Best line in 3NT

[Trumpace]

You are South and are in 3NT after 1NT - 3NT. Assume E-W are vul. Rubber bridge.

 

West leads the ♣J and you see...

What is the best line for 9 tricks?

[Echognome]

I win the club (either hand really) and duck a diamond. I win the return and then lay down the ♦A and then I go to dummy and lead towards the Q. I haven't considered any squeeze possibilities, but there don't seem to be any at first glance.

I mistakenly wrote 2005 instead of 2006. Source is Frank Stewart Column Jan 17, 2006.

i assume west doesn't have a 4card major suiter, so i take ♣ Q then duck a major,try to duck another major, then throw in ♣ if it isn't 6-0 distribution.

How about finessing in diamonds and then ducking a round. This gives time to find whether either clubs or diamonds is 4-triple-3.

Problem with this line is that, when you duck the second major, East could win and shift to a diamond.

yes ,so i use the word "try to",remain the playing of ♦ suit

Well, technically, there seems to be a good line:

 

1. Duck a diamond.

2. Cash diamond ace.

3. Lead diamond towards the queen.

4. If all this fails, clubs can still be 3-3 :rolleyes:

[Trumpace]

According the Frank stewart the line that should be taken is:

 

Cash ♦A and then duck a diamond (planning to lead toward the ♦Q later).

This works when ever West does not have Kxxx, Kxxxx or Kxxxxx in diamonds and is better than a simple finesse.

 

 

I think ducking a round of diamonds first and then leading toward the ♦A on the second round is better than the suggested line. This way, we will know if diamonds split 5-1 (Kxxxx with West) and we can then try for 3-3 clubs or a major suit squeeze on East in case West holds 4 clubs (haven't worked out in detail, so could be wrong) by playing a low diamond instead of the A on the second round of diamonds and keeping diamond control (we need to duck 3 diamonds and a club for the squeeze to operate).

Well, you are guarding against West specifically 5+=4+ in the minors. In that case, I you can almost certainly endplay him in clubs after stripping his major cards and finally score your ♦Q.
