anger and still displays this trait.
Trump will ask him what drugs he took if he suddenly is lucid again.
Joe gets tired from an afternoon out to the icecream shop so shortened debates seems a likely too.
