Black chose 27...Bd4+, delivering a check by moving the bishop from e5 to d4. The move forces White to interpose a piece (e.g., Re3 or Rf2) or move the king, but it does not win material. White still threatens b7, e5, g2 and h3, while Black's threats are limited to b2, e2 and f4. Crucially, White's rook on e2 and queen on b3 remain undefended, but Black also leaves the pawn on f4 untouched, missing a chance to capture it.

Engine analysis shows 27...Rxf4! as the superior continuation. By taking the pawn on f4, Black wins a pawn, creates a direct threat on f2, and opens lines for the rook and queen to infiltrate White's camp. After 27...Rxf4 28.Qxh3, Black retains a material edge and maintains pressure, whereas 27...Bd4+ allows White to block the check and keep the pawn on f4, preserving defensive resources. The bishop check is a superficial forcing move that does not improve the position, while the rook capture converts a static advantage into a concrete material gain.

Prioritize Material Gains Over Checks: A check is only valuable if it wins material or creates a decisive threat. If a simple capture (like Rxf4) wins a pawn and improves your position, it should be preferred over a checking move that merely forces a defensive reply.

Black executed 29...Qxg1+, capturing the white rook on g1 with the queen and delivering check to the white king on h3. The capture removes White's last active rook and forces the king to recapture on h3 (30.Kxh3). After the exchange Black is up the exchange (a rook for a pawn) and retains a dangerous bishop on d4, while White's remaining threats (b7, g4, h3) are insufficient to compensate for the material loss. White's undefended pieces (a5 pawn, b3 queen, e2 pawn, e7 pawn, f4 pawn) remain vulnerable, but Black's own b7 pawn and d6 pawn are the only undefended pieces on his side.

The engine confirms 29...Qxg1+ as the best move because it wins a whole rook, converting a roughly equal middlegame into a winning material advantage. Any alternative, such as moving the queen elsewhere, would leave the rook on g1 alive and give White chances to generate counterplay. By removing the rook, Black eliminates White's primary attacking piece and simplifies the position, making it easier to convert the advantage. The subsequent forced king capture (Kxh3) further isolates the white king and leaves White with only minor pieces to defend.

Exchange When It Wins Material: When you can capture an opponent's piece of higher value (especially a rook) with a piece that is safe after the capture, you should do so. Winning the exchange can be decisive, as demonstrated by Qxg1+ turning a balanced position into a clear win.
