I have no idea what happened in this game. I watched part of it last night, and early on, I thought that Jim Dean would have good chances to win with Black. But Tatev Abrahamyan is very resourceful, and I wouldn't be surprised if she had a winning ending at a certain point. (Knight and bishop often have problems coordinating against an enemy rook, to the point that Reuben Fine considered rook and two pawns vs. knight and bishop to be a win in the general case.)
Restrain, blockade, destroy, draw.
