Can you reconstruct the other 3 hands so that:

1. West can score 7 tricks with CLUBS as trump.
2. East makes no tricks whatsoever.

And, of course, the other 3 players all assist West in his goal by doing their best to make #1 possible.

I will check back every few hours to see if anyone can do it. If you like, you can private message or email me for hints or the solution.

No responses whatsoever will be made to posts which are off-topic. So don;t waste your time. :)

Will post solution (and, of course, source) once someone solves it. And Yes, it does have a solution. :)

Good luck!!

I'm working on it. To state the obvious: the defense's six tricks are three top spades, choosing spades as north's long suit, and three top trumps. I've modeled the hand with west leading AKQJ of spades with east and south void in spades and discarding four diamonds each. West ruffs the fourth spade. West then cashes the 6 of diamonds, north dumps another spade, and east and south drop the 5 and 4. I'm having trouble sequenceing the play from here until the end because I can't cause everyone to discard all the hearts quickly enough.

You are on the right track. but your current thinking cannot work. The 6 tricks N-S take must be in CLUBS - since they have at least 6 of the remaining clubs (and East cannot possess either 4 of them OR any club above the 9, since then he would have to win a Club trick.)

But you have the right idea regarding what must be done - a LOT of discarding. :(

Clarification: I'm not sure that east and south must be void in spades - maybe they are not. I intended to say that, if they are void in spades, they can discard four high diamonds each in the first four tricks, then west's 6 drops the 5 and 4, then the 3 and 2 are high. West can either cash those cards or "draw trumps" as all three players ruff.

Sorry. I misread.

Yes indeed, both EAST and SOUTH are void of Spades. :( Fantastic start! That is the only way East can also get rid of his clubs without winning any tricks.

And yes a LOT of red suit discards are required. That should give you and otehrs the key to solving it.

Good job so far!

I see why you say that, and it's a good hint. "A prioiri" defenders could win only 3 club tricks if I set up the suit like this:

W: 5432
N: AKQ
E: 876
S: J109

OP and the OP of this thread are the same person. I wouldn't bother replying to his thread as he may later edit his post to prove himself correct.

Yes, the hand is the WEST hand.

nigel has submitted the correct solution, but I will hold off until those still working on it have their chance.

I might still see it if you post it in a new thread. I propose that you either post it in the watercooler, or (better) start your own website with book problems plus their solutions, and add a link to it here.

I don't know where he gets them, but they originally came from: http://icanhascheezburger.com/

There's a related site with dogs: http://ihasahotdog.com/
