A Bidding Principal

//A Bidding Principal

At IMPs, neither side vulnerable, you hold as North:

North
S Q J 8 5 3
H 8 7 2
D Q
C J 9 8 7
WestNorthEastSouth
PassPass2C
Pass2D3H4C
Pass?

What is your call?


If I were asked what principle good bidders adhere to most closely, I might reply that they seldom neglect to show support for their partner’s suit. Suppose you hold:

S A 7 5
H Q 10 5
D Q J 9 4
C A K 5

You open 1NT and your partner responds 3S, natural and forcing. A mastermind bids 3NT because of his balanced pattern; a disciplined player raises to 4S — what his partner wants him to do with three card support.

S A Q 7
H K 7 5
D A K 6 5
C K 7 3

You open 1D, your partner responds 1S, you jump to 2NT and he tries 3H.Agreeing spades is correct, of course, but since partner has promised five or more spades, your values are slammish and your support is excellent, jump to 4S.

S 8
H K J 5
D A Q 6 4 3
C Q 10 6 4

You open 1D and partner responds 1H. Raise to 2H. Auctions are easier when a trump suit is set quickly. If instead you rebid 2C and partner returns to 2D, jumps to 3D (invitational) or bids 2NT, your hand won’t be strong enough to bid again, and you may miss a heart fit. Moreover, the opponents may be about to compete in spades, and unless you support the hearts now, you may never have a convenient chance.


When I watched the deal below in a strong IMP game on OKbridge, North/South missed a laydown grand slam and conducted a contentious post mortem.

Many North/Souths reached 7C. At some tables they had a smooth ride when East/West stayed out of the auction:

NorthSouth
2C
2D3C
4C/5C7C

Other North/Souths achieved odd results. At three tables the contract was6S by North, making seven when East led his singleton diamond. Three North/Souths halted at 5C on auctions you don’t want to know about. One West pulled off a “striped tail ape” double of 6C. North/South neglected to redouble and scored only +1740, but they still gained heavily against par since a few East/Wests saved at 7H for minus 800.

North/Souths who stopped at 6C usually had to contend with interference. East often bid hearts, and at some tables West jacked the auction up to 6Hright away. When West displayed less enterprise, North/South often reached7C and were usually allowed to play there.

This was the auction at the table I watched:

WestNorthEastSouth
PassPass2C
Pass2D3H4C
Pass4SPass5D
Pass6CAll pass

The bid that triggered the discussion after South claimed 13 tricks was North’s 4S.

South: “You had good club support. Why didn’t you raise?”North: “Because I’m not a genius. You could have had a spade fit and a more balanced hand. How can we get to spades if I don’t bid them? You had all the controls, including a heart control.”

North’s argument left me cold. In a crowded slam auction at IMPs, North’s duty was to confirm a fit. If he had raised to 5C, South might have tried 7C.But as North actually bid, he could have held:

S J 9 6 4 3 2
H 8 7 6
D 8 7
C 8 7

When in doubt, raise. But you should seldom be in doubt.
