Bidding Over a 1 NT Opening by Matthias Huberschwiller

A: 2♠ - You need to overcall, showing your good six-card Spade suit.

Some partnerships play another bid, like a Multi 2♦, to show a 6-card major. Be sure to discuss it with your partner.

Your result so far:

A: Pass - With a balanced hand over a balanced 1NT, it's not a good idea to try and find a contract. Your defensive chances are good.

It's better to defeat their 1NT than to play in a 7-card fit and go down, right?

Your result so far:

A: 2♣ - With at least 5-4 shape in the majors, you can use the Landy convention. You are showing both majors with overcalling values.

If you were to bid 2♠, and your partner had four Hearts and one Spade, how would you get to the right contract?

Your result so far:

A: 2♥ - Your partner has bid Landy, showing at least 5-4 in the majors.

You are weak, but with Heart support, you need to bid 2♥. Passing is not an option. Your partner does not have Clubs.

Your result so far:

A: 2♦ - This is tricky. You know you have a major fit, but you don't know where. If your partner has five Hearts, you need to play in Hearts. If he has five Spades, you need to play in Spades.

You don't need to guess. There is a way to ask. The 2♦ bid says "partner, bid your longest major".
