FEN: rnb1k2r/pppp1ppp/8/4Pq2/3Qn3/2P1BN2/P1P2PPP/R3KB1R w KQkq - 1 9
You Played: O-O-O
Engine Best: Bd3
Eval Swing: -383 cp
Variation: Bd3 Nc6 Qxe4 Qxe4

Coach Explanation

Castling queenside weakens the king's position given the open files and active black pieces while developing the Bishop to d3 supports the e5 pawn, prepares to control the center, and leads to a favorable exchange after Qxe4.

FEN: r1b1k2r/pppp1ppp/8/4P3/8/P2PBN2/n4PPP/3K1B1R w kq - 1 15
You Played: Ng5
Engine Best: Kc2
Eval Swing: -480 cp
Variation: Kc2

Coach Explanation

Ng5 abandons central control and allows Black significant initiative. Kc2 consolidates the King's safety and prepares for a more stable defense despite being down material. You were objectively lost here, but this move might have set a practical trap.

You Played: d5
Engine Best: Kb2
Eval Swing: -326 cp
Variation: Kb2 f6

Coach Explanation

d5 is a mistake because it worsens your already losing position (-326 centipawns). Kb2 is better as it's the engine's top choice, aiming to consolidate defensively despite a poor outlook. You were objectively lost here, but this move might have set a practical trap.
