Rook tier · Counter-attacker · plays the King's Indian Defense
Anna is a counter-attacker: she lets you come forward, absorbs the pressure, and then strikes back where you have overextended. At 49 she has the experience to play the King's Indian the way it was designed, giving White the centre in the opening and waiting for the right moment to hit it with ...e5 or ...c5.
She is at her best when White commits early to an aggressive plan, because every pawn advance becomes a target for her. Her pieces work well together behind a solid pawn chain, and she reacts quickly to loose squares. What makes her uncomfortable is a calm, flexible White setup that leaves her nothing to counter. If your pawns stay compact and you keep the option of several different plans, she has to take the initiative herself, and that is not how she prefers to play.
At 2098 ELO, Anna rarely gives material away for nothing. She is held to that rating by the engine, so you will see the occasional inaccuracy in quiet positions, but tactics are usually spotted. Games are won by building a better position over many moves and converting it carefully.
Anna plays the King's Indian Defense: ...Nf6, ...g6, ...Bg7, ...d6 and castling, letting White build a big centre and then striking at it with ...e5. In the main Mar del Plata line the centre closes after d5 and both sides attack on opposite wings, Black with ...f5 on the kingside.
