Splinter raises : Examples
Ex.1 Bidding : 1♠ - 4♠      
Opener
A Q J 10 7
5 3
8 4 2
A K 5
  Responder
K 9 8 3
A 9 7 2
9
10 9 7 4


This type of Response hand usually counts 8 losers. Because of its shape and abundance of trumps you may deduct 1 loser of the total.
The singleton must be a small card, so that the Honour cards are in the other suits.

With this kind of Responder hand (6- 10 HCP, 4+ trumps plus a singleton or void, no singleton Honour) a Game contract is feasible with around 18-20 HCP ! The Response hand has 8 or 8½ losers.


Ex.2           Bidding : 1♠ - 4♥ - 4NT - 5♥ - 6♠
Opener
- K Q J 4 3
- 8 7 4 2
- A Q J
- 6
  Responder
- A 10 8 5
- 6
- K 9 5 2
- A 9 4 3

With 11+ HCP, 4+ trumps and a void or singleton Responder makes a double jump-shift to his void or singleton suit. This is called a Splinter raise.   4NT is Blackwood.

With this kind of Responder hand (11+ HCP, 4+ trumps plus a singleton or void, no singleton Honour) a Slam contract is feasible with around 25-28 HCP ! (or even less when Opener has an unbalanced hand too) A Splinter Responder hand has 7 or less losers.


Ex.3           Bidding : 1♠ - 4♦ - 4♠
Opener
- K Q J 4 3
- 8 7 4 2
- A Q J
- 6
  Responder
- A 10 8 5
- K 9 5 2
- 6
- A 9 4 3

Opener should not have Honour cards in Responder's Splinter suit, for those high cards will be wasted. However a lone Ace (A x x (x) ) is permissible.


Ex.4                       Bidding : 1♠ - 2♥ - 4♦ - 5♦ - 6♥
Opener
- A J 10 6 4
- K 10 8 5
- 6
- A Q J
  Responder
- 9 2
- A J 9 7 4
- A 9 5 2
- K 6

Opener too can make a Splinter raise with 4+ trumps in Responder's suit and a singleton or void, if Opener considers a Slam contract may be possible.
When Responder's first bid at the 2-level is forcing for one round the Splinter raise may be a single jump-shift, as is the case here.

Responder's bid of 5♦ is a Cue bid showing the A♦


Ex.5 Bidding : 1♣ - 3♠ - 3NT
Opener
- K Q J
- Q 10 7
- 8 4
- A J 6 4 2
  Responder
- 4
- A 9 3
- K Q 7 3
- K Q 10 9 7

You can also bid a Splinter raise after a minor suit opening. In such cases the Splinter is usually at the 3-level and conveys the message : "Partner, if you have this suit covered, bid 3NT."
