splinter strength

[phil_20686]

So I think its been more or less established that tightly bound splinters work best, and bung the rest of your GF hands into Jacoby type things. You can do a lot with the space after 1M-2N. but space is very limited after a splinter.

 

If you can splinter with a single jumjp (e.g. acol players sometimes play 1M-3m as a splinter) then they can have wider ranges since you have more room.

 

As to the precise range, I play about 9-12. If its too weak the extra space is too valuable for opponents. They get a free t/o double over a splinter, so its less effective than a preemptive raise in preempting, particularly heart splinters. 9-12, 10-12, 10-13, 11-13 are all fine.

I think a splinter gets the message across with this hand. The message is, I have a least 4 trumps, game values, slam may be possible if your values are outside of spades. I will not be unhappy if my partner signs off with 4 hearts. I will be a very happy camper if they continue with 4 clubs. I also would never have a have card trick taking side suit. Partnerships could also use 3NT from opener as either serious or non serious which ever they prefer.

 

This last point, specifically for 1♥-3♠, occurred to me while doing some grocery shopping (a storm is on its way). Probably easiest: Over 3♠ the bid of 4♥ announces that my hand, not much to begin with, has gotten worse. Bidding 3NT over 3♠ announces that there is nothing extra, or maybe just no clearly better call, but at least the hand has not gone down in value as a result of the splinter. Something like that should allow more leeway in the strength of the splinter, although I agree that a somewhat narrow range is still the way to go.

 

Thank you all for your thoughts. I have been playing for a long time but for the last twenty years or so I have not been playing all that frequently and it is good to hear current thinking.,

The hand is 100% a totally normal splinter for me. Indeed what else? I really can't stomach 2C at all.

 

Agree with lowerline that requirements for splinters should be different the more room you take up, but I would prefer the word "purer" rather than stronger. 1S-4H for example should be a much rarer bid than 1S-4C. If instead of 4H I can describe my hand more suitably with jacoby, a LR or a 2/1 I will do so. You might say this is "just bridge" though..

Probably easiest:

I am not sure about your up/down in values approach. Easiest for me is:

 

3NT = slam try

4m = serious slam interest and cue (or asking bid if you play that)

4♥ = no slam interest

 

We had a topic along these line in a previous thread and Justin wrote that he likes to use the third step (3NT) to be able to show first round spade control. Even from this source I am not (yet) convinced but am keeping it in the back of my head to analyse at some stage. If you use my method and the splinter is 3NT instead of 3♠ then this "problem" is not there; instead you get to decide whether 4♠ is going to be RKCB or not, and if not whether it is first round spade control or a general slam try.

 

The more interesting case, in my view, is the middle splinter, 1♠ - 4♦ or 1♥ - 4♣. Most use the in-between bid as a form of Last Train, effectively a slam try but I am considering whether it is not better to use the next 2 steps (4♥+4NT after 1♠ or 4♦+4♠ after 1♥) as cue bids/asking bids instead, even when this means that, for example, RKCB for spades would be 5♣ (Gerber's revenge?).

 

If it turns out that there is a particular advantage for one approach over another here then it could potentially lead to a major benefit since it would be reusable in all splinter auctions, not just first round splinters. Therefore this subject is quite near the top of my "things to analyse" list. Get ready for the book, due out in a webstore near you around 2044.

This approach is consistent with the view that the Splinter itself is not a slam try. When the Splinter range is minimum and narrow, Responder never feels "unsatisfied" when opener merely bids game and is not tempted to bid again.

 

We have one exception: Responder can set trumps via Splinter after which RKC is exclusion RKC. If responder merely wants to set trumps and take over with regular RKC, she uses the J2n or whatever method...even with a singleton somewhere.
