Deal 25	♠   ♥   ♦   ♣		WEST   NORTH   EAST   SOUTH 1NT 2♦ 3♦ pass 3♥ pass  BID    North opens 1NT and East overcalls 2♦. What do you say? Dad-burned interfering opponents. You were going to bid a Stayman 2♣ and now you can't. You also don't want to bid either Major with only 4 of them. And you certainly can't bid notrump with no ♦ stopper. Fortunately the overcall has opened a window of opportunity for you. So you cue-bid 3♦. Even if you and partner haven't discussed this it is pretty obvious that you don't really want to play in ♦s, so the most likely action for him is to bid a suit, and a Major suit would have priority. So really, the cue-bid achieves the same purpose as Stayman would have. Partner now bids 3♥. What do you say?
