Ogust is a conventional 2NT response to a weak two bid or weak jump overcall. It is an artificial strong bid, showing 15+ points with interest in game.

Responses:

• 3♣ shows a "minimal" hand with a "poor" suit;

• 3♦ shows a "minimal" hand with a "good" suit;

• 3♥ shows a "maximal" hand with a "poor" suit;

• 3♠ shows a "maximal" hand with a "good" suit;

• 3NT shows a "solid" suit AKQ.

After the intervention, the convention is off (apart from double).
