Back in the 1950’s Nico Gardener and Victor Mollo, two of the great players of that period
published many books.
In their “Card Play Technique” they introduce the chapter on this subject with”Will
you be good enough to cut your own throats“ which is in effect what you are going to make the defenders
do.
This is their first example..The contract is 6 ♠
North ♠ AKxx ♥ KQX
♦ AJx ♣ Kxx
South ♠ xxxxx ♥ Axx
♦ K10x ♣ Ax
You win the Club lead and take two rounds of Spades leaving the Queen out.
They comment that the contract is now safe,which isn’t strictly true. It is provided West hasnt the
Queen of Spades and only two Clubs as they will overruff and lead a Heart leaving you to guess the Diamonds.
If East were to ruff the third Club with the Queen of Spades you simply throw a Diamond and you are home.
The play is as follows: Cash the other top Club and ruff the third. Then cash the three Hearts.
If one of them is ruffed with the Queen whoever has it must now lead a Diamond into the tenace or give a ruff
and discard.
If the Hearts aren’t ruffed you now play a Spade and whoever has the Queen is in the same position.
Finally a classic situation.The contract is again 6 ♠
North ♠ AKxxx ♥ KQX
♦ Ax ♣ xxx
South ♠ Qxxxx ♥ Axx
♦ Kx ♣ AQ9
How are you going to guarantee that you don’t lose two Clubs.
More or less as you did above.Assuming you don’t get a Club lead of course;that would be too easy.
Take out trumps and cash all the red suit winners taking care to finish in Dummy.
Then you lead a Club and cover whatever East plays. Assuming West wins they are helpless.
A Club back into either the AQ or A9 or a red suit to give a ruff and discard.
