Opener's response, though, depends on his points and other aspects of his hand.\n\nWhen opener does have a feature in a side suit, and is at or close to 9-11 points, he should bid the suit of the feature. Responder now knows that opener has a good, long diamond suit, and a heart ace or king (responder has the queen).\n\nResponder, with a decent, long spade suit, can invite to game in spades. If opener had no spade support, he could always revert to diamonds, knowing that responder has high points or he would not have bid 2NT to explore further. But here, with good spade support, opener bids on to 4!S."}
