Take over for West, who had to leave in a hurry.  Questions:

1. Has anybody made a mistake in the bidding yet?

2. What's up with partner's double?

3. What is your call?

4. If you pass, what do you lead?

{

1. <i>Has anybody made a mistake in the bidding yet?</i>  Yes, West.  With significant
values in both of East's suits, and no defense, West should already have
sacrificed at 5\C; better yet, 6\C.

2. <i>What's up with partner's double?</i>  This is a Lightner double, to improve
chances for setting the contract.  It calls for an unusual lead, in this case,
not \S, \H or \C.  East must be void in diamonds.  This double by a weak hand
is not pure penalty, but asks West to do something sensible.

3. <i>What is your call?</i>  When the opponents voluntarily bid game, they should
have at least 24 HCP.  Since you are looking at 8 HCP, the best you can hope
for from East is two aces or an ace and a king, likely one in each long suit. 
While you can give partner one ruff, it's unlikely he can put you in to get a
second.  Four tricks are almost impossible.  <i>Run!  Run!  Run!</i>

4. <i>If you pass, what do you lead?</i>  Having ruled out two honor tricks plus two
ruffs, you could try for three honor tricks and one ruff.  Lead the \HQ or \CQ.
 You hope the king will appear in dummy, East has the ace, and you can regain
or retain the lead to give East a ruff.  If you hit the jackpot and two rounds
survive in the suit you led, you are not out of the woods yet.  If East has
only a king in the other suit, a fourth trick may have to materialize out of
thin air.

The alternative to this grim prospect is to give East a ruff, and hope East has
something like AKxxx-T8xxx, either way.  East will ruff the diamond and lead
his king.  You will deposit the queen on it, guaranteeing you can win the next
round.  East puts you in and gets the second ruff.

Sacrificing in clubs is by far the better plan.  Look how well your cards fit
with East's aggressive 2NT bid!
