Rook tier · Attacking Maestro · plays the King's Indian Defense
Hannah plays every King's Indian as if the result depends on her kingside attack, and often it does. At 47 she has a strong feel for the moment to push ...f5, then ...f4 and ...g5, and for the piece sacrifice that breaks open a White king. Her book gives White the centre on purpose, because a big centre that closes with d5 is exactly what sets up the race she enjoys.
She is at her most dangerous when White is slow on the queenside and her pawns are already rolling. Positions without a target bother her: if White's king is well covered and there is no hook to attack, she has to switch to a long positional game she finds less exciting. Her commitment to the kingside can be total, which sometimes leaves her queenside thin. Hold the kingside with as few weaknesses as possible, and her attack can run out of fuel before your counterplay does.
At 2226 ELO, Hannah plays at master strength. Outright blunders are rare, so you need a sound opening, a clear plan and accurate calculation in sharp moments. A draw against her is a good result; a win means you played a very good game.
Hannah 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.
