Assess your matchpoint score

This hand genuinely surprised me with the matchpoint scores.

I think opps had issues about what the second double was and we quickly wrapped up -300.

 

What % of the matchpoints do you think this was worth, regional swiss pairs, standard fairly mixed.

About 70% assuming that of NS pairs:

  • 15% Reach a partscore.
  • 10% Fail to double a sacrifice.
  • 5% Go down in a slam.

I would think -300 would score very well, maybe 80-90%, and a cold top would not surprise me. NS have misbid badly. Par should be -650 or so for 4M N-S. 5x will be -800. A few NS might bid a slam, but they also might make it.

 

I could be overestimating the field though.

 

edit: in fact, now that I think about it, a matchpoint fix is probably the reason this hand made the forum.

Nobody managed that although 1 NS got a complete bottom for 2N-1 !

 

Standard was very mixed, quite a few welsh internationals to people playing their first serious event.

Nobody managed to go off in 4, then? In a mixed field I would have thought that was quite possible, eg lead ruffed, to A and a losing finesse, followed by another , ruffed. Now the last trump drawn, AK cashed, and so long as West doesn't ruff J declarer will go off.

No, 2N-1 was the only minus, I suspect the field was up to either playing AKJ before drawing the last trump or playing AKx either of which will make 4. I have the frequencies and will publish them later.

I would think it's a very poor score. Opps have enough s to sacrifice much higher than 3-level. After a 1 opening many roads lead to us making game or them defending higher.

We were EW in the land of the weak no trump, so 1N-X was going to be a pretty common start.

I suppose. But, if it is the land of weak NT, shouldn't it also be the land of defenses to weak NT?

 

The most common defense to weak 1NT (that applies here) is double for penalties. I think most E players will try escaping to ; how they do that and what S does will vary. There will be a fair few 2 transfer starts; some XX showing a single suiter and being left in by a misunderstanding, and other gratuitous disasters. Overall I think a lot of NS pairs may run into trouble: after the start

1N-X-2-?

not all will have discussed whether doubles are for takeout here (I think they should be, as then S can show values with no clear direction), and some S hands might bid 2 - at which stage N says "I've got almost a minimum double with 3-card support, so I'll pass".

 

You're then booked for a bad score conceding 300 in 3X as E/W.

 

Of course, I think S should do something stronger than 2 - 3 would be my choice over 2 - and then you probably find some game or another. Forgive me if I'm wrong, but doesn't 6 have play even on a lead?

 

(edit: 7 makes double-dummy unless my analysis is incorrect, but it needs the break and the trump guess)

I think many people play 1N-X-2-X as pens.

 

6 would earn you all the matchpoints.

 

Frequencies as follows.

 

-100: 1 (2N-1)

100: 1 (3-2)

150: 1 (4-3)

200: 3 (spade partial)

230: 2

260: 3

300: 1

650: 1

680: 2

710: 10

800: 5

 

So we got 62% for -300.

What did you expect?

 

A bit better than that (when we played the board which was in the final match as our last board, we were getting less than 60 according to the bridgemates, I was slightly surprised when I looked the board up today and found it had climbed to 62), I was surprised how many people played partscores or didn't double 3/4.

We are obv biased by you posting the hand in this manner, it was clear you got much lower than expected, I cannot expect estimating anything other than top on this board which means 90-100 %. I do not live in a country where wk NT is standard though, I guess thats what made people stop in partscore.
