It's a small event, with only four players involved, but a very prestigious one. The Bilbao Final Masters is a double-round robin featuring Viswanathan, Anish Giri, Ding Liren and Wesley So. Play starts at 4 p.m. local time (= 11 a.m. ET) each day, with a rest day on Thursday in between the first and second cycle. The first round pairings are So vs. Ding and Anand vs. Giri.
