Crucial Position

WHAT HAPPENED

Move Played: Nc6

Black moved the knight from b4 to c6 (Nc6). By abandoning b4, the knight left the square undefended, allowing White's a5 pawn to capture on b4 and White's bishop on c3 to seize the pawn on f6. The immediate consequence is a loss of a whole piece (the knight) and the weakening of the f6 pawn, while Black created no new threats.

WHY IT'S BETTER

Engine suggested: Na6

The engine recommends 28...Na6. From a6 the knight still protects the b4 square, preventing White's a5xb4 capture, and it also eyes c5 and c7, keeping the knight active. Na6 preserves material, neutralises White's threats on b4 and f6, and retains flexibility, whereas Nc6 concedes a piece without compensation.

KEY PRINCIPLE

Never abandon an undefended piece: Always check whether a move leaves a piece or a critical square unprotected. Protecting key squares (like b4) is often more important than chasing a seemingly active square.

Move #: 37

Endgame error compounded existing disadvantage

Master Lens

Black (GM) lost a French Exchange game after two decisive endgame errors – the piece‑losing move **28...Nc6** and the passive **37...Nb4** – which let White march his king to victory. The game illustrates the importance of always guarding vulnerable pieces and of generating active threats when under pressure.

What The GM Did Well By Phase

Opening

Black quickly completed development by castling on move 6 and placing the bishop on d6, which helped secure the king (king safety) and control central squares. By exchanging the light‑squared bishops early, Black reduced White's attacking potential and kept the position balanced (simplification).

Middlegame

After the queens were traded, Black kept material equality by exchanging rooks on c1 and then activating the queen on a8, showing good piece coordination (piece activity). The exchange of the rook for a pawn on move 24 kept the pawn structure relatively sound, demonstrating how to trade down when under pressure.

Endgame

The critical mistakes occurred in the endgame. First, **28...Nc6** abandoned the defended b4 square, allowing White's a‑pawn to capture on b4 and win a piece – a clear example of why you must never leave a piece or key square undefended (material preservation). The stronger continuation was **28...Na6**, which would have kept the knight protecting b4 and stayed flexible. Later, **37...Nb4** was a passive move that did nothing to stop White's king infiltration; the better move **37...g5** would have created a passed pawn and forced White to respond, illustrating the principle of creating active threats (counter‑play) in a defensive position.
