Overcall
In contract bridge, an overcall is a bid made after an opening bid has been made by an opponent; the term refers only to the first such bid. A direct overcall is a bid made directly over the opening bid by right-hand opponent; an overcall in the 'last seat' is referred to as a balancing...

Single suiter
In contract bridge, a single suiter is a hand containing at least six cards in one suit and with all other suits being at least two cards shorter than this longest suit. Many hand patterns can be classified as single suiters. Typical examples are 6-3-2-2, 6-3-3-1 and 7-3-2-1...

s), or conventional (as explained below).

The convention was published in Bridge Magazine IMP.

CoCa overcalls

dbl = A) 4-card spades plus a longer suit, or B) 6-card spades

2 = A) 4-card hearts plus a longer suit, or B) 6-card hearts

2 = 4-4 majors

2 = 5-card plus minor suit

2 = 5-card plus minor suit

The canapé structure of the dbl/2 CoCa bids (with a rebid in another suit denoting a longer suit) is what lends the convention its name.

Responses

Following the CoCa double, the partner of the doubler responds as follows:

(1NT) - dbl - (pass) - ??
pass = hand suitable for defense (usually denies spades)

2 = pass-or-correct bid

, denies 4-card spades (doubler to pass or bid longer suit)

2 = pass-or-correct bid, denies 4-card spades, hand suitable for conversion to 3 (doubler to pass or bid longer suit)

2 = pass-or-correct bid, denies 4-card spades, hand suitable for conversion to 3/ (doubler to pass or bid longer suit)

2 = spade fit


Similar responses apply to a 2 overcall:

(1NT) - 2 - (pass) - ??
Pass = to play

2 = pass-or-correct bid, denies 4-card hearts (doubler to pass or bid longer suit)

2 = heart fit

2 = to play

Advantages/disadvantages

CoCa renders all unbalanced hands with a major suit biddable. Claimed advantage of CoCa over other conventional defenses to 1NT openings, is that the first CoCa bid establishes at least one major anchorsuit. Obviously, this advantage can turn into a disadvantage in cases knowledge of this anchor suit helps the opponents with a key decision during play.

Furthermore, for nine out of the twelve frequently occurring 5-4 two suiter
Two suiter
In contract bridge, a two suiter is a hand containing cards mostly from two of the four suits. Traditionally a hand is considered a two suiter if it contains at least ten cards in two suits, with the two suits not differing in length by more than one card. Depending on suit quality and partnership...

s, the structure of the CoCa-overcalls allows the partnership to sign-off in the longer suit at the two level. Moreover, for five of these 5-4 hands, also the 4-card is known to partner before the bidding goes beyond that suit at the two-level. As a result, the treatment minimises the chance of ending up in a Moysian (4-3) fit whilst a better (5-3) fit is available.

DONT
DONT is a conventional overcall against an opposing 1NT opening bid. DONT, an acronym for Disturb Opponents' Notrump, was designed by Marty A.

, using CoCa carries the consequence of losing the penalty double over opponent's 1NT. Although this is sometimes seen as a loss, the inventor of the Lionel convention, Lionel Wright, argues that this loss turns into an advantage as it opens the possibility to defend 1NT doubled with split points between both defending partners. As a balanced holding of the majority of points is far more likely to occur than holding the majority of points in an imbalanced way, a conventional non-penalty double over 1NT holds the potential of paying-off on many hands. Also, non-penalty doubles are more difficult to deal with than traditional business doubles.
