Does anyone play that 1 of a minor followed by 2 of a major by partner shows 10+ points and 5+ in the major?

Partner and I have been trying this and it seems to work GREAT
except when there is interfernce.

We are unsure how to handle interference.

Can someone help??

Thank you

You mean a jump shift? Like
1♦-(pass)-2♠?

No, this takes away a lot of bidding space so it has to be very precise. If it is 10+, presumably 2NT, 3♦ and 3♠ would all be nonforcing so with 14 points, opener would have to jump rebid or reverse. What about a 3♣ rebid? There are hands that would like to make a nonforcing 3♣ bid and other that would like to make a forcing 3♣ bid.

5+ is also too vague. We have a lot to sort out: spade fit or not, fit in some other suit, stoppers for notrump, general strength and controls for slam.

Most 10+ hands with 5+ spades can just start with 1♠.

Play the 2♠ bid as game forcing with a one-suited hand or 5 spades with a diamond fit. Balanced hands and hands with interest in a hearts or clubs contract should always start with 1♠.

Alternatively, play 2♠ as nonforcing with six spades, say 0-5 or 4-8 or 9-11 or whatever range you prefer. Whatever meaning you decide, it has to be very specific so opener can make an informed decision.

10+ and 5+ sounds like a 1S response. I prefer the jump shifts to be fit jumps (good spades with a diamond fit, GF) or weak (6+, 4-7 HCPs). The latter offers an advantage that after 1x-1M; 2y you can play 2M rebid as more constructive (8-11) and 3M as GF, avoiding the need for an awkward jump to 3M on invitational hands.

10+ isn't GF so might have to stop short of game.
10+ is unlimited so must be forcing.
So some of your possible contracts are 3M, 3N and 4M.

So, you have used up all out of space and no closer to knowing what the final contract is. Worse the right contract could be 3S, so might only have one more bid.

A jump to be useful needs at least to be GF or limited.

I agree that it needs a better definition.

I play it as game forcing, strong but with a suit that will play opposite a stiff petunia. AKJTxxx and a mere opening bid is fine. Since it could be much better cue bids happen immediately if indicated and although rare it's been a big plus every time it happens.

After a (semi-) balanced 1♣ I play 2M as 6 card up to 8 hcp, and while not rare, it has been a big plus every time it happens. Interference has no impact.
Choose something that fits the rest of the system. All bids should fit together in a coherent whole with no hole.
Hence another sequence means 6 card 9-12.

I agree.
When (occasionally) I play a good old fashioned natural with the club president, 2♠ is game forcing with a well honoured one-suited hand.
The rest of the time it is nonforcing with six spades, 0-6.
But some fit-showing meaning would be equally valid, the important thing is to be specific and let the other bids work.

helene_t response makes a lot of good points.

It may be old fashioned, but these strong hands can be surprisingly difficult to handle if you start with 1♠ as it can be difficulyt to create a forcing auction.

We play 0-4 - we would respond 1♠ with a six-card suit and 5 HCP (and sometimes with 4 HCP).

A range of (say) 5-8 can also be useful. This allows a sequence such as 1♦, 1♠; 2♣; 2♠ to be a constructive bid. I haven't come across Helene's final suggestion (9-11), but presumably this reverses the constructive / non-constructive sequences.

XYZ solves that difficulty nicely.
What I like about the old fashioned 2♠ is the possibility to depict solid or semi-solid ♠ as well as strength, makes things easy for partner.
