2NT. You open 1♥ and then rebid 2♥, with nothing else to say. However, your partner has now bid the opponents’ suit. What does it mean? Your partner’s bid is a strong bid – in this kind of auction it does not promise support, but is asking you to describe anything else about your hand, particularly whether you can stop the run of the spade suit. That is, of course, what you can do – although your spades are not strong, they are enough to stop the spade suit, so you bid 2NT and your partner bids 3NT. All East wanted was an assurance that you can stop the spade suit and, with it, you should be able to scrape together nine tricks.
