- Neglecting development — Extra pawn moves in the opening are tempting, especially when you "know the moves". Developing a piece each turn is the simple correction.
- Ignoring the kingside attack — In sharp Sicilian lines, White typically castles long and pushes the h-pawn. Without your own counterplay on the queenside or in the centre, White's attack lands first.
