Why don't GMs play low rated players with material disadvantage for streaming purposes? That sounds to me as a chess fan that could make for very fun videos. The question I would like to answer is what material disadvantage would put Magnus at the same level of a 1000 rated player? Chess allow for very interesting combinations and I don't think he would beat even a 700 rated player if he starts with a king and a pawn. So how many and which pieces is the minimum he needs?
