RainBow Series - Lesson VI - 2-suited Overcalls


RainBow Series - Lesson VI



Two Suited Overcalls


				  
	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 FIVE 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:

S- AKQxx
H- Kxxxx
D- xx
C- x
			
	After a 1D opening we have the choice between
1S, intending to rebid the Hearts LATER, and a 
Michaels Overcall of 2D, showing the majors.  Let
us analyze what may happen in both cases.

	If we overcall 1S, 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 2D, showing BOTH majors, and
do not get another chance to bid, partner must GUESS
which major you'd like led.  Hence, overcall 1S here.

	Now let's reverse the majors and reconsider:

S- Kxxxx
H- AKQxx
D- xx
C- x
	
	Here a 1S overcall would only confuse the issue;
we want a HEART led.  Alright, how about a 1H 
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.
1D
1H

-

2S

3H
This may be too high!
	
	Hence, with the second hand, we MUST use the 
2-suited overcall, a Michaels 2D.  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,
HIGHest 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*.

1C

1H

1D

2D
Natural. Not Michaels.
	
	The last example, 1D-P-1H-2D is NOT Michaels 
because Responder did not pass.  2D, then, is NATURAL
when BOTH opponents have bid a different suit--as a 
2H (i.e. 1D-P-1H-2H) bid would be!

	
	       --------  Questions  ----------
			
1.  If you have a 5-5-3-0 hand, void in Opener's
	Clubs, should you Double or make a Michaels
	cuebid of 2C with your 5-5 in the majors?

Hand #1
S- Q10xxx
H- AKJxx
D- xxx
C- void

Hand #2
S- Q10xxx
H- KJxxx
D- KQx
C- void
	

2.  Can I use Michaels with a 5-4 2-suiter?  How
	about a 4-5 2-suiter (i.e. with the 4-carder
	being the higher ranked suit)?
	
3.  After 1S-2S or 1H-2H does Partner know which
	minor I have?
	
4.  Does Michaels apply if they open a weak 2-bid?
	Is 2D-3D Michaels?  2H-3H?  2S-3S?
	
	
	-------  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.

S- xx
H- xx
D- Kxxxx
C- Kxxx
	After 1C-2C-P or 1D-2D-P bid 2H, not 2S,
	since if EITHER of Partner's majors *is*
	longer/stronger, it will be HEARTS.		

	If Partner has cuebid a MAJOR (i.e. 1H-2H or
1S-2S), Advancer can use 2NT to ask for the 
hitherto unspecified minor.

1H
2H
Pass
2NT
"Your minor, pard?"
Pass
3D
--
--
Five or more Diamonds.
	
     In those rare instances where the Michaels
cuebid comes at the 3H or 3S level (e.g. 1S-P-2S-3S) 
a CLUB bid by Advancer shows a preference for the
undisclosed MINOR.   Cuebidder will correct to 
Diamonds if that is Cuebidder's second suit.

1H
Pass
2H
3H
Michaels. Spades and a minor

4C

4D
Five or more Diamonds.
	
	Advancer's strongest action is always a cuebid
of the enemy suit, forcing game.  This may come
immediately (e.g. 1H-2H-P-3H) or after requesting
clarification of the minor via 2NT.  In the latter
case, Overcaller's MINOR is presumed to be trump.

1H
2H

2NT
"Your minor, pard?"

3C

Game force.
	
	In the above example, then, Clubs will be
the presumed trump suit.

	Any jump to the three level (e.g. 1H-2H-P-3S)
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...

1C
2C
Pass
??
3H or 3S invite game here.

1D
2D
Pass
??
3H or 3S invite game here.
	
	...and we can invite game in Spades over 1H-2H-P
by jumping to 3S.  But how do we invite in HEARTS
after 1S-2S-P ?  An immediate 3H bid over partner's
2S Michaels cuebid could be bid on ZERO HCPs with
3+ Hearts.  Bidding 2NT, to ask for the minor, and
THEN 3H 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 4H over 1S-2S-P. :(

	For a solution to this vexing problem--one 
which requires that you discuss this dilemma at 
length with your steady partner--read the article 
on "Lover's Leap" from his humour article on
"The Three Gadgeteers" at Colin's "personal" web site:

http://www.escape.ca/~ksired/bridge.htm
	
	...or the article on "Lebensohl" at Colin's
"tutors" web page at:

http://www.escape.ca/~btreble/leb.htm
	
            -------  Questions  --------
			
1.  After 1C-2C-P should I not 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) ?
	
2.  If ADVANCER invites game opposite the Michaels 
        cuebid (e.g. 1D-2D-P-3S), 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.

          -------  The Unusual 2NT ---------
			
	A jump to 2NT over an opening bid is "Unusual",
promising 5-5 or better in the two lower unbid suits.
Hence:
1C
2NT
--
--
5-5 in the red suits.
1C
Pass
Pass
2NT
5-5 in the red suits.
1D
2NT
--

5-5 in Clubs and Hearts.

5-5 in the minors.
1S
2NT
--
--
5-5 in the minors.
1S
Pass
Pass
2NT
5-5 in the minors.
	
	Again, because of LOTUS, the LOWER of these two
promised suits is likely the stronger.  

	
      -----  Responses to the Unusual 2NT  -----
	  
	For the most part, ADVANCER bids naturally,
choosing the suit and the level.  ADVANCER's only
forcing reply is a cuebid of the enemy suit, which
is usually a move towards 3NT or, once that level
is breeched, slam.


        --------  The Sandwich 1NT  -----------
	
	When BOTH opponents have bid a suit of their
own at the 1-level we have TWO ways to show the
unbid suits:  via a takeout double or a No Trump 
overcall.  Given two ways to show the unbid suits, 
we use the double to show a hand with better HCPs
than distribution:  10+ HCPs and 4-4 or 4-5 in 
the unbid suits.  A 2NT overcall, on the other
hand, shows better distribution than HCPs:  11+ HCPs 
and 5-5 or better in the unbid suits.

	The question that arises is whether a 1NT
bid shows a weak hand with 5-5 in the unbid suits 
or whether it shows 15-18 HCPs in a flat hand.  
The SAYC notes do not make this clear.  However, 
bidding 1NT with 15-18 points after one opponent 
has shown 13+ and the other has shown 6+ points
is suicidal.  Hence, let us treat the 1NT bid
in this instance as 5-5 in the unbid suits and
6-10 HCPs.  This is called the "Sandwich 1NT"
overcall.
1C
Pass
1S
1NT
5-5 in the red suits, 6-10 HCPs.
	
	Again, the Sandwich 1NT is something that you
should clarify with your partner.  When you bid a
Sandwich 1NT, you must ALERT it by hitting the
"ENTER + ALERT" key instead of the "ENTER" button.
Then you must explain it to both opponents as
"Sandwich - 5-5 in the unbids, 6-10 HCPs". 

		
	--------  Responses to the Sandwich 1NT  -----------

	ADVANCER's only forcing response to the Sandwich
1NT is a cuebid of one of the enemy suits.


           ----------  Questions  --------------
		   
1.  Without any prior discussion, should I presume
	that we ARE playing a Sandwich 1NT or that we
	are NOT playing a Sandwich 1NT?
	
2.  If I make a Sandwich or Unusual 2NT, doesn't that
	often mean that if the hand belongs in 3NT it will
	usually be played from the wrong side?

RAINBOW Series

The Rainbow Series, from 10:00 A.M. to 12:30 PST every weekday, is a lecture program on the SAYC system, from Opening Bids all the way through to the conventional aspects of SAYC. Unlike the FireSide and 5th Chair sessions mentioned above, the Rainbow Series is a semi-private lesson program for our students. Nevertheless, you are invited to stop by and "eavesdrop" on the discussion from the Spectator's Loft.

If you have any questions arising from these notes, or about the Rainbow Lesson Series, please do not hesitate to email me at: cpw@escape.ca
