The Triple
Congratulations to Terje Lie, who achieved the triple last week with
three score of over 60% with three different partners.
DOPI and DEPO Board 17 from Wednesday 8th June
There were loads of slams on Wednesday two weeks ago, and this one had a competitive auction right up to the seven level. Here is an auction demonstrating DOPI (Double 0 Pass 1) or DEPO (Double Even Pass Odd).
Dealer: ♠ K76 Possible Auction
East ♥ KQ1064 West North East South
N-S vul ♦ 1086 - - - 1♦
♣
K4 2♠ 3♥ 3♠ 4NT
5♠ pass (1) pass 5NT (2)
♠ Q109542 N ♠ J83 pass ? (3) ...
♠ A important
missing card.
♥
A92
♦ AQJ754
♣ AQ7
And what happened? 7NT=, 7♥=, 7♦=, 6♠*-7 and 6NT+1.
The bottom lines:
-
DOPI
responses are the same as RKCB – double 0/3, pass 1/4, next bid = 2 without
etc; of course the first two are interchanged if you play 3014 RKCB. Further
bids are the normal steps but there is a problem here with the 5♠ overcall – after partner has passed to show
one keycard does the next step (5NT) ask for kings or the trump queen? It seems
logical to me that 5NT is always the king ask and if 5NT is also the cheapest
bid then 6♣
is the queen ask.
-
DEPO is
different, as there are only two responses (to always allow for asker to go for
the penalty). The responses are Double = odd (1,3) and Pass = even (0,2,4). The
trump king is included in the response but there is no room to indicate the
trump queen.
-
Some
players play DOPI at the five level and DEPO at the six level.
Balancing Board 7 from Friday 17th June

QJ72 2♣ pass pass 2♠ (5)
♦ 4 pass pass (6) 3♣ pass
♣ A43 pass 3♠ (7) all pass
Table B: (5) This is the answer to question B(b). “Borrow”
a king from partner and balance with 2♠.
(6) Note that North should NOT raise here, South is
bidding North’s points. Raising partner here is what I call ‘hanging partner’
for balancing.
(7) This time it’s North in the pass-out seat and
this is the time to bid, not earlier.
And what happened? It looks like some at our
club do not understand balancing: 3♦-1, 2♣-1, 2♦= and 3♠+2 for a clear top.

You are South, declarer in 6♠. West cashed the ♣A and continues with the ♣K which you ruff. East followed to the first
round and discarded a ♦ on the second round. Plan the play.

♦ AQ8
♣ 6
West cashed the ♣A and continued with the ♣K. East followed to the first round and
discarded a ♦
on the second round. When the hand was first played, declarer tried a dummy
reversal. He led a ♥ to dummy, ruffed a ♣, led to the ♦K, and ruffed another ♣. Then he cashed the ♠K and overtook the ♠Q with the ♠A. If trumps broke 3-2, he could draw the last trump with the ♠10 and claim twelve tricks. But when trumps
broke 4-1 he went down. Is there a better line for twelve tricks?
After declarer ruffs the second ♣, he should test the trumps by taking the ♠K and the ♠A. If both defenders follow, South has enough
entries to proceed with the dummy reversal.
When West discards on the second ♠, South should cash the ♥A,K,Q. If ♥’s break 3-3 declarer can draw the last trump
and the 13th ♥ is his 12th trick. As the cards actually lie, East, with the
long ♥
and the missing trump, must follow to the fourth round of ♥’s which declarer ruffs in dummy to make his
slam.
And what happened at the Pattaya bridge club? 4♠=, 3♠+1 twice, 2♠+2, 5♦*-1.

♦ Q85
♣ 10963
(1) Jacoby 2NT
(2) What did you bid with this East hand A in this
week’s quiz? This answer in the article does indeed show the singleton but I
prefer 4♦,
which shows a 2nd 5-card suit (and obviously a singleton or void in
one of the black suits). The rest of the bidding would be the same.
(3) RKCB for ♠’s, the agreed suit.
(4) Three keycards
(5) Trump queen ask
(6) No trump queen. The best responses to the trump
queen ask are:
– no
trump queen: return
to trump suit
–
Trump
queen and one or more outside kings: bid
the cheapest king
–
Trump
queen but no outside king: 5NT
South leads the ♠J against 6♥. Declarer takes the ♠A and should ruff a ♠ at trick two. After South plays the ♥J or ♥Q on the ♥A at tick three, cross to dummy with a ♣ and ruff a third ♠. Then cash the other two ♣’s in dummy, discarding a ♦.
The chances are very good that none of these
will be ruffed. If you survive this far,
play a ♥
from dummy and finesse the ♥10. If North started with three ♥’s then the ♥10 will win. You can draw the last trump and
guess the ♦’s
for an overtrick.
If North follows to the trump lead from dummy
and the ♥10
loses to the ♥Q
with South, then South is end-played, you make the contract safely with no need
to guess in ♦’s.
Bidding Quiz Answers
Hand A: 4♦. This shows a 2nd 5-card suit (and so obviously a black
singleton/void). I prefer this bid showing a possible source of tricks to the
alternative of 3♠ which shows a ♠ singleton/void.
Hand B: (a) pass. Both opponents are
unlimited and it would be very rash to bid this miserable ♠ suit here.
(b) 2♠. You are in the pass-out (balancing seat) and both opponents have shown
very limited values. So “borrow a king” from partner and bid. Partner has
values but nothing to bid.
Bidding Sequence Quiz Answers
C 1♥ pass 2NT pass 2NT is Jacoby 2NT
3♣ 3♣ shows shortage (singleton or void) in ♣’s.
D 1♥ pass 2NT pass 2NT is Jacoby 2NT
4♣ 4♣ is best played as a 2nd 5-card suit (although some do play
it as a void).
