Re: the Butler scores from the round robin…

http://db.worldbridge.org/Repository/tourn/wuhan.19/microSite/ButlerBB.htm

…I recall reading skepticism about the value or accuracy of Butler scores as a measure of the “best” pairs. But the only specific concerns I can remember are sample size and variable quality of competition faced.

What does this expert group think…is there any signal in this noise? Is the sample of 200+ hands adequate? Is the quality of competition faced by different pairs over those boards likely to vary enough to meaningfully skew the results?

Recommendation for BridgeWinners management: the World Championships should have their own “Featured Article” thread just like all NABCs.

I love my bridge, but I honestly wish that those involved in governance would find better things to do with their time than focus on this, or other, feel-good but substance-free gestures.

The uncharitable view of someone who doesn't want to hear advice from qualified opponents is that they are close-minded or hubristic.

A charitable view is that they are following Bob Hamman's advice to mentally move onto the next hand, and want to leave ANY post-mortem until later. Another is that they already recognize their mistake.

Until you land in situations in life where you are specifically engaged or identified as a mentor/coach/advisor/manager, recommend that you simply never offer unsolicited advice in competitive or professional situations; it will rarely be well-received. Don't try to understand it (your attitude is far healthier), just accept that is how most people are and don't risk offending.

@ Richard R…2 is most definitely forcing. For one round.

@ Richard F… by immediately raising 2 to 3 arent you risking losing a 44 heart fit?

The real competition in these events are the other humans sitting in your seat with your cards playing the bots at their table.

From that perspective, the 55% tournaments mentioned in the OP are not “clubbing baby seals”; there are decent players in this flavor of tournament, or at least much better players than in other types of BBO robot tournaments.

Other – I sometimes have no strong feelings, but want to see how experts I respect have voted. I can't see the names of who responded how unless I vote or abstain.

I also want to know how light we will overcall. Would something like xxx AQxxx xx xxx bid 1H here?

“As they apply it, they will learn when the rule works and when it does not…”

Pretty sure this is empirically wrong for the vast majority.

I agree with using rules as starting points, but the problem is that too many teachers (maybe including Colchamiro?) stop at the rule and don't even try to give students the more complicated tools or thought process to eventually transcend the rule.

I'd support Michael's idea if and only if each team can pre-specify the ensuing KO event(s) for which they want to be eligible. Lower-point teams should have the right to say they are NOT candidates for the open KO field. I do not want to see a lower-point team – who may be targeting a deep run in the “Mini” – tank late in the Swiss if they're on track to qualify “too high.”

What's the back story on why Robb Gordon asked to be briefed on this system?

We don't make crappy two-suited bids on nothing that paint a picture for the opponents' play of the hand when we have little hope to win the auction except in misfits.

I was the bidder Richard cites from the other thread. While I'm not entirely convinced I was right there, the bid was made in 4th seat over a 3rd-seat opener on a deal that was almost certainly a part-score battle. So I think it's a different situation than we see in this thread.

Yesterday I made two 3334 takeout doubles in the two-session open pairs event in Vegas.

First with Q93 Q53 AK85 QJ4 in 4th seat (us vul) after RHO opened 1.

Then with AK75 932 AQ2 Q86 in 3rd seat (nobody vul) after RHO opened 1.

Our card is not marked for offshape TOX.

Do folks quibble with my bidding choices or CC presentation?

Yes, apologies…the Round of 64 concept is somewhat nonsensical. So instead focus on the absolute number of ~150 experts…that's a better definition of the line that seems drawn quite high to me.

Why is Round of 32 any more sensible than Round of 64 or even a somewhat higher number? This seems an incredibly high line to me.

Not true.

The recent King of Prussia regional had 2-day BRACKETED KOs that started with a Swiss on Day 1 and KO on Day 2…but it did NOT have a two-day event with an OPEN Swiss that fed into Day 2 KOs.

However big the segment of A players willing to play down is, I don't expect more than a handful (if any) will be BridgeWinner readers
