Too many 2NT contracts are going down

[phil_20686]

I think the arguments brought forth by Frances are exactly right. Drawing these conclusions from this data is very foolish.

 

Yes. The conclusion to draw is that people raise 2N to 3N very aggressively. Therefore when they pass they have a truly terrible hand.

 

It has been accepted wisdom that responder cannot evaluate his hand very well, and when he has any shape at all, like xx xxx Qxxxx xxx he should raise a 20-22 NT to game, because if partner has the right cards can have ten tricks, and only 5 when he has the wrong ones. 8 exactly is rare and that is the only time it costs to raise realistically. No one cares about 3 imps.

 

Given this, it is entirely possible that raising the HCP for a 2NT bid will make the problem worse, as partner will raise yet more aggressively.

2NT is a horrible contract; 2NT with all the points in one hand is even more horrible. My argument for raising 2NT openers to game is "do I have what looks like an entry?" If the answer is yes, we're going to game; if partner can get to my hand once, that should be enough. As Phil says, the problem with that is that when it does go 2NT-AP, it's not making.

 

The other problem with 2NT as an opener is that it's a slam-killer - you're massively preempting yourself, especially if the end contract is 6m. But you have to have a call for this hand; and you have to be able to pull it out of your other calls.

 

2NT is a sucky opening, no matter what it is. It's a horrible contract if you're left in it, and it frequently leads to sub-optimal contracts. But the damage to the rest of the system of changing it is higher than that (or it would have been changed).

Can't be that bad, apparently playing 2NT-3NT as artificial isn't worth it. ;)

[gwnn]

2NT actually has the unlikely upside that it preempts opponents out of nice lead-directing actions like

 

1♣*-p-1♦**-1♠***

 

*-some alternative opening that includes 20-21 bal

**-negative or waiting or what not

***-LOLOLOL

Yet another spectacular failure of a 2NT opening bid promising 20-21 HCP. This hand was played in the Main Bridge Club earlier today.

[hv=pc=n&s=saj5hak98dkq3ck63&w=sk8432hqtd62caq97&n=s976h6432dj54c542&e=sqthj75dat987cjt8&d=n&v=n&b=5&a=pp2n(20-21%20HCP)ppp]399|300[/hv]

Partner and I have moved these hand types into our 1♣ bid (forcing for 1 round) after suffering similar losses of our own as here. 1♦ response is negative (0-4 HCP). Anything else promises 5+ HCP. The downside is that many 3NT contracts get played from the wrong side of the table. The upside is that we get to play in 1NT, either making or going down less than the rest of the field. We don't mind the downside as it's not hurting us yet.

OK if you play a forcing club, think I prefer playing something more traditional to play 2N than 1♣. I suppose in Acol at least I play 1♥.

North has about 13% of his "fair share" of the 20 points remaining in the three hands other than south. On top of that, the nineteen points held by the defense are extremely poorly placed for declarer. This is not a normal occurrence, it seems to me. IOW, you were unlucky.

Besides that, he hasn't told us the actual result.

[mycroft]

Plus, given that it's a lot easier for E/W to find their heart partial opposite 20 vs 3 or 4 if you open 1♣,...

 

(Not the example hand, but one from the instant matchpoint game last year that I was reading this morning, in fact. 2NT-AP, down 2 NV after 5 hearts, an Ace and time to set up the ♦K; but E/W are *at least* +110 in hearts).

Declarer made 3 tricks. This is what happened -

Trick

1 - West led the ♠2 to East's queen, ducked by declarer.

2 - East continued with the ♠10, again ducked by declarer.

3 - ♣J, covered by the king, won with the ace.

4 - West read the spade situation correctly and played the ♠4, won by declarer with the ace.

5 - ♥A won be declarer

6 - ♥K won be declarer

7 - ♥9 won by East with the jack

8 - ♣10 won by East

9 - ♣8 overtaken with the 9 by West

10-13 4th ♣, 2X♠ won by West, ♦A won by East

 

Hows that for a spectacular failure of the 2NT opening bid?

Didn't you misplay trick 1? Win with the ace.

 

Shouldn't you win 6 tricks?

2 spades, 2 hearts, and two diamonds.

Down 2.

Yeah, but it's 300 after the auto-double. :) (This was in fact the one and only time I've tried this.)

Fortunately we do not have too many Joe Grue arround.

I was sitting East here. The best declarer could do was 5 tricks the way I see it. Nonetheless, a poor result for N/S.

2 - East continued with the ♠10, again ducked by declarer.

3 - ♣J, covered by the king, won with the ace.

For this to be the play, Declarer would have had to duck the opening lead with the jack.

Blaming your bidding system for a bad score after playing the hand misere is more than silly. This goes back to the point often made on BBF that weaker players often think a bad score is down to their bidding because this is more visible to them, whereas the real culprit is often in the cardplay. Similarly, how many times does not having a natural 1♦ response to the 1♣ opening cost for every time where a 2NT opening goes down? How about that 20-21 point hand in competition - would you feel comfortable passing it out if the bidding came back to you in 2 of something? There are pros and cons of both approaches, even within a strong (or mixed) club framework; Meckwell use a natural 2NT opening for example. Within a natural system your case looks pretty thin, and no amount of cherry-picking is going to convince readers to the contrary.

2NT probably fails so often because declarer has to play mostly out his hand and has few opportunities to take finesses.

 

An interesting convention in MP's would be to "Trouble" DBL in 4th hand on most hands regardless of point count since you will get a top 60% and a zero in 40% of the times so on average a 60% score!!

If you include the requirement of having an honour in each suit or at least 2 filled 4-card suits (like J109x or Q109x) then the chances of declarer going down increase.

This because partner is less likely to blow a trick on the lead or suits won't run for declarer.

 

You will have to alert this since it is an unusual agreement. Partner of the opener could trap-pass if you double on any hand, but this is to risky if you include some requirements.

At IMPS it will cost to much if they make it. Maybe then it is profitable if you play that is promises 2 badly breaking suits.

Come on, Robin, there are some!

 

Indeed there are. The system alone does not define a player's ability.

[helene_t]

85% of 7NT contracts are made

It seems to me that an easy solution is available.

The following really happened at a hospital staff bridge club in Amsterdam:

 

1NT-p-3NT-a.p.

 

Dummy tabled a 0 count.

 

Declarer: why did you bid with that hand?

 

Dummy: My teacher taught me that 1NT is the most difficult contract to make and that 3NT is much easier.
