Your moves Opponent moves

Found 4 crucial moments (2 blunders, 2 missed opportunitys).

Moment 1 — Missed Opportunity MINOR ↗

Missed Trapped Piece

FEN: r1b2rk1/pp2ppbp/5np1/3qn1N1/3N4/1P3P2/P1P3PP/R1BQ1RK1 b - - 0 13

You Played: Nxf3+
You Could Have Played: h6
Eval Swing: -258 cp
Variation: h6 f4 hxg5 fxe5

You could have played: h6 f4 hxg5 fxe5

Coach Explanation

You had a chance to trap the knight on g5 with h6. If white responds with f4, then hxg5 and finally fxe5 wins material. This line leaves white with a strategically weakened pawn structure.

Moment 2 — Missed Opportunity MINOR ↗

Missed Trapped Piece

FEN: r1b2rk1/pp2ppbp/5np1/3q2N1/3N4/1P3P2/P1P4P/R1BQ1RK1 b - - 0 14

You Played: Nh5
You Could Have Played: h6
Eval Swing: -215 cp
Variation: h6 c4 Qd8 Nb5

You could have played: h6 c4 Qd8 Nb5

Coach Explanation

You had a chance to play h6! This move initiates a favorable sequence. If White responds with c4, you can then play Qd8, followed by Nb5. This sequence traps the Knight on g5.

Moment 3 — Blunder CRITICAL ↗

Hanging Piece

FEN: r1b2rk1/pp2ppbp/6p1/3q2Nn/2PN4/1P3P2/P6P/R1BQ1RK1 b - - 0 15

You Played: Qxg5+
Engine Best: Qxd4+
Eval Swing: -962 cp
Variation: Qxd4+ Qxd4 Bxd4+ Kg2

CRITICAL: Your move allowed the opponent to immediately capture your Black Queen on g5.

Refutation: Bxg5 Rd8 Be3 e5

Coach Explanation

BLUNDER: You hung your Queen. The opponent can simply take it with Bxg5. After Bxg5, the opponent can play Rd8 and Be3, consolidating their position.

Qxd4+ is superior because after Qxd4+ Qxd4 Bxd4+ Kg2 you will be down material, but still in the game.

Moment 4 — Blunder MAJOR ↗

Losing Exchange

FEN: 3r1rk1/pp2Bp1p/6p1/7n/2Pb4/1P3P1b/P6P/R2QR2K b - - 1 19

Variation: Nf4 Qd2

CRITICAL: Your move allowed the opponent to immediately capture your Black Rook on d8.

Refutation: Bxd8

Coach Explanation

BLUNDER: You hung your Rook. The opponent can simply take it with Bxd8.

Nf4 is superior because it develops a piece and creates a threat. The engine line is Nf4 Qd2.

Recurring Patterns

Across the 23 analyzed games, erivera90 struggles consistently with hanging pawns, which occur far more often than any other type of error. While missed opportunities were absent in the most recent games, blunders continue to be a problem. Specifically, this game strongly reinforces a weakness in piece safety, with both 'Hanging Queen' and 'Hanging Piece' blunders contributing to material loss. This focus on hanging pieces departs somewhat from the more frequent positional errors and missed tactical shots seen earlier.
