unrevealing slam


Fluffy

Recommended Posts

Non-expert partner's 4NT over 3 might mean that he has like 3 or 4 small . The auction would call for a trump lead, however opening leader chose a . There are a few reasons why he chose this lead :

  • he has the tripleton trump Q (and possibly not the A, as he might have led this card instead)
  • he has the doubleton trump Q
  • he has at most one trump and does not want to give out the trump position (again I'd say he lacks the A)
  • his is a singleton

I would play A and try either of these (depending on the mood) :

  • a deceptive 10, intending to pitch a on the K next (unlikely to fool expert defenders, but only costs if lead is singleton)
  • play the 9 intending to finesse

I am having a lot of debates on this hand, so please answer the questions.

 

Another one:

 

Switch K and J for A 4 making the suits:

 

K9

KJ107

 

AJ10843

A

 

How do you play trumps after a A lead?

 

 

What about 5-3?

 

K94

A107

 

AJ1083

KJ

I wouldn't be surprised if LHO has underlead Q with the Q on the side. However, putting all my money on that assumption is too risky. So I'll take the Ace and run 9.

 

that makes 0 sense. you're putting all your money on the Q of S instead.

 

if you want to make a better case for rising with the ace, it offers a modest combination of chances option - the trump finesse or ruffing out the Q of D and getting 2 quick pitches if trumps are 3-2. i would say this is not likely enough to upset me if i thought there was a particular reason to play for 1 queen or the other.

 

as it happens, i would always bet on the Q of D being with the leader - something like 70-80% (i'm clueless at bridge maths) at a guess. people like leading from honours versus slams in hopes of building a trick and if he didn't have the queen he could have chosen some similar filth from which to lead, definitely in clubs and most likely in hearts, a la PoRC.

As a general rule, decent players lead aggressively against slams, but there are several caveats here:

 

1. They are leading round to a 2 opener, which makes it less attractive to attack.

 

2. North has not shown a trick source, so it is less likely they need to attack.

 

3. They know we are off a key card, so West is playing partner for, specifically, the diamond king and an ace to get in with. Otherwise, the lead is likely to just be spew.

 

4. If West has the spade queen, the chances of them attacking are lower still - they will try and find partner's ace.

 

Depending on the level of West's expertise, I would be inclined to downgrade the chance he has the Q considerably.

but below 50% phil? note that the bidding never said that 1 keycard was missing, its 3 + responder ones, and he is not very reliable.

 

Well it would seem odds no to bid 5NT in an unlimited auction even for an unreliable player. It would be more likely he would do it with a key card missing. :ph34r:

 

Yes, under 50% if West is VERY good. He will anticipate a random collection in dummy and just try and server the ball into the middle of the court.

 

I've been trawling through a lot of Vanderbilt, Spingold, USBC, Europeans and World Championships, and attacking slams leads are way less common than I previously thought (no quantifiable data yet).

opps are expert, partner is not, lead is 5 (3rd/5th)

 

I am with A and small . If it loses run the 9 from dummy. I dont like playing small because I dont like going down at trick 1 without exploring other options.

 

If the Ace is led I will still finess the RHO's Q because if I was LHO and the bidding was the same I would defo lead my A - it is a gamble but I dont want to be missing AK :)

people leading a small heart off dummy at any point are evidently used to playing against morons. playing to escape losing to the A of H is just abrogating the Queens issue. man up and make a decision.

 

They are and they have. Since declarer's hand is somewhat unknown thanks to partner's inspired bidding, even a non-moronic East has a problem discerning whether declarer has AKQJxxx KJx x Ax or not (a complete minimum).

 

What is he supposed to do with xx Axxx Qxxx xxx? After all, rising ace only works because we lack a Two Club opener.
