North opened 1. After East's Pass, what should South bid?

Although some players like to bash with 3NT, I think it is better to go slowly and scientifically with 1.

I don't see the need to insist on 3NT without investigating.

Over South's 1, West bids 2.

At the table, North bid 3 (this is not a "Western Cue-Bid" per se--it just shows a good hand).

East bid 4, and South was now interested in slam. He chose to bid 5NT to say "partner, pick-a-slam."

North picked diamonds, so this was the auction to the small slam:

West	North	East	South
--	1	Pass	1
2	3	4	5NT
Pass	6	All Pass

How should South play on the K lead?

Other than the club suit, South looks to be in good shape. At the table, he won the A and played a club to trick two, intending to finesse. This is fairly safe, since West would likely have led a singleton club had he held only one. When the club was played from hand, West produced the king. This is a case of good news bad news. The good news: The K is onside. The bad news: It looks as if East might have started with J982, which could mean 2 club losers for declarer.

After winning the A, what should declarer do next? It looks like time to start trumps and two high ones from dummy show that West started with 10xxx. East throws a spade on the second round of diamonds.

Now what?

It seems that West started with 6 spades and 4 diamonds and 2-1 in hearts/clubs. Can you see the trouble East will be in if he started with Jxxx in both clubs and hearts? Declarer should cross to the K to ruff his spade loser in dummy. Then play dummy's last high trump and come to the Q (all following low) to leave this position:

-- A 10 -- Q 10 6
-- 5 A 7 5 4

Declarer plays the A to draw West's last trump. What should he throw from dummy?

Anything should work.

At this point, you expect East is down to Jx and J9x.

Let's say you throw a low club from dummy.

What will East keep?

He can't throw a heart, because that will set up dummy's 10.

So, he throws a club.

Now, he is down to Jx in each suit.

You cross to dummy with either a club or heart and then throw East in to give dummy the last two tricks.

This was the full deal:

Let's follow the play with all cards in view. Declarer won the spade lead and played a club to West's king and dummy's ace. Next came two high trumps from dummy. Then came the K to ruff a spade. Dummy's last trump was cashed and declarer came to the Q to draw the last trump. East did not enjoy the process at all. No matter what he keeps, declarer can always throw him in at trick 11 to provide dummy with the last two tricks. A well earned +1370 for North-South.
