Mini Splinter - A jump shift or jump
reverse (by opener or responder) to show a 4 card fit, a singleton or
void in the named suit, and 16+ distributional points, and invitational values:
|
1C - 1S;
3D |
3D promises 4
Spades, a singleton or void in Diamonds, and invitational values. |
|
1C - 1S;
3D - 3S |
Responder bids trump at the
lowest level to signoff with minimum values |
|
1C - 1S;
3D - 4S |
Responder bids game with
complementary values |
|
1C - 1S;
3D - ? |
Responder may cuebid a new
suit with additional values or initiate a slam convention with a strong
hand and no wasted values in opener's short suit |
Note: partnership agreements for Mini Splinters - some play opener's jump
forces game.
By definition, opener's Mini Splinter suit must be beneath
responder's suit, allowing responder to signoff in 3H/S with a minimum hand
(6-8 bad points).

novice and intermediate players:
