Overcalls after a 1NT opening Kit Woolsey's convention

Using the Woolsey convention, the main overcalls after a 1NT opening are:
  • 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.

  • 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.
