Fabiano Caruana and Leinier Dominguez both scored back-to-back wins in rounds 6 and 7 of the Sinquefield Cup to join Wesley So in the lead of the standings. Caruana, in fact, defeated So on Tuesday, and he did it in remarkable style. By beating the former sole leader, Caruana also secured first place in the Grand Chess Tour and crossed the 2800-mark in the live ratings list! | Photo: Lennart Ootes
