We have a potentially epic race ahead of us tomorrow. As the duel between Hamilton and Verstappen resumes. It is likely to be a wet race, so it is all about who is better prepared for the conditions. Being a wet race, the Williams may well win the race; which would be spectacular.
I think Russell would try to take the lead. How Verstappen responds to the combined attack of Russell and Hamilton would determine who wins this race. Russell has nothing to lose, and Verstappen has more to lose being in the championship fight and eight points adrift. so it would be interesting to see what he does when the Williams fight him for the lead of the race on the first lap. The clever old head on Hamilton would very much understand this situation and would be looking to capitalize on it.
Realistically, we would expect the Williams to fade backwards as the race progresses. Whatever happens, Russell cannot end up taking Hamilton out in the first lap tussle. That would effectively destroy his chance for the coveted Mercedes seat spectacularly.
