Cappelletti overcalls after a 1NT opening

Cappelletti overcalls after a 1NT opening are:

Double, which is punitive
2 clubs shows a one suiter with 6+ cards
2 diamonds (Landy convention) with the majors at least 5-4
2 ♥ or 2♠ to show a 2 suiter with a 5 card in the major bid and a 5 cards minor
2NT calling for the minors at least 5-5 (...preferably 6-5)

Don't forget to check who is vulnerable and that your distribution is more important than your HCP. Your honors should be concentrated in the suits signaled.

S	W	N	E

Problem E5477 PASS.. with your dispersed honors your hand is much too defensive to overcall .Everything would change if you had a singleton ♠.

S	W	N	E

Problem E40146 2 ♥An overcall of 2 ♥ or 2 ♠ shows a 2-suiter (5-5) with the major bid and an unnamed minor.

2 ♦ overcall and the following bids.

Partner bids a major depending on his strength. If weak, he bids his weakest major, if necessary the overcaller rectifies.
If he wants to know the overcaller's major, he bids 2NT.: The overcaller bids 3 ♣ for ♥ and 3♦ for ♠ and minimum points.
With maximum points the overcaller bids 3 ♥ for ♠ and 3 ♠ for ♥ ! (Be careful !)

S	W	N	E

Problem E40147 2 ♣ this shows a 1-suiter (6+ cards).

S	W	N	E

Problem E40148 ? bid your longest major.

2NT signalling the minors
2NT shows a hand with 10 or so HCP and, preferably, 6-5 in the minors (the 1NT opener is more likely to have strong minors than majors...) In response to this overcall, Partner bids his best minor.
The DOUBLE : showing a long minor and a major of at least 4 cards. This overcall is much more frequent than the Landy or 2NT. See the corresponding information note.

S	W	N	E

2 NT showing the minors at least 5-5.

S	W	N	E

Problem E40150 2♥ This convention on a 1NT opening shows a a 2-suiter (at least 5-5) with ♥ and an unnamed minor

2 ♦
This is a very efficient and economic overcall promising

at least 5-4 in the majors
and opening points

The bidding after 2 CA:

2 ♥ or 2 ♠ sign off in your longest major
3 ♥ or 3 ♠ game invite in your longest major

S	W	N	E

Problem E1504 2 ♦ to show your 2 major suits

S	W	N	E

3 ♣ to show your long suit and get in the way of the opps. 2 ♣ showing a 1-suiter is possible, but even if the opps do not bid, you'll still end up playing 3♣ from your hand
