Occasional partnership, 2/1 with quite a few gadgets but no agreements on slam methods. No discussion about serious/non-serious or last train.
Given the duplication of rounded suit lengths in the two hands the slam didn't have much play.
West: I'd have thought 4♥ showed extras. Why didn't you sign off with the minimum that you held ?
East: Your 3♠ was still unlimited. My hand although a minimum is rich in controls. If I don't co-operate when I have first round ♥ control you might have trouble bidding more when you have no ♥ control yourself. I thought you'd have extras for launching RKC over 4♥.
