SPLINTER RESPONSES TO A MAJOR OPENING
A double jump response to an opening of 1H or 1S is a splinter bid:
Opener Responder
1H 3S/4C/4D
or: 1S 4C/4D/4H
The requirements are:
-- A singleton in the splinter suit--not a void
-- Four trumps to the queen, or better
-- Game-going strength, high cards in three suits
A splinter response has a range of 13-15 points or so, counting
distribution. That is just a rough guide, because some hands in
this range do not qualify. Examples of a 4D response to a 1S
opening:
SKJ62 H-Q107 D-8 C-AQ863 (a maximum)
SQ1074 H-K83 D-4 C-AJ762 (a minimum)
But with S-AKJ3 H-Q83 D-6 C-108762, start with a 2C (or 2H!)
response. Too much of the total strength is in the trump suit.
The splinter bid tends to deny a biddable suit in the other major,
but responder may violate this rule if she is quite sure that
opener's suit is the right trump suit.
When responder's strength outside of the trump suit is concentrated
in one suit, it is better to bid that suit rather than make a
splinter bid. With S-AQ75 H-983 D-AQ872 C-4, a 2D response is
better. Splinter responses imply strength in three suits. If opener
rebids 2S, then you can splinter with 4C.
Splinter Bids in Competition
Splinter bids are used over a takeout double or overcall, with no
change in meaning. After an overcall, single jump cue bids are
splinter bids, as are any jumps to 4C or 4D:
South West North
1H 2D 4C/4D - splinter bid
3S - natural
Note that the jump to 3S is a single jump in a major, so it is not
a splinter bid. A double jump to 4H in response to 1S is a splin-
ter, as if the overcall had not occurred, but a single jump to 4H
is natural.
