Rook tier · Theory Encyclopedia · plays the King's Indian Defense
Ingrid has a library in her head. At 23 she can recite King's Indian main lines deep into the middlegame, and her opening choice reflects that: a defence where the theory is enormous and the reward for knowing it is a ready-made plan. She lets White take the centre, castles, strikes with ...e5, and in the closed structures she already knows where every piece belongs.
Her confidence grows with familiarity. When the position matches something she has studied, she plays with purpose and rarely wastes a tempo. Unusual pawn structures are another matter, because then the plan has to come from her own judgement rather than memory, and she is more inclined to drift for a move or two. She rarely falls for standard traps, so cheap tricks in well-known lines are a waste of effort. The practical route is a sound system with less theory behind it, followed by a middlegame where understanding counts for more than recall.
At 2162 ELO, Ingrid 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.
Ingrid 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.
