Variation: f3 h5
CRITICAL: Your move allowed the opponent to immediately capture your White Rook on h1.
Refutation: Bxh1 f3 O-O Kf2

Coach Explanation

BLUNDER: You hung your Rook. The opponent can simply take it with Bxh1.

f3 is superior because it prevents immediate material loss. After Nf4 Bxh1 f3 O-O Kf2, Black is better but White can castle. After f3 h5, the position is more equal.
