An occasional partner suggested I drop (very) weak-jump-shifts, and instead play 1m-2M as a 6-card suit with around 6-8 HCP. The sort of hand that would usually respond 1M and then repeat the suit at the 2-level over pretty much any rebid from opener.

What do folk think of this treatment? If you think it's silly, what is the best use for the jump-shift?

And if you like it / use it, what do you do with the now available sequence :
1m - 1M
(any)- 2M

Thanks,

I prefer strong jump shifts. I don't mind playing 6-8 and a 6 card suit and have done so before. I dislike very weak jump shifts as I find they tend to pre empt partner.

1m - 1M
(any)- 2M
I would play this as 10-11 unless you play a nice Polish gadget here.

I prefer reverse flannery (discussed other places in this forum). It shows 5+ spades and 4+ hearts and either constructive or limit raise values (2H is 6-9 2S is 10-12).

I also play reverse flan and like it. I think natural and invitational is a good treatment too.

I like it and play it, in most sequences. Whatever you do it has to fit in with the system and define things that can't be bid in other ways.

With one partner I play a simple natural response to a heart open of 1♠, where this is 4+ and unlimited:
1♥ 1♠ 1NT/2apples 2♠ = an invitational 11/12 with 6 spades, can be passed
1♥ 2♠ is a weak 2 = 6 card 5-9 and probably a heart singleton/void.
However, with another partner, 1♥ 2♠ is a 4 card support GF, giving more room in the followups. With that partner I play Kaplan inversion where 1♥ 1♠ may be (normally) a 4 card suit (or fewer) and 1♥ 1NT is unlimited 5+ spades. Then we use:
1♥ 1♠ 1NT/2apples 2♠ = 6 card suit 6-10
1♥ 1NT 2apples 2♠ = 6 card suit 11/12

With playing with regular partners that play transfer walsh we have the sequences:
1♣ 1♦/♥(showing the major above) 1♥/♠ (the major, denying 4 card support) 2♥/♠ = 6 card 9-12
1♣ 2♥/♠ = 6 card 5-8
This works very well, and I am delighted with it. This is made effective because the 1♣ open guarantees at least a doubleton in each major, and thus an assured fit, because ...

We play a diamond open that will have 6 diamonds or have a shortage. Playing the weak jump response with that is a little foolish, as that is likely to be opener's void/singleton. We play 1♦ 2♥/♠ as an invitational 6 card suit that is safe to convert to 2NT.

Thoroughly recommended if it complements the rest of the system.

I play 1D - 2S as very weak (to 7) and 1D - 1S - 1N/2m - 2S as about 8-9. This fits in well with my system (stronger hands would have started 1H) but is probably not as good for a purely natural system as the reverse Flannery and invitational suggestions already given. I also played these bids as fit jumps in one partnership.

i vote for reverse flannery by responder for 1m-2H. You can use 1m-2S as weak long suit, or you can divide your reverse flannery hands into two ranges, one for 1m-2H and the higher one for 1m-2S. i play both ways, depending upon partner's preference.
