After winning 8 games in a row, she loses 4 games in a row. 2-4* It looks as if Kichenok may have sussed out how to handle Anna's game.
Agreed - very likely Kichenok may have figured out how to handle Anna's game. Unlikely it was simply down to Kichenok especially losing eight games on the trot (with her ranking). Anna must have been doing something right.
