Cori Tello, Jorge Moises – Radjabov, Teimour

2569 2013 · White wins (resignation, time or agreement)

In 2013, Cori Tello, Jorge Moises (2569) met Radjabov, Teimour (2733) in a classical King’s Indian: d4-d5 space, the standard ...f5 counterplay, and a wide-open middlegame once the pawns came off on e3. Both sides held up well — 91 % of White’s moves were at least good, 87 % of Black’s. The swing came with 27...Rf6, a mistake that moved the evaluation from 0.0 to +1.8. White let it slip with 29.Qd5+, a missed opportunity that shifted things from -2.8 back to 0.0, and then 30...Qf2 handed everything over, from 0.0 to +4.4. The club lesson: in sharp positions, two loose moves can flip the game twice. White won, 1-0.
