Sunday brought smiles for the Red Bull and Ferrari teams. In the hands of Verstappen, the Red Bull was about as fast as the black-and-orange McLarens, and while second was the best Verstappen could do in qualifying, the gap to McLaren's Oscar Piastri was measured in the hundredths of a second.

Verstappen's initial start from the line looked unremarkable, too—the Mercedes of George Russell seemed more of a threat to the pole man. But Verstappen saw an opportunity and drove around the outside almost before Piastri even registered he was there, seizing the lead of the race. Once the Red Bull driver was in clean air, he was able to stretch the gap to Piastri.

Getting past someone is notoriously hard at Imola. In a 2005 classic, Fernando Alonso held off Michael Schumacher's much faster car for the entire race. Even though the cars are larger and heavier now and more closely matched, overtaking was still possible, like Norris' pass on Russell.

Undercut? Overcut?

But when overtaking is as hard as it is at a track like Imola, teams will try to use strategy to pass each other with pit stops. Each driver has to make at least one pit stop, as drivers are required to use two different tire compounds during the race. But depending on other factors, like how much the tires degrade, a team might decide to do two or even three stops—the lap time lost in the pits by stopping more often can be less than the time lost running on worn-out rubber.

In recent years, the word "undercut" has crept into F1 vocab, and no, it doesn't refer to the hairstyles favored by the more flamboyant drivers in the paddock. To undercut a rival means to make your pit stop before them and then, on fresh tires and with a clear track ahead, set fast lap after fast lap so that when your rival makes their stop, they emerge from the pits behind you.
