scores...

[hanp]

BTW, I have finished the scoring all 16 boards now but I am not saying where anyone else ends up until all pairs are finished.

 

Pleeeeease???

Well, since you ask nicely, i posted the current rank order standing. We have a new leader and a new 2nd place pair. But all that counts is to make it into the top 1/3 (10 positions) to move into the upper bracket.

mmm maybe if I create 100 fake accoutns for 50 fake pairs and participate, I can promote Codo and me to the upper bracket.

 

Oh wait, I would had to find 50 ways to do it worse than codo and me, that's impossible lol.

[Codo]

Don't worry, if you find 20 ways to make it worse, I will freely contribute the other 30. :)

Note that GIB and jdonn are making their move. The good news is that GIB won't complain about the scores.

Question about the scoring:

 

After bidding a hand, you can see the entire layout (not just the hands you bid). There are some cases where this layout includes some unusual suit breaks or card positions in the opponents hands, which would result in one or more contracts which seem okay single-dummy faring poorly in practice.

 

To give an example while avoiding saying anything about the actual hands, suppose that there was a hand where we have only 22 hcp but 3NT makes any time one of two finesses is on. Single-dummy, it seems that 3NT is a good bid, quite possibly the top spot (assuming no other game has significant chances anyway). But suppose that the opponents hands reveal that both the two finesses are failing, so given all four hands avoiding 3NT leads to a better result.

 

How will these be scored? Is it on the basis of all four hands? Or on the basis of what "would be best single dummy" given the information from the bidders' hands and the auction?

Question about the scoring:

The relevant portion:

 

The actual NS hands you see when you bid are not imporrtant.

 

Don't do that. Look at your hands and ask yourself, is this the contract I want to be playing.  The NS bidding will affect this decision of course. If your RHO opened, and they have only 11 hcp, you can assume all the hcp are with RHO and if that makes increases chances your contract will make great, by all means that will be taken into account.

when does the first round finish?

[Hanoi5]

'twas supposed tobe today but Inquiry is in NO and 4 o5 pairs haven't gone through.

[gnasher]

We achieved a remarkable 75%. That is, on 75% of the deals we didn't mess the system up.

 

Thank you to Ben for organising it, and to Sally for hosting our table.

[hrothgar]

Any place we can see the scoring tables?

Thinking about the scores made me appreciate how much effort is put into the selection of hands for The Bridge World's Challenge-the-Champs. At CTC, the scoring is strictly matchpoint expectancy in a very good field. That means that you can't even use a hand where the top spot is a 75% 4♠ contract, where you expect some of the field to be there and the rest (majority) in part-scores: 4♠ will tie against anyone else in the same contract, and beat any partscore 75% of the time - which means it's matchpoint expectancy is s.th. like 65%, or 8 on a 12 top. And of course you want to be able to hand out one better score than that on any hand.

 

On the other hand, I enjoyed bidding the BBF contest's hand much more than bidding CTC hands, as it wasn't as frustrating :) It was easier to get to the top spot, and even when we didn't get there, it wasn't quite as obvious as that another spot was better :)

 

(And this isn't criticism of Ben's selection in any way - I am sure I would have done a worse job than him selecting the hands. There is a reason I haven't gotten an offer to replace Eric Kokish in selecting the CTC hands yet :).)

[TimG]

I agree: it provides a new appreciation of the BW selections.

 

I also agree that it is fine if a few more routine hands slip into BBO forum contests, it's not really a bad thing if almost everyone passes the test on a few deals. If nothing else, it may reduce the tendency of participants to look for the trick in every deal. When bidding CTC hands, you can be pretty sure that when your auction is 1N-3N you've missed the top spot, for instance, so there may be a tendency to look for the unusual.

 

I'm curious how the results would be affected if the contracts were ranked and then the participants matchpointed based upon contract reached.

I also liked the way that it felt like a set of normal hands.

[Cascade]

I thought they were good hands.

 

I really enjoyed bidding them even if we didn't always get them right.

[Mbodell]

I also super enjoyed it. One thing that I think would be good to see at some point (if convenient or easy to display) is the auctions as well as the final contracts. That way we could all see and argue about which bids were close/wrong and learn different people's systems.

 

That may also help deflect some of the discussion of the scoring on individual boards towards the auctions in question.

[bluecalm]

Our score is 111/160 anybody else care to confirm theirs ? Especially people around 10th place :)
