Two-way jumpshift response to 1M opening? Not in competition

Hi all,
I have read with enthusiasm quite a few articles/material on FJS= fitshowing jumpshifts (mixed raise with values in trumps and side suit).

This is suggested especially in competition(helpful to suggest competition or sacrifice based on sidesuit fit).

However, I find it useful even not in competition, at least better than the "generic" mixed raise a la Bergen = 4 cd support, 6/7-9 hcp, but you do not know whether they are useful hcps or not.

However, I have also become more and more fond of SJS= strong Jumpshift, very useful to set the trump suit at a lower level to start investigate slam.

So my question is

1) do you think it may be effective to pllay jumpshifts as 2-way: either a FJS or a SJS. opener responds assuming responder is weak (signs off at 3 if bad hand) or cuebids if he would accepth the FSJ invitation

2) do you think it is effective in a Precision context where you cannot use complicated relays ?


Thanks !!

Playing precision your most valuable weapon is that your 1 and 1 bids are limited. So responder knows what can expect from each side and act accordingly.
With that in mind I think that JumpShifts should be used to obstruct and not as strong bids, when you have a strong hand you can start with a simple 2/1 bid.
The options I like for jumpshifts over 1M in precision are:
- Preemptive or semi-preemptive hands
- INV hands with 4 trumps and shortage in the suit (mini SPL)
- INV hands with 6+ cards in the suit and no support.

I like Fit-Showing jumps only in competition.

I don't know luis, I kind of like this idea. I play 1M-2N as limit raise plus, so I don't need bergen. I am currenlty using the jumpshift as fit jump (anticipating competition as it were)... this two way jumpshift might be interesting inovation for those of us who play fit jumps even without competition. I am going to look into how it might work.

Like any two-way bid it will suffer in competition especially pre-emption.

1 (Pass) 3 (4)
?

Now it will be hard to make a sensible contribution to the auction often if partner might have hearts and might have only clubs.

The idea that you should treat non-competitive auctions as if there was competition is valid however.

In most cases a non-competitive auction is merely an auction that is about to become competitive.

Yes Wayne, actually your consideration was worrying me a bit.

However, I thought that, since I planning to use it in a Precision context, the 1 opener is limited, so there is no risk that the 1M opener has a reverse.
Hence the only times we are going to play a slam is when responder has the battleship, so opener can safely make his choice playing responder for the weak hgand; if he is strong he will push forward .

I was thinking - correct me if wrong thinking - that opener can decide to double or not assuming pard has the weak hand, otherwise pass.
If opener has a hand that would compete at the five level because of values in clubs, he just bid five of the sidesuit fit(clubs here). A plausible agreement may be eve that opener may cuebid if he has a control outside, to show a hand willing to compete if responder has the FJS. may even cuebid.
Now responder will corrrect to hearts if weak, otherwise bid on if he has the SJS hand.

Perhaps I should add that with SJS I mean a hand which MUST meet at least one of these criteria:
- distributional reverse (at most 5 losers) , one suiter with at most 1 loser in a self sufficient trump suit;
- 18 hcp with a decent 5 bagger suit (3 of top 5 honors)

A hand with just an opening hand with a fair suit will not qualify if not agreeing with the above mentioned criteria.
Therefore, if the responder is strong, it seems relatively safe to bid on even if opener does not bid after the preempt.

I play it as a minisplinter, 4+ trump and 6-9 HCP with singleton in bid suit.
Have played that for while now, and it really suits my system.
