Crucial Position

WHAT HAPPENED

Move Played: a5

At move 85 White pushed the a‑pawn from a4 to a5. The move does not address any of Black’s immediate threats. Black’s king on f4 can capture the white knight on e3 (e3) or the pawn on f5 (f5). Moreover White’s pieces on b3, f2 and h4 are completely undefended, and the pawn push creates no new threats. By playing a5 White simply wastes a tempo and leaves the position vulnerable.

WHY IT'S BETTER

Engine suggested: Ke2

Engine’s top move is 85 Ke2. Moving the king to e2 directly defends the knight on e3 and steps out of the line of the black king’s possible captures. It also brings the king closer to the centre, where it can assist in stopping Black’s king infiltration and support the rook on e6. By contrast, a5 does nothing to stop the looming capture on e3 or f5 and allows Black to continue the attack with …Kxe3 or …Kxf5, winning material.

KEY PRINCIPLE

King safety first: When the opponent’s king is active, always consider whether your king can be attacked. Prioritize moves that defend vulnerable pieces and improve king placement over irrelevant pawn pushes.

Master Lens

The game featured a Maróczy Bind against the Accelerated Dragon, where White built a solid pawn structure and active pieces, leading to a long rook‑and‑minor‑piece ending that ended in a stalemate draw. The players showed how to squeeze the opponent in the opening, keep the king active in the middlegame, and avoid careless pawn pushes when the enemy king is nearby.

What The GM Did Well By Phase

Opening

White established the Maróczy Bind with **5.c4** and **6.Nc3**, controlling the key d5‑square and limiting Black’s central break. By playing **9.Bg5** and exchanging on g7 with **12.Bh6**, White removed Black’s fianchettoed bishop, further weakening Black’s control of the dark squares. This demonstrates the principle of restricting the opponent’s pawn breaks and improving piece placement before launching an attack.

Middlegame

After the queens were exchanged on **15.Qxc5**, White used the open c‑file with **19.Rac1** and later **39.Rc8** to infiltrate Black’s position. The king marched into the centre with **31.Ke2**, **34.Kc4**, and **37.Kd3**, turning the king into an active piece that helped support the rooks and stop Black’s pawn advances. The lesson here is that in rook‑and‑minor‑piece endings the king becomes a fighting piece; bringing it toward the centre can be decisive.

Endgame

White’s rooks dominated the seventh rank (e.g., **73.Re4+**, **75.Rb6+**) and created a passed a‑pawn, while the knight and bishop coordinated to restrict Black’s king. However, the critical mistake came with **85.a5**, a pawn push that ignored the immediate threat of Black’s king capturing on e3 or f5. The better move **85.Ke2** would have defended the knight and kept the king safe. This illustrates the key principle of king safety: when the opponent’s king is active, always prioritize defending vulnerable pieces and improving king placement over irrelevant pawn moves.
