- Push b2-b4 and then b4-b5 to evict the c6 knight and punch holes in Black's queenside.
- Open the a or b file to allow white rooks to invade the seventh rank.
- Keep the g2 bishop guarding the king to sterilize Black's kingside attempts.
- Win material on the queenside before Black can organize any tangible threats.
