best line in grand

[whereagles]

After some ridiculous bidding, you land on your feet in a reasonably decent grand slam

 

[hv=pc=n&s=st3hkqj43dakq6ca5&n=sak7642ha72dj3cqt]133|200|South plays 7H. Lead: spade 9[/hv]

West leads 9 spades (dummy's first suit bid) after some thought (not much time though).

 

There seems to be two lines:

 

1. Disc a club on a diamond and ruff a club.

2. Try to setup spades, regardless of the lead warnings.

 

You can also try for a squeeze, but for that you'd need RHO to have KJ of clubs (not very likely).

 

How do you evaluate your chances and how would you play it?

 

Thx in advance :)

Is this one of those cases where you took the obvious line (1) and your partner yelled at you when diamonds were 5-2?

[manudude03]

I'd play for diamonds 4-3 too. On a minor note, it is extremely unlikely that there would be a squeeze against RHO, your club threat is the 5.

[whereagles]

I thought the club 10 was with south, sorry. Anyway, forget that line. It's inferior no matter what lol.

 

As to whether (1) is obvious, well that's what I want to find out :)

In my non-expert opinion, developing spades requires trumps to behave, and it's more likely diamonds behave.

No it doesn't, J♦ is an entry so you can draw 4 rounds then ruff a spade.

 

9♠ is an odd lead, I wouldn't read too much into it, but why hasn't he led a trump ? I'd need to see the auction to know what you've shown/denied and what the leader might be afraid of in the other suits.

I'm being dense, but what do you mean? You need an entry to enjoy the spades, right?

And J♦ is that entry.

Take the ♥KQ first and you also beat some 4-1 spade breaks.

If I were West I would be very reluctant to lead a stiff 9 of spades. It looks like a strong inference that spades are 3-2.

Indeed - I was also trying to interpret the "lead warnings" referred to in the OP. Against a small slam it would be different, of course, since West might be looking for a ruff, but that is not typically the case against a grand! He might be looking to give a ruff, of course, but in that case the spades are presumably 5-0 and there is nothing you can do about it.

Auction went

 

South North

1♥ 1♠

3♦ 4NT

5♦ 5NT

7♦ 7♥

pass

 

4NT was RKCB for diamonds.

5NT was a general grand slam try.

7♦ was "I got 9 tricks in the reds, 1 ruff, 2 aces. That's 12 on top and I'm sure I can conjure up a 13th."

7♥ was "oops.. things got out of hand.. hope this makes"

 

I told you bidding was ridiculous :)

 

And.. spades are not 5-0 of course :)

[Cyberyeti]

On that auction, particularly if I have a stiff heart and the K♣, the J or both, I probably lead a spade regardless of the spade length. It's also possible a spade lead will cause comms issues if declarer has a stiff spade which is not that unlikely.

 

A singleton spade alongside any 3/4 card heart holding would be very unattractive to lead against a grand for most people.

 

Is Q98, x, xxxxx, Kxxx plausible ? I'd certainly lead 9♠ from that.

[gnasher]

Ignoring any inferences from the lead:

 

(1) Play diamonds immediately: works when diamonds are 4-3; or LHO has two diamonds, ♣K and the spade length.

 

(2) Draw two trumps from hand and then play spades: works when spades are 3-2; or the same hand has four spades and three trumps.

 

In each case the secondary chance is only going to be worth a few percent, so we can probably just compare the two main chances. 4-3 is 62%, and 3-2 is 68%, so I'm sure line (2) is better a priori.

 

What can we infer from the lead? It will probably never be a singleton, but will quite often be a "cunning" play from a 4-card holding.

 

However, we don't have all the information we're entitled to. What did RHO play on the first spade?

Exactly, I was assuming RHO played small as we weren't told he didn't, and it's an odd lead from QJ9x.

I'd go for the ruffing out ♠ line but the suggested lines are close:

• ♠K, ♥AKQJ, ♠A, ruff a ♠ depends on a 3-2 break. 68%? or 71%, now that the 5-0 break is eliminated? or worse because of the lead?
• Wanoff's line: ♥KQ and if they break then then ♠AK is even better :)
• ♠K, ♦JQK ♣A, ♣ ruff seems to depend on a 4-3 break (62%). However you have a slight extra chance. If LHO has only 2♦, you can over-ruff him, cash ♣A and run your red-suits, squeezing him, if he has ♣K and has led from a 3 or 4 card ♠ holding,

[whereagles]

Thx all.

 

I was south and I played KQ♥. I reasoned if trumps are 3-2, I could try and ruff out the spades completely. This works even with spades 4-1 if the player with a singleton happens to have only 2 spades.

 

In practice RHO discarded in the 2nd trump, so I was left with the chance of spades 3-2. Played to the A♥, then got back to hand with a diamond to pull last trump and ruffed a spade. The ♦J served as entry to the established spades.

 

I'm glad I followed this line because diamonds proved to be 5-2, but I wasn't sure it was the best chance. In any case both lines are close, so any of them would be a good plan.

 

Cheers!

 

P.S. east's spade on trick 1 was a non-descript 5.

[Mbodell]

I think at the table I'd cash ♠A, ♥A, ♥K, ♦J, ♦A, ♦K (pitch ♣), ♣A, ♣ ruff, ♠K, ♠ ruff (high if trump were 3-2, low if not).

 

This requires diamonds 4-3 or short diamonds with short hearts and spades no worse than 3-2 (unless again short spades with short hearts). But looks like pulling trump and then going after spades is probably best.
