I love splinters but it seems I have been missing out on a lot of splinter bids. My understanding of splinters are sequences such as
1♥:4♦

1♣:1♥
4♦

Or as a general rule a jump bid ‘above 3 of the trump suit’

Now I see
1♣:1♥
3♦
is considered a splinter, are strong jumps out of fashion?

P:1♠
3♣ is a mini splinter?


Auto splinters/self splinters?

What is the average BBO player playing?

I play 1x-1y-3z, where z is a higher ranking suit than x, as a splinter. This is because 1x-1y-2z is already a reverse, 100% forcing.

So in your example, 1♣-1♥-3♦ is a splinter because 1♣-1♥-2♦ is already a forcing sequence.

I would play P-1♠-3♣ as a fit jump unless discussed as something else, mostly because my drury structure allows responder to show shortness eventually anyway.

edited out some garbage.

hi,

I've been trying to test the Karen Walker aproach

Jump Reverse Rebids describe a minimum 6-5 hand that has greater length in the lower-ranking suit.

But must confess that I still have to find the hand to do it

Hi,

I have no idea, what the av. BBO player plays, I would make
a clear splinter bid, but I would be prepared to say sry.

I would like to rephrase your definition for splinter:

If a suit bid one level below the actual bid would be natural
and (game) forcing, than the bid is a splinter.
The bid is also a splinter, if the bid one level below is a
splinter.

If you look at your first two examples, those examples fit,
if you require the bid below to be natural and gameforcing.
The 3rd would fit with the more broader definition, i.e. the
definition, which requires only that the bid below is natural
and forcing.

If the 3C in your 3rd example is a splinter or a game forcing
jump shift, is a matter of partnership agreements,
the sgame forcing jump shift is the classic meaning, but some
say, that a splinter bid is more usefull.

Your last example may or may not be interpreted as a splinter,
since the 3C bidder is a passed hand, a natural 2C bid would not
be forcing, it may not even be natural, if you play Drury.
Assuming we ignore the fact, that the 3C bidder is a passed hand,
yes some play 3C as a splinter.
Others may play, that 3C is a fit jump.

With kind regards

These are the non-competitive bidding sequences I know about which are commonly used as splinters

i) double jump shift over a major

1h - 3s/4c/4d
1s - 4c/4d/4h (The use of 4h here has been known to cause disasters...)

or 1d-1h-4c

ii) jump reverses

1c-1M-3d
1c-1s-3h
1d-1s-3h

(double jump reverses can also be used to show shortage - I use these to show voids - not sure what's 'standard')

iii) double jump in the 4th suit

eg. 1c-1d-1h-3s

iv) some jumps in 2/1 auctions

1h-2c-3d (= 4+ clubs and diamond shortage)

v) double jump shift over 1 minor
1c-3d/3h/3s
1d-3h/3s

vi) also a number play over 1nt followed by a transfer to a mnior then a new suit as shortage (but this is definitely an agreement thing)

Then theres conventional uses

eg.

a) Jacoby 2nt

1M-2nt then 3 new suit shows shortage

1nt-3M shows shortage (this is part of BBO advanced I think)


Splinters can also be shown in competition

i) jump cue of a 2 level overcall

1h-2c(overcall)-4c

ii) jump in a suit shown by a michaels cue bid or unusual nt

eg 1h-2nt(UNt minors)-4c(shortage)

A lot of this depends on style and agreements.

For example, consider 1♣-P-1♠-P-3♦. Many play this as some sort of splinter. Some do that 6-5 business. I actually use this to show a hand with six clubs and three spades and very strong.

Or, P-P-1♠-P-3♣. A Mini-Splinter is workable here, but many use fit-showing jumps here, or even something like Bergen. I am using an approach where 3♣ in this sequence, strangely, shows a maximum pass with clubs and hearts, 5-5.

There are a lot of common splinter situations, and there are a lot of situations where splinters make sense as one option. In that nebulous sequence situation, agreements are important, or not making the bid if there are no agreements.

You mean for hands too strong to bid a forcing reverse?

P:1♠
3♣  is a mini splinter?

Only if you agreed to play them, it is not standard.

Auto splinters/self splinters?

What about them?

Who knows and who cares? Not even sure the average BBO player exists.
