Scoring: IMP


W plays 4. First lead: J. Plan ?

I am posting because I believe I found better solution than the one offered by Martens.

Have fun :P

I can see nothing good here better than the straightforward play A AK KQ discarding a spade ruff a club and exit a diamond. This cannot be correct :/

edit

I thought I could guard against a 3-1 trump break if the T falls by playing K, ruff high, but if south has the long trumps he can overruff, play a diamond to North, and ruff another club. Annoying hand.

If clubs break 4-2 and an opponent has Qxx of hearts you will have no entry back to hand in time to pitch dummy's other losing spade.

Would play A and a club. What happens?
When Senators have had their sport
And sealed the Law by vote,
It little matters what they thought -
We hang for what they wrote.

I know, that's why it cannot be right, but I cannot see anything better, at least keeps some endplay opportunities alive

Some colclusions ..
If LHO has QTx and Jx you can't normally win. They have sure 3 tricks, and you can't establish without drawing trumps and if you draw trumps you don't have a fast entery back.

If RHO has Qxx and xx you normally need a finesse, because of the same establish /draw trumps problem. However if RHO has both AK, then you are still fine without a finesse.

1. J-A-xx
2.x-x-A-x
3.K-x-x-x
4.x-x-- overruff

He needs partner to lead another to beat contract, so if he has both of top diamond honors, he can't get him on lead.

I should probably suggest following line

1. J-A-xx
2. x-x-J-x

It does lose if LHO has singleton Q and JTxx, but it wins on all other 3-1 and 4-2 breaks on which you had a chance.

If are 5-1 most probably you need to establish without losers and get one ruff trick.

I don't think this should be a book hand, unless there is a clearly superior line which i don't see...

Martens' solution is this:

A, A, K, Q and discard spade. Now we have communication to hand to ruff and discard last spade.

This however this loses to:
-QTx and xx with N (because he will ruff, play and another from S will promote Q
-Qxx and xx with S (same reason but S don't need a T)
-Any time one of the opponents have stiff (which Martens doesn't mention at all)

I think the better play is is to win first trick with A and play for finesse. This way we have two entries to hand with A/K.

This only loses to (assuming clubs aren't 5-1)
-QTx in N hand along with Jx of clubs


It also seems to me that my solution will sometimes win if clubs are 5-1 (if Q is onside) while Marten's solution automatically loses to all those layouts.

I guess the plan is to play A and Q if you win ? If yes it's the same as solution from the book. If no, please elaborate :)

Sure, but you don't lose if N has stiff Q along with Jx

Hmm, why did you delete that line? Just correct Jx to JTxx ...
