This hand occurred in a side game at the Boston Nationals a couple years ago (the hands are the same give or take some spots). I think this is our first Matchpoint defensive problem, where one has to consider overticks just as much as setting the hand.

Being a good partner, you obeyed the double and led a heart. What's your plan now? Be specific. You and partner were playing UDCA.

The play so far doesn't make much sense to me. Does partner hold KJ1096 of hearts and no side entry? In that case, why didn't he overtake the first heart?

I hope that declarer has AK8 854 Axx Qxxx.
Please note: I am interested in boring, bog standard, 2/1.

As close as I can recall, this was the hand and play to the first few tricks.

If declarer has this hand he is cold now. All he need is to play a and cover pd's card as cheap as he can. So u better hope something that will work for you.

I probably played this hand, but it was several years ago, and I don't remember it, so here goes:

You did indeed play this hand (you were East).

Matchpoint play is always harder. Do I play to set the contract, or do I take a safer defensive line to avoid overtricks but that allows this to make. Luckily this one doesn't fall into that kind of decision. Below are my thoughts.

Thanks Bunnygo.... and Whoops. I was looking at the 85 of clubs on the hand display as i typed my answer. My bad... that has no great change on my line of play, but the trick count is obviously changed significantly. Might explain the missing heart five as well...

...
You and partner were playing UDCA.

Well the spots in hearts are troubling. To wit:

- partner has the K (for his double)
- partner has the J (probably for his double, and because declarer should not duck trick 1 if he holds Jxx)
- declarer has the T (with KJT96, partner should overtake the Q)
- ergo partner must have the 5, but then he should play it at trick 1.

So it seems partner has either:

- made an incorrect double, or
- failed to overtake the Q when he should, or
- failed to play the 5 at trick 1.

None of this matters at IMPs, the only thing to do is unblock spades. But at matchpoints, that might give away a trick. So we have to make a decision, with knowledge that partner has already done something odd. Which means we may not be able to rely on his count signals either. I really don't know what is right.

Not sure it's unclear at all. Any trick we give away by unblocking we get back in .

We know with virtual 100% certainty that South has the A. Thus we know with 100% certainty that if we lead we give up a trick. (Singleton A in South doesn't make sense per the bidding.) So if we take the 3rd trick we give it right back to declarer in . Partner MIGHT be able to win that 3rd trick, so I think it's clear to unblock.

I will not put my high spades on the clubs, since I don't see how I can be hurt by not doing so, and it gives declarer too much help.


Doesnt matter which you discard, once you discard he cashes AK and play a to J

Only works if he has 3 diamonds. With Ax, I will endplay him with a small diamond.

edit: and that was the construction I had in mind, but I see your point

I'm now realizing I probably should have presented the defensive problem from partner's point of view at trick one. At the table, my partner thought "great, my hearts will be set up because the holes are filled. With three hearts in dummy no way declarer will not hold up till the third round, and I can overtake the next trick." This is a nice example hand where realizing a quick switch is needed is good B/I defense.


The hand as presented is probably INT+, but it seems that every poster so far has figured it out.

The unblock is interesting, but I am still not seeing why it is so clear at matchpoints. If declarer holds the ten, I hand him an overtrick. This seems particularly important considering inquiry's point that we may already have a leg up on the field by virtue of not leading a diamond.

Edited : It is true that unblocking can cost us a trick, if declarer has AKT + Axx . You need to make your decision, unblocking still superior since you will be losing only to AKT. , with all other spots next to AK declarer can hold u are winning by unblock.

The problem is seriously flawed because partner made such a mistake at trick 1. If you just switch the heart king and queen (and let partner signal a little more clearly) then there is no mistake and the problem is much nicer.

Yes, that is true. It's also true that the more B/I problem would have been partner's at trick one. Sadly, this was the hand. I didn't think to modify it. Next time...
