Your moves Opponent moves

Found 4 crucial moments.

Moment 1 — Blunder MAJOR ↗

FEN: r1bqk2r/p2p1pbp/2p1pnp1/6B1/2B1P3/2N2Q2/PPP2PPP/R3K2R b KQkq - 3 9

You Played: O-O
Engine Best: h6
Eval Swing: -354 cp
Variation: h6 Bh4

Refutation: e5 d5 exf6 Bh8

Coach Explanation

Castling was a mistake because it allows e5 followed by d5. After exf6, Bh8 wins material. h6 is better to prevent Bg5 and prepare to develop your pieces.

Moment 2 — Blunder CRITICAL ↗

Positional

FEN: r2q1rk1/p4pbp/b3pnp1/6B1/3pN3/1B4Q1/PPP2PPP/2KR3R b - - 1 14

You Played: Be2
Engine Best: Nxe4
Eval Swing: -994 cp
Variation: Nxe4 Bxd8 Nxg3 Be7

Refutation: Qh4 Nxe4 Bxd8 d3

Coach Explanation

Be2 is a mistake because it hangs the bishop and allows White to force a winning attack. Nxe4 is superior because it wins a pawn and opens the d-file. After Nxe4 Nxe4 Bxd8 Nxg3 Be7 Black is better. If White plays Qh4, White wins the bishop after Qh4 Nxe4 Bxd8 d3

Moment 3 — Blunder MINOR ↗

Trapped Piece

FEN: r2q1rk1/p4pbp/4pnp1/6B1/3pN3/1B4Q1/PPPRbPPP/2K4R b - - 3 15

You Played: d3
Engine Best: Nxe4
Eval Swing: -208 cp
Variation: Nxe4 Bxd8

CRITICAL: Your move allowed the opponent to immediately capture your Black Knight on f6.

Refutation: Nxf6+

Coach Explanation

BLUNDER: You hung your Bishop. The opponent can simply take it with Nxf6+.

TRAPPED PIECE: d3 is a mistake because it ignores the undefended state of your Bishop on e2 and, crucially, hangs your knight. Nxe4 is the superior move. It initiates the sequence: Nxe4 Bxd8 and simplifies into an equal endgame.

Moment 4 — Blunder CRITICAL ↗

Positional

FEN: 3q1rk1/p4pbp/4pnp1/6B1/4N3/3P2Q1/PPB1bPPP/2K4R b - - 0 18

You Played: Qc8
Engine Best: Nxe4
Eval Swing: -798 cp
Variation: Nxe4 dxe4 Qd4 Qc3

CRITICAL: Your move allowed the opponent to immediately capture your Black Knight on f6.

Refutation: Nxf6+ Kh8 Re1 Qa6

Coach Explanation

BLUNDER: You hung your Knight. The opponent can simply take it with Nxf6+.

Qc8 is a mistake because after Nxf6+ Kh8 Re1 Qa6, White is winning.

Nxe4 is superior because after Nxe4 dxe4 Qd4 Qc3, Black has compensation due to activity. You were objectively lost here, but this move might have set a practical trap.

Recurring Patterns

This game strongly reinforces the established pattern of blundering pieces. The most frequent tactical error across all games analyzed continues to be overlooking "Hanging Pawns," but this game deviates slightly by showcasing a higher incidence of "Hanging Piece" errors. The "Hanging Piece" blunder occurred twice in this single game, whereas the player has only committed this blunder ten times across all 20 games. This suggests a potential lapse in piece safety awareness, particularly in this specific game context.
