Driving a coup(e)

Playing bridge online at OKbridge, Xwing was dealt:
A Q 8 5 K 10 8 7 6 Q 8 10 3.

Play along with her.

You pass, left-hand opponent opens 2, partner bids 3 and RHO raises to 3. Over to you.

You can make a case for a responsive double, assuming you play them in this sequence, but 3 has a lot going for it in that you have five of them and that is what Xwing bid.

It went all pass and West fired out the J. Here is what you see (hands rotated for convenience):

K 7 4
9 2
5 4
A K J 7 6 2
===
A Q 8 5
K 10 8 7 6
Q 8
10 3

Declarer won the K in dummy and advanced the 9, low, low and won by West with the jack. West now led the K and another to East's ace. East exited with a low spade.

South played the 8 which held the trick! She crossed to the A and led another heart, 4, 7 and won by West with the ace. West exited with the J, a club from dummy, East followed with the 10 and South ruffed it.

At this point she was pretty sure hearts were originally 4-2, so she cashed the A Q and led a club to the king. At trick 12, she was in dummy with the K 10 sitting over East's Q 5 -- nicely done!

Here are all four hands:

K 7 4
9 2
5 4
A K J 7 6 2
J 6 10 9 3 2
A J Q 5 4 3
K J 9 7 6 3 A 10 2
8 5 4 Q 9
A Q 8 5
K 10 8 7 6
Q 8
10 3

Making plus 140 was good for a 4.81-IMP pickup for Xwing. Her maneuver is called a trump coup.

Correction: Do you see what West could have done? Instead of leading a third round of diamonds, she could have played a club. Xwing can guess to rise with the K, and run clubs (discarding losers), but she has three trumps and East only has two, so the coup doesn't work.

A total of 136 pairs played this board, and you can see all the results here.
