IMPs, 7-board matches
3♣ does not promise extra values, but should be a real suit
3♥ would be artificial and forcing to game
4♣ would be RKCB for clubs
4NT had not been discussed; what do you think it should be?
What call do you make?
At the table I considered 3♥, 3NT, 4♣, 5♣, and 6♣. Any other calls come to mind?
