The auction

N :18hp and 36zp, more than enough to open 1

S : 7hp, so answer is 1

W : 14hp, no  5 card  : pass

N : shows his 5 card  w/ 2♠. Not 1♠ because this would mean 20+. Now (s)he limits the hand till 19hp.

S wants to show that (s)he has a maximum of 6-7hp because game is still possible. (s)He bids 2NT, denying a fit in spades.

N : accepts the invitation and raises to 3NT.

Playing

As long as West does not lead diamonds the contract is made : eg.   2 for   J. Then K for A. West switches to diamonds but is too late. S makes 3♠,1 , 1 and 4  .

Turnhout

The auction

E : very unbalanced and so count the zarponits : 35zp (with 14hp) , so E opens 1

S and N always pass

W : 11hp,  balanced, so 2

E : is interested in clubs but first asks the amount of cards in diamonds with step 3 (=2 )

W : the answer is step 2 (3 -2341 ) for 3 cards

E :JNB =  3  asks for length of clubs

W : 3 =step 2 (4321) , for also 3 cards clubs

E : because 3NT would be an endbid , he asks about strength with 4

W :4 is step 2 meaning 11-12hp

E : 4:NT asking for aces

W : 5   =1 or 4   

E can not stop anymore at 5 and risks a 6


Playing

E was lucky when S led with J . For K .E collected A and Q of spades and could discard   8. Then J for Q and A. When E continus with 10  S took K and played A, trumped with 7. Then E played  2 to collect S's last trump. Arriving in W with 6 he now played  Q ,  K, trump. Via Q he got back in W to play J and discard a diamond. E makes 3♠, 1 , 3 and 5  . Contract, thanks to a happy lead.

N : 33zp, 1

S : 23zp, GF, 54xx in major, so 1

N : asks which M?

S : step 1=1NT so spades is the 5 card

N : JNB= 2nd suit?

S : 2 =step 3 of remaining suits=BUT because is the last of the remaining suits S must apply the extension technique and tell in the same answer about a possible singleton. Step 1 becomes step 0 and indicates a 5422.

N : JNB 2NT to ask for the strength

S : step1 = 3♣, 8-10hp

N : fits with spades. No need to investigate slem, therefore : 4♠, although 3NT is an alternative. 

N : 11+18+6=35zp, 1

S : 26zp, GF, 6322 in major, so 2

N : 2 =   asks which M?

S : step 2=2NT so hearts is the 6 card

N : JNB=3=  3card suit?

S : 3 =step 2 of remaining suits= which is not the last of the remaining suits and therefore the extension technique is NOT applicable.

N : JNB= 3 to ask for the strength

S : step1 = 3NT,  8-10hp

N : fits with hearts. He knows that S has two doubletons. Slem is near. On the edge. N decides for  4
