THE SINGLE RAISE
In a Major
This raise is based on support tricks that may be in high cards or
mainly distributional. When you raise 1H to 2H, partner will take
you to have at least S-84 H-Q1072 D-984 C-A752 or S-9653 H-J10653
D-K74 C-3. Just because partner would regard these as minimum hands
for the raise does not mean that raises are never made with weaker
hands. It is the same as with sub-minimum opening bids and
overcalls--you risk misleading partner because good bidding has to
be competitive as well as constructive. Of course, having raised
1S to 2S with a hand like S-K763 H-104 D-J862 C-942, you do not
jump to 4S over a 3D game try rebid by opener, just because the
hand "fits." A sub-minimum becomes only a minimum when the hand
fits, not a maximum.
When RHO overcalls, sub-minimum raises are usually given only at
favorable vulnerability. Over a double, however, sub-minimum raises
are standard procedure.
At the other end of the spectrum are hands that are top-heavy for
a single raise, but present no good alternative. These are the
4-3-3-3 hands with no side suit:
S-KQJ3 H-A42 D-542 C-653
S-AK8 H-QJ7 D-7543 C-862
Just raise 1S to 2S with these hands. The first one is not worth
a limit jump raise to 3S. With the second hand, a game try is just
plain bad bidding. If we subtract a point for poor distribution,
these 10 HCP hands are really just nine-pointers.
Adequate trump support for a raise is nominally J10x or better, but
with good ruffing ability or extra strength in high cards, raises
are sometimes in order with three small cards.
In a Minor
Prefer a 1NT response (6-9 HCP, even over 1C) to a minor suit
raise, if the hand looks suitable for notrump play.
Prefer a major suit response unless the major is weak and the hand
is weak. Raise 1C to 2C holding S-10842 H-42 D-K64 C-K1084, but
respond 1S with S-K1084 H-42 D-K64 C-10842 or S-J842 H-42 C-A54
C-KJ84. Bidding a weak major is preferable to a three-card minor
suit raise, however.
Three-card minor suit raises are sometimes necessary in competi-
tion, but otherwise are rare (and only in diamonds). Raise 1D to
2D with S-5 H-763 D-AQ2 C-J97642. If the minors were reversed and
the opening was 1C, a 1D response would be preferable to 2C (by
far).
