Verdict:  A light opening (perhaps counting a 10 and two 9s) should cause East
to unilaterally bid game - not the best game, but a good one on the actual
cards.  Otherwise, the specific agreements of the opponents come into play: 
West is correct to pass a typical 20-21 point 2NT opener with this hand, but
should raise the less common 20+-22 range. Easts who upgrade to a 2\C opening
will, of course, get to game - these auctions rate worse for North-South,
since East-West get to choose - and if playing puppet Stayman, to choose the
superior heart game.  GIB took one too many bids against a particularly poor
auction, turning a decent score into a bottom.

Verdict:  This hand was made for ES with my bidding trick.  The auctions are
riskier when the opening could be 11 HCP, since North will still drive to
game, so the LoTrip auction scores a point better.

On the Quad auction, short diamonds could produce a club slam, e.g. \SAxxx
\HAQxx \Dx \CJxxx.  This hand caused me to add the cue bid to the repertoire. 
North is right to assume club shortness, when south has diamond length.  Turn
three of those clubs into spades, and North has an easy double.

Verdict:  3NT is the normal contract, and all systems should get there. 
West's preemptive bidding should be contained to the 2-level by unfavorable
vulnerability.  Nevertheless, the Unbalanced Diamond auction seems inferior,
since North never knows of the club fit.  GIB's opponents allow both partners
to know about the club fit and then settle into 3NT.  While a slam can be made
on these cards, it takes two finesses, so 3NT is the top score in the bidding.

Quad:  2\C - 2\D [game opposite midi]; 2NT [long \H] - 3\C [pass or correct];
3\D - 3\SN  =6

Verdict:  Game requires a trump split plus one of two finesses - and some
handing - not a great prospect.  Opener should devalue the \CA.  In the ES
auction North might try for game, perhaps with the auction 3\C - 3\H [dang
stiff A only worth a retry] - 3\SN.  

The Mini auction contains a hidden weakness:  the extreme riskiness of
shooting for game with a 2NT response, which could result in a 4\C contract
opposite spade shortness.  The Split North had the safe option of a 2\H
response; game is possible but unlikely opposite 11-14.

The LoTrip North has interest in 4\S opposite a maximum mini, but subsides
opposite the minimum 3\S rebid.  The Quad auction, with ranges a point lower
than LoTrip, is driven to 3\S by the artificial response that was selected in
case opener might have a midi.

4\D.  The Triple and Quad openers should double for takeout to show this fine
hand; East-West may find it difficult to double or to set 4\D.

Against GIB, West's silly redouble allows North to bid his suit, but it comes

Verdict:  Another wheel came off for GIB, as the diamond slam takes decent
breaks plus two finesses.  3NT is the normal contract.  

The LoTrip auction is slightly inferior, with 2NT getting the dreaded 3\S
answer.  Responder had the choice of bidding a suit, pass or correct, but
perhaps that would have missed a game.

In the Unbalanced Diamond system, the limited 1\C opening (usually 15-19) and
1NT response (10-13), made it clear slam was unlikely.  The ES (or 2/1)
auction should get to 3NT, with some concern a slam is being missed.

Verdict:  On Leaping Truscott and Michaels auctions, West could get caught for
500+ on this partscore hand.  However, for the ES auction, South can't quite
double for takeout, and North can't quite double for penalties.  200 or more
should still roll in.

For UnbalD, a top playing Miles' recommended system, negative free bids and
possibly strong negative doubles.  A disaster for methods that Mark and I
tried, due to the lack of a 5-card suit in the big hand (2\S by South would
promise 5):  1\C - (2\H) - X [6-9, any shape] - (P); 3\CS.  This disaster
would be partially averted by playing HiTrip, LoTrip or Quad.

On the LoTrip and Quad auctions, North should judge that game is unlikely
opposite a midi, and sign off at the two level.  The 2\S response to the
LoTrip opening is fine: 3\H should be quite safe, if opener is short in
spades, although the contract would be the same if North had no high cards. 
The HiTrip auction is equivalent, since North could move with 18+.

A Blue South who stretches to open 2\D with the stiff K will likely go down at
the 3-level.

Verdict:  Some ES Souths might jump raise to 3\S on this hand; either rebid
could be right - not a strong auction, but effective either way.  On the
UnbalD auction, opener's jump raise shows 4-card support in a less than
maximum hand with a singleton somewhere; 4-4-4-1 is only one of the possible
distributions.  This 11-13 bid permits no invitations or further inquiries, a
disadvantage.  North carries on to 4\S, but with doubts.

North should devalue the \DQ, upon discovering shortness opposite.  The Mini
auction includes an invitational sequence, an advantage here.  On the Split
auction, the 3\S bid also shows game interest, having bypassed 2\S.  South is
pleased to accept on this fine 13-count.  LoTrip and Quad auctions move
smoothly to game.

Verdict:  On this hand, clubs are 4-4 and the spade hook is on, so both 3NT
and 5\D make.  Without a club lead, 3NT makes overtricks when the spade
finesse is risked, a good bet after an opening bid.  Against GIB and ES, the
opponents are well placed to guess one or the other games.  The UnbalD
opponents do not have a cue bid against the artificial 1\D opening.

After a three suited opening, West can count on 4-4 splits when needed, and
thus can bid 3NT with some confidence.  The presence of good suits enables
solid East-West bidding.  Some LoTrip Souths would open, given both majors and
two 10s, with an auction equivalent to the other three-suited openings. 
Passing leaves the opponents without the information that clubs are splitting.

for shortness, which gets you to 4\H.  Perhaps the double should say "cards",
as with other overcalls - or use the thrump double, asking opener to bid 3NT
with a stopper.

Verdict:  The LoTrip and Quad auctions keep West out, with 3\C the place where
North plans to hide if South is short in spades.  A survey at MIT/DL BC
selected a final 3\S bid, not 4\S, for North, knowing about the actual club
distribution.

The Mini and Split auctions would otherwise have ended at 2\S.  This is a thin
game somewhat improved by the \CK being onside.  However, swap South's club
and heart holdings, and game is a good proposition.  A North playing Mini who
bids 2NT would be committed to 3NT or a 4-3 fit at the 4-level, opposite spade
shortness.  A North playing Split could choose 2\H, as with LoTrip.

The one-level openings allow West to get in quickly.  North then risks an
off-shape negative double, which works out:  South bids spades, holding hearts
in reserve.  While the bids are the same for ES and UnbalD, the latter is much
riskier:  playing negative free bids, North's removal of 3\H to 3\S would be
forcing.  North's alternatives to the double would be Pass (probably playing
3\CE), 3\S (possibly declaring there in a 5-1 fit), or 3NT (an overbid).

Quad:  2\C - 2\D; 2NT - 3\D; 3NT [5 controls] - 5\S; 6\SN  =7

Verdict:  A black slam is laydown, ruffing diamonds, with splits in both black
suits: .68*.68, or about 47%, as one even split improves the chance of
another.  Still, looking at the North-South hands, you should usually prefer
to stay out of slam.

If ever there was a 13-point 4-4-4-1 hand for an ES jump raise, this would be
it.  North quits over the minimum 4\S bid, suspecting club problems.  On the
well-judged UnbalD auction, North also detects club problems, and signs off. 
Bidding on would not be that bad, especially if South has four club honors, or
\CAKxxx.

Playing Mini, North has no tools and therefore signs off in 4\S.  Playing
Split, LoTrip, or Quad, once North finds out he has all the controls, it will
be hard to stay out of slam, especially if South counts his 10s.  The LoTrip
auction is inferior:  they just barely have room to subside in 4\S if a
control is missing, and 5\S would not be invitational.  This board should be a
swing, depending on the splits.  Top score goes to investigating the slam, and
stopping short.

Verdict:  A poll at MIT/DL BC chose 4\D by North, knowing South has 15-17 and
a singleton heart, without competition.  Second choice was 3\H (control ask). 
After an invitational 4\D, South has a fine hand, but a minimum, and will
probably pass.  The \H10 is a big card.

When East decides to help out, the odds for 5\D improve, as East may have both
heart honors.  HiTrip has a happy accident of the range:  South has a max
within 14-16.

North is really hamstrung on the Mini auction - would you like to play 4\D
opposite an 11-count and a trump lead?  This auction does shut out East, and
it would get to 4\H opposite diamond shortness.

The GIB East's silly double hands North-South a top.  Don't like that 3\S bid,
though.

Verdict:  The Blue auction just barely provides sufficient space for North to
investigate game, yet stop short at an inferior 3\D.  [North could take a
position, and pass 2\S.]  The auction commits to 3NT opposite a 19-20 maxi-min
and a singleton spade, which seems acceptable.  Note that a 2\S response also
gets to 3 of a minor on this South hand, but misses many a game opposite a
fit. 

GIB is off the wall again, a 24-point game on a misfit.  The ES distorted
reverse auction works much better - what's one card short in a minor, anyhow? 
Playing UnbalD the limited 1\C opening and 2\Drebid on a 4-bagger is the best
that South can do.  It works out well this time, but South would bid 2\D with
a diamond one-suiter.

The LoTrip and Quad  2\S bid usually denies game interest opposite a midi,
which is what South has.  However, game would be laydown if South had \SAxxx
and a stiff club.  These auctions do land in the top spot from the correct
side.  The HiTrip North similarly guesses against a spade fit, but cannot get
to 2NT.

Quad: 2\C - 2\D; 2NT [long \H]; 4\HN  =5

Verdict:  4\H is an acceptable contract, but for the diamond split, and might
still make - possibly doubled.  4\C is a great contract for East-West.

The light, natural ES opening at the one-level, holding both majors, might
turn out poorly, letting the opponents find their club fit if East has a
sandwich 1NT in his bag - or if West tries a nasty 2\C overcall, largely to
steal space.  South might refuse the game try, with soft spades.

The UnbalD auction avoids the sandwich bid: only one suit has been bid
naturally, when the auction gets to East; a 2\C overcall by West would also
have less going for it. The singleton could be in any suit, and the auction
would be the same - not so nice, if it's diamonds.  The Quad auction is
equivalent, as North's 3\D inquiry would drive to game and thus would not help.

The Mini North cannot afford to try 2NT, lest a 3\H response result in a 4\D
contract.  West could balance with 2NT, starting a free-for-all.  The Split
auction is better informed.

LoTrip mini-survey at MIT/DL BC:  P - 2\H; ? ... Pass(2) [opponents play 4\C]
=2, 3\H(1) [we play 3\H] =9, 4\H(2) =5, 2NT[feature](1) =6.    The average

Verdict:  6\DS is a fine contract, but difficult to reach.  The ES auction
shown will get there. Criss-cross RKC (4\C asks) won't get there (only 4\H RKC
over \D, as we play); South needs 4\C to cue the \CA. 

With a three-suited opening, North usually shuts the auction down at 3NT,
after finding club shortness - or on the Quad auction, where a diamond slam
would be played by North.  The key to the hand is the \CA (as opposed to the
\SA), and North's three-suited auctions do not discover it. 

The HiTrip North hears partner bid the magic suit, and might guess to drive:\n
2\D - 2\H; 2NT [long \H] - 3\D; 3\S [short \C] - 4\C [Kickback]; 4\D - 4\S
[RKC \D]; 4NT - 6\DS.\n
(The alternative 4\D control ask gets a less useful 4NT=5 response.)

Verdict:  A poll of mitdlbc-discuss said most standard Souths would jump
raise, even without the \SQ.  With a major suit fit, the \CA improves in
value, so North raises to game. The contract is a lucky one, as the cards lie.
 In general, 4\H looks like the place to be, but not by a wide margin.

Most three-suited auctions don't disclose the possibility of game, and have
been downgraded in the scoring.  The Mini is worst, as a 2NT response would
effectively drive to game opposite any 11-15 hand with spade shortness.  South
on the Split auction could upgrade the hand, not open 2\D, and game would be
reached.

With the 14-16 range of the HiTrip South, North drives to game.

With game opposite 17-19, the HiTrip North inquires with 2\H.  Over 2NT, he
cannot afford to ask, as only spade shortness (the best) allows him to stop in
3\H.  North should assume a jump raise of hearts, as in the ES and UnbalD
auctions, and bid the game.

Verdict:  On the three-suited auctions, North would like to be in game
opposite diamond shortness - or if South has a Midi.  On the lie of the cards
above, East will have no trouble leading his stiff diamond and getting a
couple of ruffs.  West's trump trick means all these game try sequences result
in a negative score.  So reaching 3\S is clearly inferior to 2\S.

GIB and ES, with the natural 1\D opening, keep West out of the bidding.  I'm
not wild about the 3\S bid by North, but it seems right, with a doubleton club
and 10 HCP.  South refuses the game try with what is likely the wrong
shortness.  South may make 3\S with the lead not obvious to West.

The UnbalD auction lets West make a nasty matchpoint 2\D overcall, which tends
to warn off both North and South.  South can expect something like 8 points or
more for this negative double.  South's 2\S limits his hand to 14 HCP,
assuming a 4-card spade suit. So North passes 2\S and reaps a top score.

Verdict:  The heart lead by North, or diamond lead by South and a heart
switch, is nearly automatic against a spade contract.  All that's needed is
one ruff to beat a 5\S contract, assuming North does not duck the \DA.  

If North stays out of the UnbalD auction, East will have little choice but to
raise to game, because South did not offer a natural suit to cue bid - the
same reason West has no Michaels cue bid.  So UnbalD has an advantage, whether
or not North makes the off-shape 3\C response.

1=4=4=4 is a tough shape for natural bidding, and the hand is too weak for a
LoTrip opening.  Passing as South works out well, as most Norths will open 3\C
in third seat.  It seems obvious to bounce to 5\C, but GIB stopped short, for
a bottom.  Move the \DK, and 5\C makes.

The 11-point Mini auction is inferior.  First, North must assume club
shortness.  Then he must guess spade shortness, and take the save.  The Split
and Quad auctions work well.

Verdict:  The GIB North went overboard with 3\H and snagged another bottom. 
The ES auction is inferior, because North could decide that 3\H is not merely
competitive - but if South passes 3\C, that will likely end the auction.  The
UnbalD auction is better, because South's 3\H is limited to 14 HCP.

The three-suited openings fare well, as North can easily bid 3\H, with spades
in reserve.  The Split auction seems a tad better, as South knows for sure
that North has both majors.  The LoTrip and Quad Norths must inquire, as they
are interested in game opposite a midi.

Quad:  2\C - 2\H; 2\S [maxi] - 2NT; 3\S [short \C] - 4\HN  =6

Verdict:  Notrump works well, only because clubs are stopped (which neither
partner can know) and diamonds run (as the cards lie).  At the same time, a
5-0 split dooms 4\H, the proper contract.  Note that West should not double
4\H, because he cannot set 5\D - and should not save, of course, with 5 decent
trumps - and East should respect that.

The LoTrip auction essentially lands in game because North has red suits and
South has 18-20 HCP.  (Cheapening all the ranges by a point would increase
this risk.)  The HiTrip, Quad, ES and UnbalD openings are superior, because
they could stop in 3\D, 3\H or lower, if North were broke.

With all those primes and the \CK, the standard and UnbalD Souths are correct
to drive to game. \n
Similarly, the Blue South should upgrade those primes to 19-20, even if the
\CK only counts 1.

The GIB East could have tried 2NT, instead of 2\S, but the UnbalD East could
not, after the artificial 1\C opening.

Verdict:  Almost a flat board.  I don't like GIB's auction, but South does

enough to drive to game, even if North had planned on rebidding a non-forcing
3\C.  The ES South had the same option, but chose to keep both majors in play.

The LoTrip and Quad auctions work well.  In contrast, the other Norths decided
to drive to game on 12 HCP and a possible misfit.  It worked out well on this
deal.

Verdict:  The natural 1\D opening used by GIB and ES prevents the unusual NT
overcall and wins the board.  The LoTrip and Quad auctions hold an average
result over the long haul, as 5\S mostly depends on the diamond finesse.

Miles recommends negative free bids in competition after the artificial 1\C
opening of UnbalD.  Does this North hand qualify?  An off-shape negative
double might get to 5\H.  Passing does not seem appropriate.  Using methods
that Mark and I tried briefly, the auction would have been: 1\C - (2\C) - X
[6-9 HCP] - 5\CW; P - (P) - X, never finding the spade fit.

In an accident of the auction, the HiTrip 2NT rebid avoids West's 2NT

Verdict:  The LoTrip and Quad auctions could have had trouble, playing 3\D or
3\S in a 4-3 fit.  In both systems, North has game opposite a midi, and thus
must inquire.  5\C could be on, opposite diamond shortness (switch South's
pointy suits), which was never ruled out by either auction.  Remember that 4\C
is always artificial on inquiry auctions, so North cannot risk asking over 2NT
and discovering spade shortness at 3\H.

In contrast, the UnbalD auction worked quite well, since North has values for
the 3-level.  The Mini auction would, of course, miss a likely game, when
South has a 15-point maximum.  Otherwise, the Mini and Split auctions are
equivalent.

The natural 1\D opening does just fine, although North never finds out about
the spade shortness.

Verdict:  It will take good judgement for North-South to stop in 3\S, but it's
definitely possible.  The Mini North has promised at least invitational
values, so may choose to try 3\S.  North-South have 25 HCP and 7 top tricks.  
Adding a round Q to South only makes 3NT reasonable, so North is right to want
a maximum from an 11-15 South. 3\S is easier for the UnbalD North, opposite
the usual 11-14 South.

Often when it's right to play the Moysian fit, it's sufficient to find that
strain, and not necessary to push to game.  With 3NT failing by a trick or
two, this is one of those hands.  When the ES North offers 3\S, South has an
easy pass.  The contract is cold on a dummy reversal.

The Quad North only wants to play 3NT if South has a short spade.  This
inventive pass or correct 3\S bid should do the job.

The likely spade lead on the GIB (and natural LoTrip) auctions makes 3NT a
great spot.

Verdict:  GIB surely got it right, bidding 1\S over that reopening double.
Think about it:  even if this is a 3-3 fit, 1\S will probably come home.  1\S
prevents the negative score on this layout.

The obvious choice is 1NT, expecting to make 7-8 tricks opposite a passed hand
(but not this time).  A diamond lead, accurate cashing, and a trump promotion
will defeat 1\H.  Passing the double would be unusual, and likely to lose.

If you played Split with a 10-13 minimum, the auction should go:  2\D - (2\H)
- X [cards] - 2\SS

Verdict:  The creative Mini auction is effective, but may elude the
inexperienced at the table.  The invitational 3\S should have play when there
is no game.  Assuming 3NT by South would show a  stiff honor, or perhaps bad
spades, South gets to a double dummy good contract - now just make it.  If
North bids 3NT himself and finds South with a K or Q less, 3NT will be
hopeless.  

The Split pair has the natural, invitational 2NT, a mixed blessing.  Since
North denies a major, he is likely to have diamonds stopped, but it would be
nice to know.  The LoTrip North essentially commits to game, opposite 12-14,
fit or no.

The HiTrip opening promises at least 14 HCP, providing North with the
confidence needed to drive to 3NT.  Similarly, the 1-level openings provide
ample space to feel comfortable with the 26-point 3NT.

Verdict:  GIB deserves to play 2\C with a laydown game.  3NT is not great, but
is a normal contract.  

The UnbalD 2\D rebid is forcing for one round, so South would be in this one
less one of the Qs in the North hand, a poor prospect, and a nasty auction. 
The system needs a 3-suited opening.

The three-suited opening and ES auctions all show at least 18 HCP, and North
is correct to try 3NT, with 26+ between the two hands.  North never finds out
about South's spade honor, so declaring in North would be slightly better.

Verdict:  The three-suited openings all reach 3\C cleanly, although the
meanings of the bids take two basic forms.  If you think it over, no matter
how opener responds on a minimum range, within the system in use, these
auctions will lead to an 8-card minor suit fit.  If opener shows a midi,
responder can still bid 3\C, pass or correct.  Responder also has the option
with all these systems of playing 2\S (or 3 of a minor, if a misfit).  Neither
black suit contract will do well  on a spade lead, but the spade contract may
escape that.

The one-level openings should get to only 2\C, likely a significant difference
only at matchpoints.  A matchpoint 1\S overcall should not make much
difference.  GIB overbid.

Verdict:  All the systems should get to 4\H, but there are differences.  The
Mini North has a lucky card location, where the \SA still has value, even with
the worth possible (3\S) bid from opener.  Switch the \SA and \CK, and North
would only want to be in game opposite heart shortness.  The alternative 4\D
response (4-4 or longer in the majors) would be equivalent in this case, but
would facilitate slamming on a bigger hand.

The LoTrip and Quad Norths have it all.  When South shows short spades, all
honors are still working, and 4\H is a reasonable shot.  Swap the \SA and \CK,
and North stops in 3\H.  The Split North has an equivalent invitational 3\H
bid available over opener's 3\C showing spade shortness:  he could simply have
signed off in hearts, rather than inquiring with 2NT.

The GIB auction is standard, although West's vulnerable overcall is pretty
sick.

Verdict:  The last two GIB bids (starting with 3\S) before the double were out
of control.

The UnbalD West bids aggressively to 3\H, in the face of the strong, limited
1\C opening.  Most of the other East-West pairs have to be pushed to 3\H. 
This is a hand that could go many ways.

The HiTrip and LoTrip auctions win this time, because West has no reasonable
escape from East's 3\C bid.  This time, East might do better to wait and back
in with 3\C, but you can see how risky that would be.  When North responds in
hearts, East's holding in that suit should keep him out of the auction.

Verdict:  This deal shows a curious preemptive effect of the artificial
diamond openings, even 1\D.  After a 1\C opening, West can settle peacefully
in 2\D, so long as he does not make an awful 1\S rebid.  After an artificial
1\D opening, West will land in 3\D.  After a Quad 2\C opening, 3\D will be
reached, unless East decides to pass this misfit with suits breaking badly. 
After a 3-suited 2\D opening, West must start at 3\D, and may be lucky to end
there.

Those in 3\D might be doubled at matchpoints if South had extras, with North
converting.

Verdict:  Only South has the high cards approaching an opening hand.  I reckon
this hand quite not good enough, even with both majors and three quick tricks,
playing ES or UnbalD.  A 3-suited opening would result in a contract of 2\S
(or 2\H).  While these contracts can be made double-dummy, it's not obvious
how to do so, even looking at all the hands.

An UnbalD 1\D opening, often made with 11 HCP, might result in 2\CS, resulting
in a lower score.

Quad:  2\C - (2\D) - 2NT [game try]  - (P); 3\C [mini, short \D] - (3\D) -
3\HN  =7

Verdict:  With a likely loser in each suit, and other things that could go
wrong, a major suit game is against the odds.  As dealt, the lie of the cards
permits picking up both black suits, and all suits split evenly.

The GIB West should have been doubled in 4\D, for a bottom.  East's flat
5-3-3-2 is too poor for the 4-level.  

The three-suited openings should effectively keep East out of the bidding. 
North doubles to show the balance of power, and South takes out cheaply with
shortness.  An alternative for North would be to compete with 3\H, promising
at least two places to play.  The Quad North is stuck, not willing to play
only 2\D doubled, and makes the underbid of 2\H, showing at least two places
to play.  It works out fine, in this case.

In the UnbalD auction, South bids spades first, keeping hearts in reserve for
competition at the 3-level, since his distribution not fully known.
