Just change the resposnes to stayman, I have seen people play 2 range and 3 range (2 level with min, 2N with max is 2 levels, 2 level with min 2N with medium 3 level with max is 3 ranges). You can add a lot more depending on if they open a minor or a major, for instance if they open 1H then I think you should play 2D and 2S are min, 2H is medium with 4 spades (so you can still stop in 2S after garbage stayman if partner has 4S and 5D less than invite for instance), 2N with max.
Over the majors, this messes up your garbage stayman somewhat but that hand type is not that common anyways and playing 3D or 3S might not be a disaster. Over the minors I don't play 3 range because I don't play 11-16 (for instance I think over a 1C opener and a balancing 1N, 11-14 is a totally fine range because you will often be able to get to X and bid 1N with 15-17 or w/e, obviously over 1S if you X you commit your side to 2N hence the very wide range for the balancing 1N over majors).
Ok, I'm going to admit it. I have never understood the concept of range stayman and the 2n response.
If it goes 2c-2n showing a max, responder will never pass (after all, he was going to at least invite opposite a minimum). There's no room to reinvite, so you're forced to game. Which means that you would have accomplished precisely the same thing by bidding 2d (or 2M) and accepting any invite. If responder was thinking about inviting slam opposite a max, then yes, this helps, but a hand that passed over the opening bid will probably be inviting slam approximately never.
Now, if you can show a max with 4 in the other major at 2M then that does help, because now responder can invite opposite the max. Also you get to play 2 instead of 3 when 1N bidder has a min and responder has an invite. So that's a very neat idea, thanks. But I still don't understand the point of the 2N response.
Edit: Ok, playing 2c-2n showing a max, you might choose to stop in 2M opposite a min. But that's the only gain I see.
Am I missing something?
