Rainbow Lesson #6: Two-Suited Overcalls
Preamble
______
The trick-taking potential of any 5-5 (or better)
2-suiter increases dramatically if Partner can support
either or both of our suits. In fact, we should bid
very aggressively with such a fit; if the contract
does not make it is most likely a good sacrifice.
______
The ability to show 2 suits quickly can be a
very useful tool in locating such fits.
LOTUS
______
The question arises, though, whether we should
bid these two suits naturally, starting with the
higher of the two 5+ card suits (according to the
High Five Rule), or use the 2-suited overcall (be
it Michaels, an Unusual 2NT or a "Sandwich" 1NT in
some cases) to show them immediately.
______
Consider this hand:
| Overcaller |
AKQxx |
Kxxxx |
xx |
x |
______
After a 1 opening we have the choice between
1 , intending to rebid the Hearts later, and a
Michaels Overcall of 2 , showing the majors. Let
us analyze what may happen in both cases.
______
If we overcall 1 , we may or may not be able
to bid Hearts later--although this is most true
when the opponents are strong and we would likely
not want to bid Hearts at that level. But, assuming
we do not get another chance to bid, which major
would we want lead? Right, Spades. If we make
a Michaels cuebid of 2 , showing both majors, and
do not get another chance to bid, Partner must guess
which major you'd like led. Hence, overcall 1 here.
______
Now let's reverse the majors and reconsider:
| Overcaller |
Kxxxx |
AKQxx |
xx |
x |
______
Here a 1 overcall would only confuse the issue;
we want a Heart led. Alright, how about a 1
overcall, then? This would be awkward even if the
enemy does not jump to game, since a Spade rebid
by us would be a reverse, forcing Partner up another
level in order to show a preference for our first
bid suit, Hearts.

______
Hence, with the second hand, we must use the
2-suited overcall, a Michaels 2 . It follows, then,
that using a 2-suited overcall strongly suggests
that the lower ranked suit is the superior of the
two suits promised (since, if the higher ranked suit
were stronger we might bid our suits naturally,
higher suit first). This tendency is called "LOTUS":
Lower Of Two Usually Stronger, and applies whenever
we use any 2-suited overcall.
Questions
| #1 |
Is LOTUS a convention? |
| #2 |
Do we have to alert our 2-suited overcalls if we play LOTUS? |
Michaels
______
Any cuebid of Opener'S suit in direct or balancing
(i.e. if Responder Passes Opener's opening suit bid)
seat is a Michaels overcall, showing 8+ (10+ if
vulnerable) HCPs, a 5-5 (or better) 2-suiter,
including 5+ cards in any unbid major if the opponents
have bid only one suit and if not in the passout seat.

The last example, 1 -P-1H-2 is not Michaels
because the enemy bid two suits. 2 , then, is natural
when both opponents have bid a different suit--as a
2 (i.e. 1 -P-1 -2 ) bid would have been.
Questions

If you have a 5=5=3=0 hand, void in Opener's
Clubs, should you bid 1 , 1 , Double or make a Michaels
cuebid of 2 ? |

Does Michaels apply if they open a weak 2-bid? Is 2 -3 Michaels? 2 -3 ? 2 -3 ?

Replying to a Michaels Cuebid
______
Without a promising hand, Advancer (i.e. Michaels
Overcaller's partner) will choose between the two
suits promised. Thanks to LOTUS, with an equal
holding in both of Overcaller's suits, Advancer
will know to prefer the lower ranked suit.
After 1 -2 -P or 1 -2 -P bid 2 , not 2 ,
since if either of Partner's majors is
longer/stronger, it will be Hearts.
|
______
If Partner has cuebid a major (i.e. 1 -2 or
1 -2 ), Advancer can use 2NT to ask for the
hitherto unspecified minor.

In those rare instances where the Michaels

a Club bid by Advancer shows a preference for the
undisclosed minor. Cuebidder will correct to
Diamonds if that is Cuebidder's second suit.

______
Advancer's strongest action is always a cuebid
of the enemy suit, forcing game. This may come
immediately (e.g. 1 -2 -P-3 ) or after requesting
clarification of the minor via 2NT. In the latter
case, Overcaller's minor is presumed to be trump.

______
Any jump to the three level (e.g. 1 -2 -P-3 )
is invitational, on 10-14 points. This, however,
exposes one of the inadequacies of standard
Michaels. We can invite in either major over
a cuebid of a minor...

______
...and we can invite game in Spades over 1 -2 -P
by jumping to 3 . But how do we invite in Hearts
after 1 -2 -P ? An immediate 3H bid over partner's
2 Michaels cuebid could be bid on zero HCPs with
3+ Hearts. Bidding 2NT, to ask for the minor, and
then 3 would not invite, since it might show a
weak hand with 2 Hearts that was hoping Overcaller
had the other minor (say, 5-2-5-1).
______
Standard praxis offers no solution to the
problem of distinguishing a 0-9 point hand, with
no interest in a Heart game, from a 10-14 point
hand that might like to invite to 4 over 1 -2 -P.
______
For a solution to this vexing problem--one
which requires that you discuss this dilemma at
length with your steady partner--use 3 as an invite
to 4 , since with a bad hand with long Diamonds you
and bid 2NT and rebid 3D over Partner's expected 3
rebid. The 3 invite is called "Lover's Leap", since
it involves a bid of three Diamonds to invite a jump
to four Hearts.
Questions
| #7 |
After 1 -2 -P should I jump to 3-of-a-major
anytime I have 4-card support, according to the
Law of Total Tricks (which states that in
competitive and pre-emptive auctions we should
be willing to bid one trick for every trump we
have)? |
| #8 |
If Advancer invites game opposite the Michaels
cuebid (e.g. 1 -2 -P-3 ), what kind of strength
does Overcaller need to have to accept? Assume
that you play that Michaels cuebids show either
strong or weak hands only (as many still do) here? |
