Crucial Position

WHAT HAPPENED

Move Played: Qa5

White moved the queen from d2 to a5. The move attacks the undefended a7 pawn but does nothing to address the most urgent danger: Black's queen on b3 is attacking the unprotected a4 pawn. After Qa5, Black can simply capture a4 (Qxa4) and also keep all other threats (a4, b5, d1, d3, d6) alive. No new defensive resource is created and White forfeits the chance to exploit Black's queen, which is completely undefended on b3.

WHY IT'S BETTER

Engine suggested: Rb1

The engine's top move, 26.Rb1, attacks the queen on b3 directly. The rook from d1 slides to b1, hitting the queen and forcing it to move or be lost, while simultaneously defending the a4 pawn indirectly by removing the immediate queen threat. Capturing the queen yields a decisive material advantage (queen for rook) and eliminates Black's dangerous threats. In contrast, Qa5 merely attacks a pawn and allows Black to retain the queen and continue with threats, missing a winning tactic.

KEY PRINCIPLE

Never ignore an undefended enemy piece. When the opponent's queen (or any high‑value piece) is hanging, your first priority should be to win it or force its retreat, even if you see a peripheral target. Tactical awareness outweighs slow positional ideas in such moments.

Master Lens

Hikaru (White) won a sharp Nimzo‑Larsen Attack by developing his pieces quickly, exploiting Black's unprotected queen in the middlegame, and then converting a passed pawn into a new queen. The game shows how active piece placement and tactical alertness can turn a seemingly equal position into a win.

What The GM Did Well By Phase

Opening

Hikaru fianchettoed his bishop with **5.g3** and **6.Bg2**, then placed the queen’s bishop on b2 with **2.Bb2** to control the long diagonal (a1‑h8). He completed development by castling on **15.O-O**, keeping his king safe while the rooks were ready to enter the game. This demonstrates the principle of rapid, purposeful development and king safety before launching an attack.

Middlegame

When Black’s queen landed on the vulnerable b3 square, the strongest continuation was **26.Rb1**, attacking the queen directly and forcing a material win. Instead, Hikaru played **26.Qa5**, which missed the chance to win the queen. After correcting the oversight, he used the active bishop on c5 (**27.Bc5**) and captured the a7 pawn (**28.Bxa7**), then won a rook with **30.Nxd7**. These moves illustrate the importance of always looking for hanging high‑value pieces (tactical awareness) and then converting the gained material into a passed pawn.

Endgame

With the extra material, Hikaru pushed his b‑pawn forward, promoting it to a queen on **35.b8=Q+**. The new queen, together with his remaining rook, created unstoppable threats, leading Black to resign. This shows how a passed pawn can become a decisive weapon (pawn promotion) when supported by active pieces.
