Solutions

1. Love All. Dealer West aaxx

It’s not often partner doubles an enemy grand slam when you are looking at two aces. How do you plan to defend?

It should be clear that partner’s double is directing you to find an unusual lead. As you can see by looking at the full deal the 2 will produce the maximum penalty.

aaxxThe bidding of the East-West pair leaves a lot to be desired! At the table North was not wide awake and after cashing the A (200 points down the drain, celebrated by cashing the A (kissing goodbye to another 200). In the other room your team-mates collected +100 from 6 doubled. If you led the 2 you win 12 IMPs. If you cashed the A first you collect 9 IMPs. If you cashed the }A and then tried the spade ace your gain is 5 IMPs.

2.Love All. Dealer Westaaxx

After West opens with a weak 2 you (North) arrive in 6. East leads the 7. What is your plan?

Your general plan will be to win the opening lead with the A, cash two top spades, unblock the K and cross to dummy with a diamond to discard your losing heart. When West turns out to have the master trump it costs you nothing to ruff a club before conceding a trump trick.Then if the diamonds don’t break you will be able to squeeze East on this layout:aaxxIn the other room the North-South pair were content to stop in 4 and they made 11 tricks for +450. If you would have made your slam you win 11 IMPs. If you went down you lose the same 11 IMPs.

3. E/W Vul. Dealer Southaaxx

South opens 2 (semi-forcing) and rebids 3NT over North’s relay of 2. North raises to 6NT and you have to find a lead.

I hope you selected the Q! The full deal was:

aaxx

Your other pair found their heart fit but did not advance beyond game so you win 11 IMPs if you led a club. Otherwise you lose 11 IMPs.

4. Love All. Dealer North

aaxx

What do you lead?

Only a heart will do! aaxxYour team-mates made 6 in the other room so you win 14 IMPs if you led a heart, otherwise it’s a flat board.You may berate your partner for failing to double 3 but in real life the World Champion sitting East led a heart anyway

5. E/W Vul. Dealer South.aaxxYour opening lead?

Trying to cash the A will prove to be expensive!

aaxx

In the other room your pair collected only +500 from 6 doubled so you gain 12 IMPs if you led a spade. If you tried the A you concede -1630 and 15 IMPs.

6. E/W Vul. Dealer SouthaaxxWhat do you bid?

If you think partner is showing a strong balanced hand then there is a lot to be said for passing.aaxxAlmost any defence will net +1100. In the other room North-South recorded +180 so you win 14 IMPs by passing. If you removed the double to 2 then you lose 2 IMPs.

On this simple set of six boards you could be anywhere between +61 and -12 IMPs. How did you fare?
