SOMETIMES ON SUNDAY
THE CARE AND FEEDING OF REVERSES

 

by Beverly Kraft -Eric Kokish

 

The subject of reverses has been confounding developing players for decades. Here are some examples: (a) 1-1; 2 (b) 1-1; 2 (c) 1-2; 3. Opener's 3 in (c) is known as a "high reverse" because it raises the bidding to an even higher level. In all these auctions opener's second bid forces his partner to go to the three-level if he prefers opener's first suit. As responder may hold a weak hand, opener must have a good one to risk committing to those heights.

 In the auction below - call it (d) - South's 2
bid is a reverse. Unlike a jump shift, a reverse is not forcing to game but it could be every bit as strong as a jump shift; responder is expected to bid again. Another key feature of opener's reverse is its guarantee of greater length (at least five cards) in his first suit. Opener promises a third bid unless responder makes a bid known to be weak in a playable strain. In mainstream North American bidding, responder's same-suit rebid promises a five-card or longer suit but is not defined as weak (he would, however, jump to 3 with a one-loser suit of at least six cards. It is common to treat responder's raise or simple preferences as forcing (also) and to use 2NT as a conventional signal of weakness, denying as many as five spades. Over responder's neutral 2, opener tries to limit his hand when he can.

As South, what call do you make with each of the following hands?

a)
K2 A AJ32 AJ9863


b)
A K106 KQJ6 KQ1098


c)
AQ3 76 AK6 AK1098


d)
AK 76 KQJ6 KQ1082


e)
AQ 85 AQJ5 AKJ98



a) Three clubs. South shows a near minimum in high cards and a sixth club.

b) Two notrump. Natural, about 17-19 points. South may be 2-2-4-5 but this sequence does not imply a balanced hand.

c) Four spades. Some would open two notrump or rebid two notrump over 1
. For those who avoid such actions with a weak doubleton, 1, then 2 (ostensibly natural) will be just right. When North repeats spades, South's jump raise can be defined as three-card support but no singleton heart. Change the 7 to the 7 so that South is 3-1-4-5, and he would jump to 4 over 2, a "splinter" raise showing heart shortage and true spade support.

d) Three spades. Take away a queen and the South hand would not be worth a reverse (you might open 1NT). As 2
is forcing, South cannot pass. 3 shows exactly a doubleton spade (with at least one honour) and denies a heart guard (else 2NT). 3 sounds nonforcing and so it is.

e) Three hearts. South is not showing a suit of hearts (else 2
over 1). His bid in the fourth suit after reversing shows a hand too strong to limit but with no clear direction. South is too good for a nonforcing 3, as in (d).
