At move 20 you played 20.Nxd8, the white knight on f7 captured the black rook on d8. The capture removed a rook but immediately allowed Black’s other rook from h8 to recapture on d8 (20...Rxd8). The exchange left White down a piece (the knight) and gave Black a clear material edge. The engine’s analysis shows that White actually had a winning tactic: the pawn on b2 could capture the undefended black knight on c3 (20.bxc3), winning a piece outright. By ignoring that, you turned a winning position into a losing one. Threat data confirms Black’s queen was already eyeing the a2 pawn, while White’s own queen, bishop and rook were still active, but the knight on c3 was hanging.

The engine’s move 20.bxc3 exploits the immediate tactical vulnerability of the black knight on c3, which is completely undefended. Capturing it gains a piece (+3) without any compensation for Black. After 20.bxc3, Black’s best reply is 20...Rde8, simply developing the rook, but White remains up material and retains the initiative. In contrast, 20.Nxd8 trades a rook for a knight and then loses the knight back, resulting in a net loss of material. Moreover, the knight capture does nothing to address Black’s queen threat on a2, whereas the pawn capture both wins material and keeps the queen’s pressure under control.

Spot and Exploit Hanging Pieces: Always scan the board for undefended enemy pieces before launching exchanges. Capturing a free piece (the knight on c3) is superior to a superficial rook trade that leaves you down material.
