WGM Natalia Pogonina in chessgames.com:
"Well, the score looks very grim for Ushenina. She is clearly not playing her best here. However, if we take a look at the actual games, then it's not THAT terrible.
Game 1: Anna had a comfortable advantage. Lost due to falling behind on the clock and messing up in time trouble.
Game 2: Hou Yifan got a slightly worse endgame as White and saved it.
Game 3: For some reason Anna went all-out as White and self-destructed.
Generally speaking, if the Ukrainian team manages to find lines leading to more positional middlegames and technical endgames, then their chances will be ok. The only real problem is that they are already trailing behind by two points.
Hou Yifan is playing fine so far, but I wouldn't say that she is showing anything special. It's Anna who's performing badly."
I`m not sure if Ushenia`s play is not affected by poor acclimatization. Actually it made me think about Carlsen`s chances in his match vs Anand.
