Here's a hand I watched from the Belarus / Poland match today (Board 8):

Scoring: IMP


The Poles both took conservative positions and stopped at 2. Belarus got to 4 which made after a high club lead. Declarer can set up diamonds and South can't get in enough to develop a spade trick for the defense.

A few specs commented that a low club lead will beat 4 since South now has three entries to attack spades, but is this really the case?

Also - can you suggest rearranging some cards to give the other side a fighting chance?

Declarer can strip squeeze North.

After 2 lead to 9 and J, declarer wins the spade switch somewhere, cashes his trumps, plays a diamond to the ace, and endplays North with a club.

If North leads 10 to J, trying to keep a club entry to the South hand, declarer eliminates South's clubs first: win the spade in dummy, ruff a club, heart to the 10, ruff a club, cash trumps, etc.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

I don't follow Andy. The strip squeeze idea is possible, but how are you managing your entries and how are you going to time things?

Club lead to south, spade through won in the east. Club ruff. Heart to ten. Club ruff.

Pull trumps, diamond to ace, exit a club pitching a diamond loser. Now north is on lead (south cannot win the fourth club obviously):

Scoring: IMP


North can cash a club (west pitching the last losing diamond) but now he is endplayed.

Of course, this is a rather double-dummy line.

After a low club lead and a spade return, win the SK and ruff a club. Then trump to the T and ruff another club. Draw trumps, diamond to the Ace and endplay North to cash their 2 remaining clubs.

Edit: didn't notoice awm had already said it. I agree it's also pretty double dummy..but hey, a low club lead from the start is pretty double dummy already ain't it!

That's a strange question. I described the first nine tricks in their entirety. The remaining four tricks will involve North cashing two club winners followed by me scoring two spade tricks.

As I said, the line described by awm and andy_h, where declarer ruffs two clubs in hand, is necessary only after 10 lead. On a low club lead there's no need for all this messing about.

There's a lot of interesting variations. Here's the one I like:

1. Low club, NINE, J, x (blocks the suit).
2. Spade, won in hand.
3. Diamond up, ducking the King

From here, I think you can run the trumps, and strip squeeze North as others have described. There are some continuations where you can cal play a loser on loser and rectify the count for a black squeeze as well.

In many variations, note that it doesn't matter where you win the spade trick.

Sorry, I didn't realize you were peeling off all the trump.
