fabianocaruana vs IlanSchnaider

White responded 53.Kg3, moving the king from h2 to g3. This steps the king away from the back‑rank pawn on g2 that is under attack by the black rook on c2, and brings the king closer to the centre and the pawn majority on the kingside. Black's only immediate threat remains ...g2, while White still threatens the pawn advance f7.

Kg3 is an excellent practical move because it neutralises the back‑rank danger and improves king activity in an endgame where the king becomes a fighting piece. The engine’s top suggestion 53.h4 creates a passed pawn, but Kg3 already solves the most urgent defensive problem and keeps the position solid. A move that ignored the rook threat would have allowed ...Rxg2+, losing material.

Activate the king in the endgame: When the opponent threatens a pawn, bring your king forward to both defend and create new threats.

White played 78.Rb5, shifting the rook from f5 to b5. This abandons the immediate tactical shot on the black pawn on f6. The engine’s line shows the winning move 78.Raxf6+!, where the rook on a6 captures the pawn on f6 with check, winning material and forcing the black king into a vulnerable position.

Raxf6+ is superior because it exploits the undefended black pawn on f6 with a checking capture, gaining a pawn and maintaining the attack. By playing Rb5, White loses the tempo and allows Black to consolidate, missing a clear winning opportunity. The engine’s continuation after Rb5 gives Black time to defend, whereas Raxf6+ leads to a decisive material gain.

Never give up a forcing capture: When a piece can be taken with check, seize it immediately; otherwise you risk losing the initiative.

White delivered 83.Rf5+, checking the black king on h5 with the rook from f6. The move forces the king to move but does not create any new threats; Black can simply step to g6 or block with ...Kg4, keeping the position balanced. The engine prefers 83.g4+!, a pawn check that drives the black king onto h4, where it becomes exposed to further decisive attacks.

The pawn check g4+ is stronger because it forces the black king onto a more vulnerable square (h4) and opens lines for White’s rook and king to infiltrate. Rf5+ allows the king to stay relatively safe and gives Black chances to coordinate his rook on e1 with the pawn on e5. By choosing the pawn check, White maximises king exposure and paves the way for a winning attack.

Choose the checking move that restricts the opponent’s king: A check that drives the king into a weaker square is often more powerful than a simple rook check.

White played 87.f4, pushing the pawn from f3 to f4. This move does not address the immediate danger that Black’s rook on e2 poses to the white pawn on e5, nor does it create any new threats. The engine’s optimal continuation is 87.Rd7+!, delivering a check that forces the black king to move and leaves the e5 pawn defended while keeping the rook active.

Rd7+ is superior because it attacks the black king directly, forcing a defensive response and maintaining pressure on the e5 pawn. After Rd7+, White can later capture the e5 pawn or win the rook on e2. The pawn push f4 simply wastes a tempo and allows Black to continue the attack on e5, potentially winning material.

Prioritise defending or counter‑attacking threatened material: When an opponent threatens a pawn, either defend it or create a forcing move; idle pawn pushes that ignore the threat lose momentum.
