The 1NT response to a one-of-a-suit opener is a “dustbin” bid, a bid for those weak responding hands that have no viable alternative (unable to bid a suit because they lack the strength for a two over- one response). All true - when the opponent on responder’s right is silent. But if he overcalls, things change. Why? If responder passes, opener now gets another bid. The pressure to respond with a measly six or seven points to keep the bidding alive for an 18 or 19 point opener has gone. Your 1NT response becomes a much stronger statement that you wish to declare 1NT. You will have a balanced(ish) 6-9 point hand (usually nearer nine) and, crucially, a stopper in the overcaller’s suit. Partner opens 1 ♥. Right-hand opponent overcalls 1 ♠

What Happened
3NT declared by South was a disaster because of the lack of a spade stopper. West led ♠J through dummy’s ♠K. ♠K lost to ♠A, and ♠Q1074 followed quickly after. ♣A then ♣10 to ♣K ensured down three.

What Should Have Happened
3NT by North - with ♠K guarded - would only fail on a unlikely club lead. The probable ♠7 lead would see declarer beat ♠J with ♠K and cash five hearts and four diamonds (with the aid of a 3-3 split). Game made plus one.
If you remember just one thing...
After an overcall, a 1NT response is genuine, showing a flattish 6-9 points and a stopper in the overcaller’s suit.
