Common Mistakes to Avoid
- Overextending without backup: When playing a gambit, each attacking move should have a purpose. Random checks and threats without coordination can leave your own position exposed once the initiative fades.
- Releasing central tension too early: The tension between the d5 and c4 pawns is a central feature of this opening. Capturing or pushing too early can give your opponent a free hand in the center.
