Interesting. I should have defined our 3♠ response, which is not the same, sorry.
But I don't want to spoil things for those opening 1♣.
Let's suspend the 2NT variant for now and concentrate on what the 1♦ response promises (for me it could be weak with clubs, as well as unlimited diamonds) and how one rebids over that.
How one chooses to open should be influenced by the methods one has available after your various options.
Adam’s point about style is important. Were I to open 1C, then we play transfers and, unless we have club length (as responder) it is very rare that we pass. Our CC says that a response should usually show 3+ hcp, but we’ve responded on 2 in the past. So I’m not afraid of missing game but I choose to show a strong balanced hand because of slam potential. It helps that we have a complex and, I think, pretty good 2N structure, whether after 2C 2D 2N or 2N.
For us 3S forces 3N. It’s unsafe to reject since 3S is not only for some minor slam tries but, more commonly, the only way to reach 3N. 2N 3N is a mild minor slam try, often 54/45 minors with around 10 hcp. We’ve found this to be surprisingly powerful. As responder, with only 54/45 minor shape and roughly 10 hcp it’s dangerous to look for a minor fit absent this agreement since 3N rates to be the best contract most of the time, yet slam can be great opposite major suit controls and a fit. The cost is obvious…having to bid 3S in order to reach 3N will someday allow for an effective lead directing double. It’s bound to happen but it hasn’t so far and I’d estimate we have picked up eight or nine slam swings since we adopted the method.
If we were to bid 1C then partner will bid 1S with most hands that lack a major. That’s a very bad sequence for us…the 1S response makes showing this hand almost impossible. Every method has hands it can’t handle and, for us, this would be one after 1C 1S. I’d force to game but at the cost of distorting my hand (I’d reverse, usually promising 5+ clubs as well as showing a 4 card heart suit and then bid 3N over any ingberman bid).
