Hi,

I am learning a little about strong jump shifts or perhaps more as to when NOT to make sjs’s.
I am following Soloways jump shift recommendations:

After partner's opening bid of one of a suit, a jump shift shows 17-18 HCP, and is made on three types of hands:

a. hands containing good support for partner
b. one-suited hands
c. semi-balanced hands

Could someone please post examples of the 3 hand types that are suitable for a sjs.

I think that Justin has provide a reasonable set of example hands:
I'll throw in three more that are potentially a bit more controversial:

Assume a 1♣ opening by partner:

Hand type A: "Good support for partner"

♠ AQJT6
♥ K4
♦ 56
♣ KQ52

Hand type B: "One suited hands"

♠ KQJ9765
♥ 8
♦ A52
♣ QT

Hand type C: "Balanced hands"

♠ KQT52
♥ AK
♦ T542
♣ K3

Just make sure you are in tune with pard. Playing 2/1 with a new pard I amde a Strong Jump Shift, only to have it alerted as a Weak Jump Shift and I was passed out in 2 Spades, making 6. Also keep in mind how you will identify what type of SJS pard is making.

In Mike Lawrences 2/1 system he uses a similar Strong Jump Shift, but has modified it as follows;

There are 3 types:
Solid suit,
Good 6 card suit plus 18-19,
Good suit and good fit for pard

The HCP and shape vary between these 3. SJF ALWAYS intend to the final contract to be: your suit, pards suit, or NT. Therefore strong 2 suiters may not jump! And don’t show a new suit without a great reason.

Example:
AKQTx AKQTx xQx x You must bid 1 Spade over 1 Club, not 2 Spades.
1C – 2S – 2NT – 3H => shows a heart stiff and 4+ clubs!!!

1. Solid Suit: 13+ HCP AKQJxx or AKQxxxx, but NOT AKQTxx. Must be self sustaining.
Jump shift, and rebid your suit.
1C – 2H – 2NT – 3H = solid suit strong jump shift
1D – 2H - 2NT – 4C = self-splinter in Clubs

2. Good 6 card suit: 18-19 HCP
Jump shift and bid 3NT.
a) 2 of top 3 honors
b ) stoppers in unbid suits
c) 18 – 19 HCP
d) No singlton/void
1C – 2H – 2NT – 3NT = good 6 card suit with HCP SJS

3. Good suit & Good fit: Can be 10-11 HCP (unbalanced 5521), but usually more 14+ (balanced 5422)
Jump shift and rebid pards suit.
1C – 2S – 2NT – 3C
1C – 2S – 2NT – 3D [Splinter] – new suit shows 5-4 and stiff
1C – 2H – 2S – 3S [Splinter]
1C – 2H – 3H – 3S (Ambiguous) Solid Suit and cue bid OR Fit and singleton? (Rare)

When responding to a SJS show:
a) Support for partners suit
b ) Original suit if strong
c) Concentration of strength/honors (AKJ not Q9786)
d) 2NT (least important)

These are indeed a bit controversial, but as usual, it is more important that you and partner agree which hands qualify and which don't.

I think that it is very nice if you can make a SJS with hand A. This is an excellent way to describe your hand.

I think that hand B is too light, even though the suit is good enough. But once again, if you and partner agree that this is the hand partner will expect, then that's fine.

With a balanced hand you should agree exactly how good a SJS followed by a notrump bid is. I think that 17-19 is a sensible range. So hand C would be too light for me.

[P_Marlowe]

1) After a mayor suit opening, how many cards you need
for support depends a bit on partnership agreements,
more precise on the general structure of your mayor
suit raises.
But any 5-4 hand with a good 5 card suit, which is strong
enough to insist on game will do

After a minor suit opning strong jumb shifts wont occurr
very often, because you need 5 card support, and you
basically tell your partner, that you want to play the minor,
even if yu hold the mayor.

2) Taking Justins hand

KQJ9765
8
AT52
T

would be enough for me, you want to play spades, you are interested
in controlls and values in diamonds, tell your partner that you know
the trump suit.

3) 15-17 NT with a good 5 card suit

With kind regards
Marlowe

Don't want to spoil the party here but... why? One thing I agree on is that the jump bid should be well defined, so no vague "13+" or whatever, a small range. But why so strong? If you bothered to make this agreement you want it to actually come up. That makes a range like 13 - 15 (the idea is minimum GF, depends a bit on your opening style besides points are just a guideline anyway) much better.

Gerben, who never holds a strong ♣ opener in response to partner's 1-level opening bid.

That would make it come up more often, but you can deal with these hands easily anyway by making minimum forcing bids until you get to game. It's the hands with extra strength that are difficult to bid, so a balanced range of 15-17 or 16-18 seems more sensible to me.

... why?

Notice that I only mentioned the point range for balanced hands. So let's think about this, which balanced hands are toughest as responder? I don't know about you, but I rarely have a problem when I hold 13-15 pts in a balanced hand. However, when I hold a 17-count it is tough. I'm definitely interested in slam, but going past 3NT or 4M might not be safe.

So I think that 16-18 is a sensible range. I wrote 17-19 because I thought that's what Jilly wrote in her post. I notice now that she wrote 17-18, but I think that is a bit too restrictive, so I suggest 17-19 or 16-18. Just below a hand that's strong enough to force to slam.

At least there is one thing left that we agree about these days Gerben, it is good to have an agreement.

17-18 is Soloway, not me
