Up to now partner and I have agreed that we take out to 3♣ via 2♠ showing either 11 HCP or a 7+ minor. Partner bids 2NT with 12 HCP and 3♣ with 14 HCP. With 13 HCP he upgrades or downgrades. The alternative is to bid Stayman followed by 3♣/3♦, but partner has another partner who likes the response 2♠ = 11 HCP and 2NT = 12 HCP and this seemed like a reasonable compromise.
Others have answered your question(s), but I just wanted to comment on the above method.
In UK it is quite popular among the lower echelon players to use 2S to show 11 HCP and 2N to show 12. This is seriously bad. It is true that if you are going to do that, you might as well make the best of a bad job by including some more hand types in the 2S response, such as a weak long minor (incidentally, with the right hand a 6 card minor is sufficient, no need to insist on 7). You could also include a quantitative 4N hand type in 2S to make more mileage out of it.
The method evolved out of a spare unused bid and whoever addressed the matter was so challenged in imagination that this was the best that they could come up with, as well as lacking the imagination to research other bespoke response structures that had already been invented. Presumably they considered minimising the impact on other responses as being a higher priority than building a half decent system.
May I ask the advocates of this method one question: What do you regard as a higher priority, between investigating a 4-4 major suit fit or distinguishing between 11 and 12 HCP? If you have a 4 card major and choose to look for a fit via Stayman, how do you then distinguish between 11 and 12 when partner does not have your 4 card major? If you choose to show your points via 2S/2N, do you agree that you risk losing a major fit?
There are certainly some partnerships who will tend to deny a major when bidding 2S/2N (4333 shape possibly an exception), and effectively give up on distinguishing between 11 v 12 on hands that are worth looking for a major. In so doing they tacitly admit that the distinction between 11 and 12 cannot be THAT important. Incidentally they seldom seem to disclose that part of the agreement.
