In the quarterfinals, I expect a full series between Team Yandex and Team Spirit. Yandex is in good form, but Spirit is capable of putting up a fight. Both teams have experience and knowledge of each other's playstyle. I predict a total of more than 2.5 maps, as map exchanges are more likely than a clean outcome. Their encounters usually end with a close result. My forecast: total of more than 2.5 maps.
