Splinter raises

The splinter bid is a useful addition to any pairs’ bidding arsenal. It is a

specialized type of raise that sometimes allows a partnership to bid a game or slam that might otherwise be missed.

A splinter raise is an unusual jump that shows four-card or longer support for the last bid suit, game-going values and shortness (a singleton or void) in the suit in which the jump occurred. For example:

Opener Responder

1H 4C

Responder shows at least four hearts, opening values (approximately; more on this later) and club shortness.

How can you tell which jumps are splinters? They’re usually defined as any new-suit response beyond a double jump. That means that after a 1H opening, 3S, 4C and 4D are all splinter raises, each showing a different singleton or void. After a 1S opening, 4C, 4D and 4H are all splinter bids.

Why are these bids useful? Let’s look at an example:

Opener Responder

S A K 6 5 4 S Q 10 9 8 7

H K Q 6 H A 5 4 2

D 8 6 2 D 5

C A 6 C K Q J

After opener begins with 1S, responder bids 4D. From opener’s point of view, this is good news. She knows that her partner has at most one diamond, making it safe to explore for slam. Why? Opener doesn’t have to worry about the three low diamonds in her hand.

Whether opener uses Blackwood or cuebids, 6S is easy to reach and almost certain to succeed. Notice that the partnership has a combined total of only 28 points, far less than the textbook 33 points suggested for bidding a small slam. If responder had splintered in a different suit (hearts, for example) opener should take a more pessimistic view of things and settle for game only.

How strong does responder need to be to make a splinter bid? Partnerships may, of course, define them as they please, but many players have found that restricting responder to 13 to 15 points (which includes distribution) makes it easier for opener to know what to do. With a weaker hand, other types of raises are available to responder. The same is true for stronger hands. Opener may make a splinter bid as well. Here’s an example:

Opener Responder

S A J 6 5 S K Q 7 4 3

H 9 H 8 7 6

D K Q J 4 D 9 3 2

C A Q 10 2 C J 4
