You Played: Nf6
Engine Best: Bxb2
Eval Swing: -330 cp
Variation: Bxb2 c3 Bxa1 O-O

Coach Explanation

Development. Nf6 passively develops while ignoring the hanging bishop on c4. Bxb2 immediately attacks, wins material (a pawn), and opens the position for black's pieces while forcing White to react.

You Played: Rad8
Engine Best: Bf5
Eval Swing: -276 cp
Variation: Bf5 g4 Be6 Nxe6
⚠️ CRITICAL: Your move allowed the opponent to immediately capture your Black Bishop on c2.

Coach Explanation

BLUNDER: You hung your Bishop. The opponent can simply take it with Rxc2. Bf5 develops with tempo, attacks the knight on g5, and prepares to exchange for the light squared Bishop to alleviate white's attack.

You Played: Kxf7
Engine Best: Bxc3
Eval Swing: -262 cp
Variation: Bxc3 Nd6 Rd8 Nb7

Coach Explanation

King's move Kxf7 walks into a worse position, worsening the evaluation by -262 centipawns. The engine's move, Bishop's capture Bxc3, exploits the pinned knight on c3 and leads to a better position, as the current evaluation suggests.

You Played: Bxc3
Engine Best: Rxc3
Eval Swing: -401 cp
Variation: Rxc3 Bc4+ Ke8 Rxc3

Coach Explanation

Material loss. Bxc3 loses a rook for a bishop, worsening the already losing position. Rxc3 recaptures the attacking piece with a rook, mitigating material loss and allowing for further simplification into a more defendable endgame with a check.

You Played: h5
Engine Best: Bd4+
Eval Swing: -1065 cp
Variation: Bd4+ Kf1 Rxc1+ Ke2

Coach Explanation

Pawn moves weaken squares. h5 weakens the g5 square and does not create immediate threats, worsening Black's already bad position. Bd4+ immediately attacks the King, forcing it into a passive defense while simultaneously enabling a devastating Rxc1+ that equalizes the game.

FEN: 2r5/p4k2/6p1/1B5p/P5P1/1Pb2P1P/8/2R3K1 b - - 0 28
You Played: hxg4
Engine Best: Bd4+
Eval Swing: -947 cp
Variation: Bd4+ Kf1 Rxc1+ Ke2

Coach Explanation

Pawn grabbing with hxg4 accelerates the loss due to the exposed king and lack of counterplay. Bd4+ forces the king into a checkmating net, immediately winning material and leading to a favorable endgame.

You Played: Kf6
Engine Best: Bd4+
Eval Swing: -632 cp
Variation: Bd4+ Kf1 Rxc1+ Ke2

Coach Explanation

King movement Kf6 weakens the pawn structure and fails to capitalize on the exposed white king. Bd4+ forces the king to move, enables a rook sacrifice, Rxc1+, to reach equality by perpetual check.
