An everyday hand♠


Recommended Posts

I will first give you one hand (my hand) so you can think about it if you wish. Then I'll give you the two hands and ask if you think this is error (whose?) or bad luck. The circumstances: I have just come in to an acbl tourney game as a sub, this is the first hand I have played, partner's profile says expert.

 

[hv=d=s&v=n&s=stht82daqt97c9874]133|100|Scoring: IMP[/hv]

 

I'm dealer, red against white. The beginning of the auction:

Pass (1H) 2C (2S)

3C

 

My thinking was fairly simple minded: If partner has a vul 2C bid, I have a raise to 3C.

 

The auction continued

 

Pass (1H) 2C (2S)

3C (4S) 5C pass

pass X all pass

 

 

Here are the two hands:[hv=d=s&v=n&n=sk6h9754d4cakqj32&s=stht82daqt97c9874]133|200|Scoring: IMP[/hv]

 

 

Off 500, it could have been 800 (W needs to cash his spade ace before playing the fourth round of hearts, E then ruffing with the ten). So 3C could have been beaten a trick.

 

Further, 4S can be beaten although it wasn't always.

 

What are your thoughts on the bidding?

With short majors, and this nice playing strength, I think 3 is an underbid. I prefer 4 even at r/w. I would never characterize 3 as 'bad' however.

 

5 looks obvious, but a deeper examination is that its a poor call. He has a dead K and the heart length is a real problem. And we are red on white.

Thanks. I thought of my own three card heart holding as something of a downer but still I have clubs, values and a stiff so 3C seemed right.

 

Perhaps of note: We have ten clubs, they have ten spades. We can take eight tricks in clubs, they can take nine in spades, that's the limit and requires no great defensive ability to hold it to that. One of the defensive tricks in a club contract arrives because of the lucky location of the ten of clubs but otherwise there seems to be nothing special. So LOTT is more than a bit off. Nothing works all the time of course.

Hi,

 

#1 3C looks normal, if one has agreed to play fit non jumps,

3D is fine, but random pickup, means you should play it

safe, so 3C it is.

#2 2C looks normal

#3 given the vulnerability 5C is sick, since you dont bid 5C

with the expection to make, hence you bid 5C as a sacrifice,

but a sacrifice red vs. green is certainly not the most brilliant

idea.

 

From #3 followes, it was an error, and the error was bidding 5C.

 

With kind regards

The LOTT becomes unstable with mega fits.

 

Unstable means, that on average, it still holds, but the variance is fairly high.

In the given situation, you have 20 total tricks, mega fits start with 21-22

total tricks, this statement is similar to gwnn's comment, but more important,

using the LOTT for 5 level decision is dangerous.

 

Anyway using an LOTT based analysis:

Assuming we have 17-18 total tricks, if we make 5C (not a realistic

assumption), they make only 6-7 tricks => If we double 4S, we will

on average earn more money, hence defending 4S is better, you may

or may not double.

 

If they make 4S (a sensible assumption), we only make 7-8 tricks in clubs

=> hence a double of 5C is clearly in the money for them, hence defendng

4S is much more cheaper for us.

 

So in the end the LOTT tells you not to bid 5C.

 

With kind regards

Well, the analisys was also flawed. For one thing, we aren't doubling 4S. For another, we don't know that there are 17-18 total tricks, and there is no way to know.

First of all, the intention was only to show, that the

LOTT does not recommend bidding 5C, so hiding

behind the LOTT is no use.

 

Regarding the flawed analysis:

 

I did not suggest to double 4S, only if you assume 5C

makes, the LOTT tells you, that you may consider to

double 4S.

And assuming that 5C is making, is taking a very rosy

view, to put it mildly

 

Regarding the 17-18 total tricks:

The 5C bidder knowes, that the partnership has 9 trumps,

they will bid 4S only with an 8 card fit, which will quite

often be a 9 card fit, that makes it 17-18.

 

The king of spades is a neg. factor, which reduces the

number of total tricks, so even with greater fits, the number

of total tricks will be lower than the number you get adding

the best fits of both sides, so taking 17-18 as a basis should

for your argumentation should not be too far away off from

the truth.

But look at how much shorter it is to just think about bridge!

I agree for sure.

 

I just wanted to point out, that the LOTT does not

suggest bidding 5C, to counter any attempt to discredit

the LOTT.

 

The LOTT works fine, as long as you dont stop thinking.

 

With kind regards

I was not sure I should even mention LOTT. I did not mean to suggest that LOTT would lead anyone to bid 5C. I simply was mulling over the fact that with twenty total trump there are seventeen total tricks and thought I would mention it for what it is worth.

 

The general comment that thinking is better than blindly following laws is of course correct. The suggestion that LOTT becomes unstable with megafits and the suggestion that it may not be a great tool above the three level are observations a person might factor in when considering how and whether to apply LOTT.

 

The LOTT has been the subject of much discussion on the Forum and I was not really trying to start a rerun.

 

The hand is of an elementary sort involving no particular conventions (unless 3D instead of 3C would have been a fit showing jump but even with regular partners I do not play that to be the case). It worked out badly so I was wondering about what folks thought, and it seemed suitable for B/I.
