Matchpoints. System weak NT, 5cM. The 2S rebid is GF promising either 5+C, 4+S or a huge 4144. Playing natural methods, how can East show a strong-slam-interest spade raise here? Perhaps 3D followed by 4S, but that might be passed?
Our intermediate-level opps bid 1C-1H; STOP 1S (the correct way to show a 20-count while preserving bidding space!)-4S; 4NT (simple BW)-5D (one ace); 6S. The grand however is excellent, particularly when the CJ drops in two rounds.
