The follow on bids after 2♦ : for the P of the Overcaller

  • If weak, he bids his cheapest major, Overcaller will rectify if necessary
  • If he wants to know Overcaller's major and strength, he bids 2NT (forcing relay)

Problem E9394
2NT relay bid : fit in both majors and good honors. North has to bid his major.
 
 
Follow on bids after 2♦ and 2NT : Overcaller's 2nd bid.
After a NT opening and your 2♦ overcall, if your P bids 2NT, he is probably fitted in both majors and is asking you to choose and indicate the strength of your overcall
  • An overcall minimum in points bid 3♣ for ♥ and 3♦ for ♠
  • An overcall maximum in points bid 3♥ if you have ♠ and 3♠ if you have CO! (Warning!)
  • Your Partner rectifies the bid : he will therefore be Declarer and the 1NT Opener will be seated in front of dummy ...
