2♦

2♦ is either 8 playing tricks in an unspecified suit or a balanced 23-24 points.

A strong opener, forcing for one round but not to game. Responder bids 2♥ as a relay with any hand; other bids show a good 5+ card suit. Opener then describes their hand, and responder can pass a minimum rebid below game.

4NT

Requests responder to show any ace in their hand by bidding that suit. With no aces, bid 5♣.
