Common Mistakes
- Neglecting development — It can feel productive to make extra pawn moves early, but falling behind in piece development is what loses most amateur games — especially in open positions where active pieces find squares fast.
- Overextending the attack — Gambits look like permission to throw everything forward. They aren't — every attacking move should improve a piece. Random checks and threats burn the initiative once they fail to coordinate.
