Overcalls after a 1NT opening Kit Woolsey's convention
Using the Woolsey convention, the main overcalls after a 1NT opening are:
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.
- 2 clubs (Landy convention) with the majors at least 5-4
- 2 diamonds a suit normally with 6 cards
- 2NT calling for the minors with preferably 6-5 (quite rare)
- 2 ♥ or 2♠ with a 5 card major and a minor 4th
- Double showing a long minor and a major of at least 4 cards
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.

Problem E9189 2 COAn overcall of 2 ♥ or 2 ♠ needs a solid 5 card major and a irregular hand. Ideally you should also have a 4 or 5 cards in a 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 !)

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.
