I'll send you to Chess24's report (and Jan Gustafsson's video, included therein) for the details, but will report that Wesley So won a very nice game against Ding Liren from the white side of a Classical King's Indian to take the lead in the Bilbao Final Masters. He has three points (Bilbao uses 3-1-0 scoring), Ding has zero, and Viswanathan Anand and Anish Giri have one point apiece after drawing with each other.
