In yesterday's tournament, my opponent surprised me with the Two Knights Defence, which led to a very sharp middlegame.

The board adopted a Pac-Man defence to counter the hostile takeover attempt.

Several companies adopted Pac-Man defences when faced with hostile takeover bids, turning the tables on their attackers.

As the old proverb goes, the best defence is attack, so the coach urged his team to press forward.

When negotiating with the competitors, she insisted that attack is the best form of defence and proposed an aggressive marketing campaign.
