{

Opener has 12 HCP and a balanced hand. 

Responder has 11 HCP and four cards in both hearts and spades and so uses
Stayman for a game try. 

Opener has less than four cards in both majors and so gives the negative
response. 

Responder then re-bids NT as there is no major suit fit. 

Responder cannot be certain of game, and so bids NT at the invitational 2
level. 

Opener declines the invitation to game by passing.

Opener has 13 HCP and a balanced hand.

With a maximum of 23 HCP between the two hands there is no game available. 

Stayman would only confuse partner and possibly lead to bidding too high.

Opener has four cards in spades and so bids spades at the two level. 

With 12 HCP, responder invites game with a bid of 3. With a good looking 13,
opener bids the game. 

This bidding is not wrong, and more often than not the game will be there. But
this time the cards don’t sit well for declarer and it should be one down.}

{

An unusual case where you can use Stayman even though there’s no game on. 

South opens 1NT. With 7 HCP North knows there’s no game. 

But he has five spades and four hearts. A weak take out into spades will skip
the chance that partner has four hearts. 

So North inquires with Stayman. 

Partner shows four hearts and North passes to keep it low. 

If partner had shown 4 spades, North would have passed. 

(What if partner denied four of either major? North bids 2\S showing a weak
hand with five spades (and four hearts) a “delayed” weak take out. Opener must
recognise this sequence and pass.)}
