I have given two bidding sequences for this doomed attempt at slam, though they began with substantially the same first three bids that should have defined the hand. If you're playing 15-17 one no openings and 20-21 two no openings, as seems to be common these days, then the opening bidder, with a jump rebid of 2 no, cannot have more than 19 hcp's. And the responder has 13.
