Veoma nasumičan geometrijski lanac | Pretty random geometry chain #3

Niki and Kyle play a triangle game. Niki first draws \triangle ABC with area 1, and Kyle picks a point X inside \triangle ABC. Niki then draws segments \overline{DG}, \overline{EH}, and \overline{FI}, all through X, such that D and E are on \overline{BC}, F and G are on \overline{AC}, and H and I are on \overline{AB}. The ten points must all be distinct. Finally, let S be the sum of the areas of triangles DEX, FGX, and HIX. Kyle earns S points, and Niki earns 1-S points. If both players play optimally to maximize the amount of points they get, who will win and by how much? Write your answer in the form "XY" where X is the first letter of the winner's name and Y is a difference rounded to 2 decimal places.
