At my local club there is a master player, a professional, who often
plays with inferior players. They seldom win and at times come in
below average.
Why are pairs not rated by their average masterpoints or possibly by
some weighted average value, such as 2/3 of the higher +1/3 of the
lower player's point standing? I doubt that a silver LM +a novice can
do any better than two bronze players together.

I'll bet that for any two bronze life masters, I can find a silver
life master/novice partnerhsip that is better. That is, if you are
using masterpoints to determine what a novice is.
Tim
Maybe if the novice is someone like Frances H but in general if the two Bronze
Masters are on their way up that might well not be true. I am sure there was
a time when some of the Polish world class pairs were both Bronze life masters.

Pairs aren't "rated", as far as I know. So I assume you're referring to
how they're assigned to flights or strats in tournaments.
Flighting is mostly a reaction to less experienced players being
intimidated by having to play against experts, as well as experienced
players having to "put up with" novices (it's hard to read the cards if
the opponents don't bid or play reasonably). These concerns are valid
even if just one of the opponents in a pair is at the specified level.

Actually, most of them aren't life masters at all. They lack the silver or
club points.

ACBL life masters, a lot of other NCBO's have a Life Master or equivalent
title and these players usually have LM status in their home country.

That problem that we weren't having yesterday, is it better? (Big ISP NOC)
Probably it's simply the fact that there is no "right" formula, combined
with the following rules:
(1) Competing down is considered unsporting.
(2) Competing up is considered sporting and adventurous.
Taking the highest value, then, avoids the appearance of (1) in all cases.
=thomas
And anyway, at least in the ACBL, there are tournament events that
don't work as Stig says. In bracketed KOs, the bracketing is based
on the average<*> number of masterpoints of all the players on your
team. Okay, that's not pairs, but I've also played in pair games
that were stratified according to how many players on the pair
were above a certain cutoff number of points. This format was
known by the rather meaningless name of "stratified by experience".
I haven't seen it for a few years, though.
<*> In practice they actually use 4 times the average, which gives
the same result and is easier to compute since most teams in these
games have 4 players.

He has plenty of them. He would be playing to help a non-LM player
gain points. It is a pair contest not an individual one.

Stig,
That line (A silver LM ...) occurs nowhere in my post.
=thomas
Hello from Moscow, Stig!
From purely MATH point of view the following rather simple formula
might be of use:
Score_of_Pair = 2/ (1/Score_of_Player1 + 1/Score_of_Player1),
Where by "Score" one can use Masterpoints or any other measure with
property "the more -- the better". Please note that factor "2" appears
due to final "Score" applies to TWO players. For 3 or more players one
should extend formula in brackets and change factor from 2 to 3 (or
higher).
What's the effect?
Consider a Player 1 (Novice) having, say, 10 MP. Players 2 has 100
MP.
Formula yields:
10 + 100 --> 18.2
Now let's change MP levels for some extent for both Players:
10 + 200 --> 19.0
10 + 500 --> 19.6
12 + 100 --> 21.4
15 + 100 --> 26.1
So, "playing strength" of a pair would not change much when "Expert"
is replaced by "Champion" (200 MP or 500 MP instead of 100 MP).
At the same time even slight change in "Novice" scoring leads to much
higher levels of Pair Score.

I'm trying to decide whether to complimented or insulted....
It's true that I have a grand total of 1.2 (I think) ACBL
masterpoints, however in common with most of the world's bridge
players I play 99.999% of my bridge outside the ACBL. I am usually
not considered a novice at home.
1. I play as follows:
a) What I mean by ASPTRO is:
x=penalties
2C = hearts & another
2D = spades & another
anchor to longer/better major
2M = natural
The strength required depends slightly on your suits: 45 in the reds
can bid more freely than 4M with 5 clubs as you can pass the 2D relay.
b) In response to an ASPTRO overcall I play as follows:
(1N) - 2C -
2D = to play opposite a 5-card suit (opener bids 2H with 5H4C, 2S with
5S4H, 2NT with 4H5C), usually denies 3 hearts
2H = to play (either 2-2 in the reds or 3+ cards in hearts)
2S = to play
2NT = natural, invitational
3C = FG relay. Overcaller bids as follows:
3D: 5H + 4-card minor (3H asks, 3S=clubs, 3NT = diamonds)
3H: majors
3S: 4H5C
3NT: 4H5D
4C/D/H: 10+ cards in the two relevant suits
3D = high-card invitational values with 3-card heart support
3H = invitational, 4-card support
3S = nat FG
3NT = nat NF (often has a long minor)
4m = not sure we've discussed these
Similarly after (1N) - 2D, though responder can't sign off in 2H the
way she can sign off in 2S after a 2C ASPTRO overcall.
The order of the bids after the 3C enquiry is to allow all 54s to show
their distribution below 3NT.
Note we are usually defending against a weak or mini NT where game on
HCP is a serious possibility, hence (at least partly) the natural 2N
bid.
2a). 2NT = game forcing 2-suiter. Strong 1-suiter doubles first then
bids its suit. (A strong 1-suiter than doesn't think it can defeat
1NTx will bid immediately at some appropriate level).
b) 3C/D/H/S pre-emptive
> 1. I play as follows:

Isn't asptro when you anchor to the shorter major?

I play 2H here as 4+ hearts or 3 hearts and an outside singleton. With
2-2 in the reds I would prefer a 5-2 diamond fit to a 4-2 heart fit,
if partner has 5 hearts he will correct 2D to 2H.

I like this a lot, I'd never considered using 3C in this way.

I use 2NT as the minors (5-5), mainly because I can't remember ever
having had a GF 2 suiter in this position, and when I do I will
probably be greedy and try to extract a penalty first!
> b) 3C/D/H/S pre-emptive
I play these as pre-emptive as well.

Good point. As the number of members of a team increases, the likely
influence of any one member decreases. In a pair, one player can
"mastermind" and try to become declarer more than his fair share of the
time. But in a team of 4, the "expert" can't do anything to influence
what happens at the other table.
Wow, if you mean the same Frances H as the rest of rgb contributors, then you are
way off the mark. And on a day when she won Swiss Pairs in Brighton ahead of
Tony Forrester, Andrew Robson, and many other fine players (the biggest congress
in Britain, for the non-EBU readers). Congratulations! Some novice, really...
Tell this to Cambridge folks, even now that she's been in London for good ten years
I think.

see above comment about gooey mess between ears.
but 2H doesn't have to have an outside singleton; with a 4324 I might
bid 2H at mps if I have enough cards to think they are both making.
Oh yes, according to my system file, so do I. Good job it didn't come
up...
This is not doen the same way throughout the ACBL, is it? I'm pretty
sure I've seen KOs bracketed by masterpoints held by the top two
players or by the top 4 players, rather than by average.

However, with a team of six, the best player may be as much as 1/4 of
the team, and the worst player as little as 1/8. On a team with a
sponsor, the sponsor is likely to play only half the matches.

Some pros have an extraordinary ability to drag you over the line.
Within 3 years of starting to play bridge (from scratch, you know
where you get told the suit ranks in the first lesson) I had
1) come 12th in the world mixed pairs (that was in my first year of
play)
2) come 3rd in the Australian Butler pairs (used to be their
international trials)
3) qualified with about 60% for the European Open Pairs final in
Sorrento
all playing with my ex-husband Michael Courtney. At the time I thought
I was quite a reasonable player (at least I managed to keep that to
myself). Relative to that company I was (and still am) utterly
hopeless. My favorite self delusion is that I thought I was a good
defender :-) Well I was until I had to defend with anyone else.
I wasn't a typical novice but after 6 years David Burn told me when he
was coaching me that I was a bad "good" bridge player which I think is
a fair description.
Micahel is an incredible player but he further has this talent for
dragging novices screaming and kicking over the line (I have seen him
do this with loads of people). And he isn't *that* hoggy in the
bidding.
Our chain was hugely stronger than our weakest link.

My experience with these games is limited to NABCs and the regional
here in Toronto. In recent years they have always asked for the total
points of all players, so effectively working with the average (see
footnote in previous posting), but I won't say that Tim's wrong.

OK. So, presumably, according to David Burn we have good & bad "good"
players and good & bad "bad" players.
Am I right in further assuming that the above categories translate,
respectivly, into strong & weak scientific players and strong and weak
intuitive players?

++++And "complete bloody idiots". Which one isn't supposed to take
personally.
Have you ever obtained the impression that 'scientific' players think
that the game belongs to them? To a point where non-scientific
players have no business at the same table as them? Or as members of
the same club?
> Have you ever obtained the impression that 'scientific' players think
> that the game belongs to them?
++++No. Not really, I mean. And I don't really understand what you mean
by scientific. Where does one draw the line? I don't know about you, but
I'd have thought that knowing common suit combinations was pretty
vital for any sort of mild success at the table. Is that too scientific
for a true 'flair' player?
> To a point where non-scientific
> players have no business at the same table as them? Or as members of

++++I think this is a non-argument. You could level accusations of
unfriendliness and aloofness against nasal types with biros sticking out
of their shirt pockets as they rant about percentages and so forth, but
you could make an equal case against 'flair' or 'intuition' players as
they resolutely patronsied the scientists the four times out of ten that
the sixty percent line didn't work. "Could have dropped me Queen!" They
crow.
At this point I would like to point out that I have no axe to grind,
having a mind too packed with useless aracana to absorb mathematic
detail, and being totally bereft of any flair, style or intuition
whatsoever. "Why not give up?" I hear you cry.

this is why people don't play dont against a 12-14 NT.
What an auction on the first table anyway...
Just out of curiosity: Did North try to grab his two Aces, or did he
hold off on the clubs to protect his trump King? Did East make anyway
(two clubs, then three rounds of hearts pitching the club, perhaps?)

Even playing penalty doubles, +100 is a terrible result. That's why
2NT must include powerful freak hands, not just minor two-suiters. At
mathpoints, you could shrug this off. At teams, any method that risks
stopping short of game (or forces you to guess which game) with the
East cards is absurd.
Maybe I'm missing something, but why wouldn't a diamond or heart lead beat it?

I was reminded of this thread in the course of playing the other
night.
North at one table was one of those players - they always seem to be
women - who think it incumbent on them to grab and unfold the
traveller to use the various results on it as kind of agenda items for
her to chair a discussion on how the hand should have been bid and
played.
Writing down the score was the lowest priority, and the consequential
build-up of delays had goaded N&S at the next table to a high degree
of vigilance, as in: "Director, you have called the move, and they are
starting a board!"
In the course of one such wretched post-mortem she said to my partner,
"If *I* had had just a few more points, I would certainly have doubled
you for penalties." In a tone that came very close to 'gotcha'. So I
thought of this thread, also of all the poker post-mortems that boil
down to nothing more than "If *I* had had a better hand than the
winner, *I* would have won *that* pot!" - and I resolved to think more
kindly of those bridge players who slap the next board down on top of
the previous board's traveller, and manage to plonk down card(s) from
the bidding box before said traveller has been extricated and returned
to its board.
Especially the ones who then seem mutely to accuse North of hesitation
as soon as she has sorted her cards for the new board. They are not
as rude as I used to think they were when I first encountered them!
