Round 1, Board 4


Recommended Posts

[hv=d=w&v=a&w=s632hkt7543d872c4&e=skqj7haqdk543ck65]266|100|Scoring: MP

Board 4. Bidding Script: North will open or overcall in 's as cheaply as possible, but not above 3. He will keep bidding 's until 3 is reached. If north bids 2 it will be south who carries on to 3 if necessary. If west or east end up in 4's or higher (in any denomination) south will double.

 

Notes: When played in real world, most seemed to think east is a little heavy for 1NT, no doubt due to the increased lighter and lighter nature of the 1NT overcall. The auction should be fairly straight foward with a 1NT overcall. West will try transfer to 2, and East will probably pass over 3 by north, so that west will be in position to take the push to 3.

I'm not sure why 4X scores any points at all here, as it seems like a sure bottom board (-200 if you're lucky).

 

I'd also note that 3X is a top any time the contract fails, which I'd rate as rather more than the 20% odds which the current scoring seems to rate it at.

Well, your two comments point out an inconsistency if 3X makes anything close to half the time, then 4X is unlikely to be a bottom (I don't think -3 is that likely).

 

Also, if 9 pairs in the contest ended up in 4X, it seems the -200 (or -500) will not be that lonely or uncommon a score. Bad yes, worse than 10%, no way.

The hand in the movie for NS made heart contracts look bad.

 

I thought the 3 rebid was reasonably frisky with the hand shown. Bidding 3 with that hand is offering 200 or more reasonably often.

 

That makes the heart contracts look bad.

 

If north has all of the aces which I feel is more consistent with the bidding then 4 is a much better contract and is very unlikely to be doubled.

BTW: south didn't bid 3 at our table

 

1-X-ps-1

2-X-ps-3

ps-4

 

 

Not sure what the meaning of carries on to 3 is.

It says 3 if neccessary. I wondered why so many pairs bid 4 over their partner's sign-off in 3...

Hmm ,the diagram above says West is dealer, so we will assume a pass before 1.

Why is 3H by E worth only 1 point and 3H by W 10?  It should rather be the other way around imo... Or is it a typo? Anyway we got 10  :)

That's a frequency chart, not a score chart.

Right zzzzzz

I don't get the scoring method.

3 is normal contract and there is no way it would score a top at MP's.

It seems that some hands are scored by one method and other by different one.

 

Any sane pair (not us) should have no trouble staying out of 4 so bidding 3 would net you 60% board - tying with all sane pairs, beating all the idiots (like us) :)

In this contest, 11 pairs stopped in 3 while 10 pairs reached 4. So, I don't think your premise that "any sane pair should have no trouble staying out of 4" is correct.

Not entirely sure what to make of suggested scoring changes here.

 

For awn's comment that 4 should get a zero, 4x scores better than both 4xx and 4x, both of which were played in this competition, in addition to 9 pairs playing in 4x tying each other. Maybe I didn't score it high enough!!! I was thinking along the lines that -200 is a zero-ish. Furthermore 4x will outscore 3x making, so I could see a counter arguement that it needs to be bumped up just a little.

 

I agree 3x is a top or bottom. I thought 3x was making somewhere between 30 and 37% of the time. If it was a percentage points lower than 30%, it would be a 3, if it was higher than 37% it would be a 5 or higher. I thought this was a fair placement for that contract.

 

As for why a 10 for a reasonably normal 3, I have two answers to that. I tried to make maximum on each hand at least a 10. See the hand where everyone bid 4. That is probably not the best thing to do, but I confused myself initially by picking out hands based on specific NS hands, but that isn't fair way to do this. Round 2 will avoid this flaw in hand selection. Still on the given results. Having said that, if we matchpoint the 26 boards here, giving a top to the 3, we find it earns 21.5 out of 26 possible matchpoints. As a percentage that is 82.7, and on a 12 point scale that works out to be 9.9. I don't calculate the matchpoints this way, however, I just used it to check teh arguement that heart part-score should be average on this hand.

 

So for the moment, the scores are staying were they are, but open questions are:

 

Should 4x get a higher score?

Should 3x get a higher score? Should it get a lower score? I will try some simulations.
