Crucial Position

WHAT HAPPENED

Move Played: Rd3+

Black chose 44...Rd3+, moving the rook from d7 to d3 and delivering a check on the white king on g3. The check forces White to respond (the game continuation shows 45.Kf2), but the bishop on e5 remains on the board and the rook on d7 vacates the d‑file, leaving the pawn on b5 and the rook on e4 unprotected. White’s rook on c5 stays active and the pawn on c5 is still undefended, so Black’s material balance does not improve.

WHY IT'S BETTER

Engine suggested: Rxe5

The engine’s 44...Rxe5 exploits the hanging white bishop. After 44...Rxe5 45.Rxe5 (forced) 45...Rxe5, Black trades the rook on d7 for the bishop and immediately recaptures on e5 with the rook from e4. The result is a net gain of a rook for a bishop (+2 material). By playing Rd3+ Black forfeits this forced winning exchange, wastes a tempo, and allows White to keep the bishop and maintain the pressure on the b5 pawn. The engine’s line converts a clear tactical opportunity into a material advantage, whereas the played move only gives a check without any compensation.

KEY PRINCIPLE

Never miss a hanging piece: Before issuing checks or pursuing tempo, always scan the board for undefended enemy pieces that can be captured with a forcing sequence. Capturing a free piece and ensuring you can recapture any reply often yields a material win that outweighs the value of a check.

Master Lens

Hikaru (Black) out‑maneuvered his opponent in a Four Knights Game, turning a solid opening into a powerful middlegame attack and then a winning endgame. By exploiting open files with his rooks, keeping the bishop pair active, and finally converting a material advantage, he secured a win.

What The GM Did Well By Phase

Opening

Black chose the Four Knights setup and immediately fianchettoed the king’s bishop with **4...g6** and **5...Bg7**, giving the bishop a long diagonal that pressures White’s centre. He then moved the king to **9...Kh7**, sidestepping any back‑rank threats while keeping the king safe. The early pawn break **12...f5** opened lines for the pieces and forced White’s pawn structure to become fragmented, showing how a well‑timed pawn advance can create attacking chances.

Middlegame

After the centre opened, Black’s rooks entered the enemy camp via the c‑ and d‑files: **28...Rdf8**, **29...Rc7**, **30...Rc3**, and later **31...Rf7**. These moves placed the rooks on active squares where they could attack White’s pawns and the bishop on e5. Meanwhile the bishop pair (the dark‑squared bishop on g7 and the light‑squared bishop that later moved to **41...Bf8**) controlled key diagonals, limiting White’s king safety. Black also created a passed pawn on the b‑file after **46.Rxb5**, demonstrating how a passed pawn can become a decisive endgame weapon.

Endgame

In the final phase Black had a clear winning tactic but missed it with **44...Rd3+**. The stronger move **44...Rxe5** would have captured the hanging White bishop on e5, then after **45.Rxe5 Rxe5** Black would be up a rook for a bishop (+2 material). The lesson is to always look for undefended pieces before delivering checks. After correcting the oversight, Black used his rooks on the seventh rank (**48...Rh3**, **49...Rg2**) and the passed b‑pawn to force White’s resignation, illustrating the power of active rooks and passed pawns in the endgame.
