Lewis Hamilton has moved to within 12 points of title rival Nico Rosberg following his masterclass at the rain-soaked Brazilian Grand Prix on Sunday.
The Briton's third consecutive victory ensures the Formula One championship will now be determined at the final race of the season in Abu Dhabi on November 27.
But after Rosberg crossed the line in second place at Interlagos, the title tussle remains firmly in his control.
But what of the different permutations ahead of the Duel in the Desert? Well...
If Hamilton wins at the Yas Marina Circuit, Rosberg must finish third or better to seal his maiden championship.
If Hamilton crosses the line in second place, Rosberg needs to be sixth or better. If the German finishes seventh the championship protagonists would be tied on points, but Hamilton would clinch the title by virtue of having scored more third places. They have both won on nine occasions this season, and would have also scored the same number of second places (four).
If Hamilton finishes third, then eighth place or better for Rosberg will be enough to win the title.
If Hamilton is fourth in Abu Dhabi, Rosberg will require just one point (10th) to be crowned champion. If Rosberg fails to score they would be tied on points, but in this scenario he would win the title having finished second four times compared with Hamilton's three.
Should Hamilton cross the line only in fifth, Rosberg will win the title regardless of where he finishes.
So there you have it - simple, right?
