Key positions
The moments that decided it
11. Bg5 — the swing begins
With his king still uncastled, White plays 11.Bg5, developing the bishop actively. But the evaluation swings from roughly even to nearly three pawns in Black's favor. The safer bishop move to e2 kept things balanced — this one hands Fischer the initiative.
11...Na4 - Punishing the Mistake
White's bishop move already cost ground, and Fischer presses immediately. The knight jumps to a4, attacking, and it's the engine's own choice. The follow-up, taking on c3, is coming next — each move forcing a reply, each one tightening the screw.
The Queen Sacrifice
Then comes the moment. Fischer plays Be6, leaving his queen hanging. Byrne takes it, the bishop captures on b6. But the evaluation swings from minus two-point-eight to minus six-point-seven — the stronger try was Qxc3. Taking the queen wasn't greed rewarded; it was a trap. Fischer's pieces are about to pour forward for far more than a queen.
36. Kf1 — Into the Mating Net
The king is already under fire and the position is already lost, but here White has a choice. 36.Kf1 is played, walking straight into a forced mate in five. The safer try was Kh2 — it wouldn't have saved the game, but it wouldn't have ended it this fast either.
41...Rc2#
The White king, driven from home since move thirty-five, finally runs out of squares. Fischer delivers the final blow: Rc2, checkmate. It wasn't the only mating move available - the bishop to a3 mated too - but it didn't matter. The king hunt was over.
