The bottom lines
-
A 7 card
suit headed by the AK is huge, it is even huger when partner shows a balanced 18-19 points and you should be looking for the grand
if all keycards are present.
-
To ask for
the trump queen, bid 5 of the cheapest suit over 5♣/♦
(but not the trump suit which is a sign off).
-
If you
don’t have the trump queen but have an extra trump, then say that you have the
queen.

A 1-level penalty – more than a slam! Board 25 from Monday 16th
I just love doubling the opponents for
penalties, even at the one level. This time we doubled them at the 1-level and
missed a slam! No probblem.

And what happened? One N-S pair bid
to 6NT and made 1020, However 1♠*
went -4 (this was under dispute as one player thought it was -5, but he settled
for -4 to save time) and the 1100 penalty was more than the slam! Most N-S
pairs bid to 3NT with all making with various numbers of overt
The bottom lines
-
Don’t
listen to people who say you should not double 1-level contracts for penalties.
- Of
course most doubles at the 1-level are for take-out, but not after a redouble.

leads the ♠2 to East’s ♠A and East returns the ♠Q to your ♠K. You cash the ♥K
and lead another trump to the ♥A, West discarding.
Review
the bidding and play so far and choose your play in the ♦ suit. Do you finesse against East or West,
or do you expect the ♦Q to
drop?

KQ1075 this is the bidding from the book.
♦ A106 (2) A cue bid.
♣ KJ7
Answer: You continue with drawing trumps, finessing East’s ♥J.
Are you ready to play the ♦ suit? Should you play low to dummy’s ♦K expecting East to hold the ♦Q because of his overcall? Or should you first cash the ♦A and finesse against West, expecting West to have greater length in ♦’s?
There is no need to guess. First you should cash three rounds of ♣’s. When both defenders follow suit you know what to do. East has at least 5 ♠’s, 4 ♥’s and 3 ♣’s. Therefore he can have no more than one ♦. After cashing the ♦A you make the slam, taking the marked finesse against West’s ♦Q.
And what happened at the Pattaya Bridge Club? Four out of 12 bid the slam, two made it and
two made +1. The other 8 contracts were the usual spurious ones such as 3NT, 4♥ and 4♠*(E).
The bottom lines: -
-
When in
search of an elusive queen, don’t commit yourself too early. Look for more
information first and get a (partial) count on the hand.

Declarer discarded two ♦’s and a ♣ from dummy as he drew trumps, and South also threw two ♦’s and a ♣. Declarer then cashed the ♠K and ruffed a ♠. When the ♠Q did not drop declarer tried the ♦ finesse. South won and returned the ♠Q which declarer ruffed. Declarer then tried the ♣ finesse and when that also lost he was one down.
How should West have played the hand?
Although he has many options he has an easy 100% play for the contract:
He takes the first ♠, draws trumps and then leads a ♣ to dummy’s ♣9 (if North covered with the ♣10 or ♣J then dummy plays the ♣Q).
When South wins, he must concede the slam, any return gives declarer
a free finesse and his 12th t
And what happened at the Pattaya Bridge Club? 7NT-2, 7NT-1, 6NT+1, 6NT=(twice), 6♥=(three times), 6♥-1(3 times), 4♥+2 and 4♥+1.

Opening
1NT with a singleton (A or K) tells you partner your values immediately and in
this case facilitated a good penalty.

Quiz Answers
Hand A: (a) 1NT.
Of course you can open 1♦ if you prefer.
(b) I
don’t know. I guess that 2♣ is the lesser of
the evils. 1NT is an underbid and 2NT is an overbid as is 3♣.
Hand C: (a) 1NT. Of course you can open 1♣
or 1♦ if you prefer.
(b) I
don’t know. 1NT is an underbid and 2NT is an overbid. If you opened 1♣ then a reverse into 2♦ (or 2♥)
would show the values but imply a 5-card ♣
suit. If you opened 1♦ then 2♣ or 2♥
are possible but both of these imply a 5-card ♦ suit.
