	move #	position	classification	description
Move #: 22 Move: Bh7 missed win Midgame missed winning continuation	22	Bh7	missed win	Midgame missed winning continuation
WHAT HAPPENED Move Played: Bh7 Black played 22...Bh7, retreating the bishop from e4 to h7. The move does nothing to stop White's active threats (a6, e4, f6) and leaves the a6 pawn completely undefended. White's bishop on e5 remains unprotected, and Black's own king side threats (b2, d4, g2, h5) are unchanged. By moving the bishop away, Black missed a concrete winning tactic. WHY IT'S BETTER Engine suggested: Re8 The engine’s top move 22...Re8 places the rook on the open e‑file, directly attacking the undefended white bishop on e5. After 22...Re8 White is forced to address the attack, and the continuation 23.Bxf6 wins material for Black (the knight on f6 is lost and Black regains the bishop). Re8 also neutralises White's e4‑f6 threats and prepares to consolidate the extra material. In contrast, Bh7 is a quiet, non‑forcing move that leaves Black’s material balance unchanged and allows White to keep the initiative. KEY PRINCIPLE Seek forcing moves that win material. When you have a tactical shot (like Re8), play it immediately; retreating a piece without purpose can squander a winning opportunity.
Move #: 45 Move: Rxc6 excellent Endgame found best move in complex position	45	Rxc6	excellent	Endgame found best move in complex position
WHAT HAPPENED Move Played: Rxc6 Black captured on c6 with 45...Rxc6, taking the undefended white pawn on c6. The capture removes White's passed pawn, gains a pawn and opens the c‑file for Black’s rook. White’s threats on e6 and f7 remain, but Black has eliminated a key pawn and kept the material edge. WHY IT'S BETTER Engine suggested: Kh7 The engine’s suggested continuation 45...Kh7 is a purely defensive king move that does not address the material imbalance. By playing Rxc6, Black exploits the fact that the c6 pawn and the f6 rook were both undefended, converting a passive position into a clear material advantage. After the capture, Black can later activate the rook, defend the king if needed, and still keep the initiative, whereas Kh7 merely sidesteps the threat without gaining anything. KEY PRINCIPLE Capture hanging pieces. Whenever an opponent leaves a piece undefended, seize the opportunity to win material; concrete gains outweigh quiet king moves in a winning position.

Master Lens

Hikaru (Black) employed the Modern Defense to launch a rapid pawn storm on White’s king side, then steered the game into a complex middlegame where he eventually seized a material edge, and finally converted that advantage in the endgame with precise rook activity. The game ends with Black’s win after White resigned.

What The GM Did Well By Phase

Opening

Hikaru accepted White’s early h‑pawn push and answered with ...g6 and ...Bg7, preparing a fianchetto that controls the long diagonal (a fianchetto). He then used the pawn moves ...a6 and ...b5 to gain space on the queenside while his king stayed safe, showing how a solid pawn structure can coexist with active piece play.

Middlegame

After both sides castled, Hikaru placed his rook on the open e‑file with **24...Re8**, a forcing move that attacked White’s bishop on e5 and forced a defensive reply. Although he later chose the quieter **22...Bh7**, the earlier **...Re8** illustrates the principle of looking for moves that create immediate threats (forcing moves) to win material. Throughout the middlegame he kept his pieces coordinated, especially the rook and bishop, to pressure White’s weak pawns on a6, e4 and f6.

Endgame

When White left the pawn on c6 undefended, Hikaru captured it with **45...Rxc6**, gaining a pawn and opening the c‑file for his rook. This concrete gain turned a passive position into a clear material advantage, demonstrating the importance of grabbing hanging pieces (material advantage) rather than making idle king moves. He then used his rook on the seventh rank and his active bishop to restrict the White king, converting the extra pawn into a winning endgame.
