Perhaps they were playing a canape system … many of the early Itaklain systems such as “Roman” would open a 3 card suit befire bidding a longer 5 card suit

Chip, do you have any thoughts on big club systems? Have you ever experimented with such systems, wondering why many world-class pairs use them?

What is your favourite defence against a strong club?

All Bridge players suffer from personal delusion - - thinking they are a much better player than their results would show …. burst the bubble with a rating scheme may cost a few memberships .. any way back to the joy of Bridge

In terms of money efficiency I like OKBridge because :

1. ten 12 board tourneys per day (played in an hour or less)
2. can win 1.5 master points per tourney
3. only costs $150 per year (50c per day)
4. open tables to play on all the time
5. can quickly locate compatible partners and opps because of their Lehman rating system
6. increasing your Lehman rating is more fun than earning masterpoints
7. The Bridge is high quality for your rating

I like the idea that after 2/1 that rebidding same opening suit (or a lower suit) shows a hand in the minimum range (say 11-14 hcp) as a “waiting bid” …. anything above the trump suit shows extras and there awakens partner to slam possibilities. No need to differentiate between a 5 and a 6+ card suit when rebidding the opening suit.

By making a waiting or cheap bid, responder can now easily describe his hand in order to find the right strain. If responder is also slammish opposite a minimum, he can still make a slam try after locating the ideal strain.

What definition immediately rebidding 2nt (to show extras)can mean has lots of possibilities. That gets worked out around the rest of the system/

More importantly, with much shape to show, showing an initial “minimum” does not deny a “maximum” or extras; it is just comely planning a surprise later for partner (when you don't quit when pard signs off) that you have both great shape and enough extras to try for slam

Do you think you would love or hate playing a big club system?

Would it mater if the 1 overcall was alerted as a “scramble”?

Continuing with shape %:

8311 00.2
8320 00.1 %
8410 00.1
9x <0.1


COMPARE

4432 to 4441 = 21.6 v 3.0

5332 to 433 = 15.6 v 10.5

Two Suited 54's 5431 5422 = 13.0 + 10.7 = 23.7%

5332 or 55 or 54 15.6 + 4.1 + 24.9 = 44.5%

7 Card Suit = 1.8 + 0.5 + 0.4 + 0.2 = 2.9 %

65's = 1.3 %

Single six card suit = 5.7 + 4.7 +3.5 + 1.3 = 15.2 %

8 card suit = 0.2 %

Chances of having a 5 card or longer suit = 44.5 + 16.5 + 2.9 + 0.3 = 64.2 %

Putting some of this together makes it more interesting:

High Card Points & %

0-2 = 2.3 %
3-5 = 11.5
6-8 = 23.1
9-11 = 27.7 %

Non Openers = 64.6 % pf the time

12-14 = 20.5 %
15-17 = 10.0
18-20 = 3.2
21-23 = 00.6 %

Openers = 34.3 % of the time

(The rounding error is about 1% in total)

Some of my common HCP ranges are:

Intermediate two bid (9-12 hcp) = 35.7 %

Weak 1NT or intermediate two (11-14) = 29.5 %

Healthy suit opening (13-16) 20.2 %

Heavy NT Opener (16-19) 8.2 %

Big Precision Opener (17+ hcp) 6.1 %

600k boards from Vugraph: lies, damned lies, and statistics

The one concern I had was the most basic allowable meaning of a cue bid of opener's suit…. it used to be that it could be defined as a big hand, say of 15+ hcp and takeout-ish … when I last looked I think the language has it backwards disallowing the big hand definition on the lower level charts …. if so, then it needs to be rectified so its classical meaning can be utilized at all levels of skill

there is no reason all participants entered into bridgemate cpo;d not be sent a detailed email of the event before they even get home or to the bar …. with dealing machines and coordinated acbl wide events even greater juicy tidbits can be sent with great appreciation

Interesting that an artificial cue bid overcall (unless weak) must contain at least one known suit …. that would preclude using it in the classic sense to show a strong hand … for example we use it to show 0-1 or 0-2 cards in the cued suit and at least 15+ hcp and unlimited in strength …. what is behind such a restriction?

BTW we might also use it for any very strong one or two suited hands of game or neart game strength.

AND we also use the cuebid when we have 19-22 hcp and 3+ cards in the cued suit

SO we have 3 distinct possibilities for our artificial cie bid all 15+ hcp

1. short in that suit as a strong takeout or
2. a near game going hand probably one or two suited, or
3. strong in their suit and very big notrump shape

all of which appear to be illegal

the trouble with relays is that they must be bid perfectly … the slightest mistake leads to wild misinformation …. they need a dedicated partnership with both partners possessing a meticulous carefulness and perfect memory …. very few fit that unless a pro

AGREED IT WAS HANDLED VERY UNPROFESSIONALLY …. this would take tlc and wisdom but could be a huge win

We standardize our 2nt bid (in all types of competition) here as a constructive plus 4+ card support for opener's major (over a minor 2nt is a weak preemptive support hand

Too much of these comments are about what it was and not enough on what OkB is right now and how very much it has to give

I am there all the time ….. haven't seen it in a long time and i used to do your columns regularly … It says:

“Due to technical difficulties the Frank Stewart daily column is not being shown. We anticipate this being resolved soon.”

OkB has anew owner/mamager who has had much of the software rewritten and it fixed a lot of problems … he is trying to improve certain parts of the experience like expanding some of the tourney's for non-ACBL play but it is obvious he is not a Bridge player and because of it certain things still fall short

The most persistent problem is the lack of real Director rulings ….. answers are appeasing rather than fair … But beyond that OkB is an excellent site fot ACBL Tournaments - far better than BBO - and much cheaper

OkB's Lehman rating system is the best part of the site …. it helps you pick up compatible partners on a moments notice and leads to developing some long term partnerships as well … Two of my most rewarding partnerships were developed though OkB

I hope you get your syndication back up … It was an excellent feature

It looks like OkB is still a little tight for money but can see them turning the corner soon … if they do it will become one of the world's best Bridge playing sites again … in some ways they are already there
