This position comes from Game 2. Dmitriy and Phil are playing White, on top in the diagram. This play caught my attention for two reasons. The first was simply because Dmitriy and Phil chose the 5th best play, 0.07 down from best. Yup, they chose S (Split) = 24/23 13/11. The second, more interesting reason, was because I noticed that this plays more like 51S-21 than it does 61P-21. Dmitriy and Phil treated it more like 61P-21.
