TWO-FOUR-ONE
A jump takeout by a passed hand is played many ways: preemptive
bid, strong suit in a good hand, side suit game try with good
support for opener, etc. With both opponents passing, the
preemptive usage is not worth much, and the one-suited good hand
could usually be shown with a weak two bid. Even if not, a minimum
response is unlikely to hurt. The side suit game try is valuable
after a major suit opening, but there should be a better role for
the jump takeout of a minor.
A passed hand often has a difficult decision when partner opens a
minor. Especially tough are the strong hands that include four
cards in one or both majors, plus either good support for opener's
suit or good notrump prospects. If you bid the major, opener may
pass with poor support. If you have good support for his minor and
he rebids 1NT, should you raise notrump or jump to three of his
suit? Responding 2NT with the notrump hand may lose a major suit
fit if opener has to pass. To solve these problems, we can use a
conventional jump takeout at the two level, called 2-4-1.
Jump Takeout to Two of a Major
A passed hand's jump takeout of a minor opening to two of a major
shows a four-card suit, a game-invitational hand, and at least four
cards in opener's minor. That's two bids for the price of one
(2-4-1). A light opener can pass with four-card support, bid 2NT,
or retreat to three of his minor. He can also bid 2 over 2
(responder could have both majors), but that has to be forcing.
With a good hand opener can raise, force with a new suit (or a jump
in his first suit), or bid game. A raise is not forcing, so a jump
raise is stronger. Having shown support for opener's minor,
responder is free to bid something else after a force.
A raise is not forcing, so a jump to game is stronger:
Opener Responder (a passed hand)
1 2 - four hearts, not forcing
2 - forcing, but may be weak
3 - forcing, full opener
3 - sign-off, weak
3 - invitational
3/4 - splinter, good hearts
4 - invitational
4 - stronger raise
Opener's 4 rebid implies that he needs top cards rather than
secondary strength for game.
The jump may be made with two four-card majors in a 4-4-4-1 or
4-4-5-0 hand. A jump to 2 gives opener room to bid 2 if he has
four spades. A jump to 2 therefore denies four hearts.
Do not use 2-4-1 if you can pass a 1NT rebid. If partner opens 1
in third or fourth seat, just bid 1 with KJ32 Q4 876 A976,
since you are not too strong to pass a 1NT rebid. Why take a chance
on getting too high? Similarly, with a strong major and weak four-
card support for opener's minor, just bid one of the major. Respond
1 to 1 with J73 AKJ2 Q4 10842. You don't mind playing hearts
opposite poor support. Better to play 1 making one than 3 or 2NT
down one. If opener rebids 1NT you will have to bid 2NT, suppress-
ing the club support, but so what? This is a good notrump hand.
Two-Four-One is not used in competition.
The complete text of TWO-FOUR-ONE comprises three single-spaced
pages. It includes another 2-4-1 bid: a 2 response to a 1
opening.
TWO-FOUR-ONE was published in The Bulletin of the ACBL, May 1994.
