If you have ever visited the famous casino in Monte Carlo and played roulette, you will know that you never win big if you spread your stake equally over red and black.
Well, when the safety car came out, first in virtual and then a more real form after Max Verstappen piled into the Ste Devote wall, Mercedes wanted to win big and took a risk. It put everything on red.
