FEN: 8/6K1/2k5/p4P2/8/8/8/8 b - - 0 51
You Played: Kd6
Engine Best: a4
Eval Swing: -3540 cp

Coach Explanation

King movement to d6 is a mistake because it allows the white king to control key squares and advance the pawn, leading to promotion. a4 is better because it initiates pawn advancement to disrupt white's pawn structure, creating counterplay and prolonging the game.
