Well, the system does seem a lot better than the previous attempt. There are still a couple of glaring problems though. First of all, over 1C, you need an opening hand to bid something other than 1D (if not balanced)? Also, your 3C+ responses seem very unnecessary, 21+HCP is effectively a slam force (since this system is a weak nt, then opener either has extras or has shape), and when 2C can have 18-20, opener isn't going to jump the gun on you (and even if he did, you're not much worse off than if you bid 3C, at lease you know partner is not slam suitable!)
The 1D waiting bid also strikes me as being very vulnerable to competition, even something as simple as a 1S overcall is going to wreck havoc in your structure and could easily bury say your heart game completely. Say opener has some 1336 shape with a 14 count and the auction goes 1C-(P)-1D-(1S)-2C-(2S), responder is going to have a hard time getting a 5 card heart suit in (and maybe even 6, having to bid 3H on QJxxxx- eww).
Edit: Just saw the 1NT structure, is there any reason you require 7HCP to transfer O_o? I suspect most people would say that 16HCP isn't enough for a slam invite over a weak NT (traditionally you need 33 combined for slam, but you could get away with a bit less than 19, I'd say it would be at least a good 17 before you start searching)
(first edit removed on further inspection)
Yes, there have been significant improvements... Thanks for noticing.
There are a few simple reasons for allowing responder to bid something else other than some kind of waiting bid:
1. Responder should be captaining the auction, not competing in it, until opener has fully described his/her hand, unless, of course, responder has some rather significant hand and/or HCP.
2. With responder getting into the action, the partnership risks having the stronger hand become dummy - something generally not good.
3. With opener having a freer passage has the clear opportunity to describe his/her hand rather fully and accurately, especially when dealing with majors or NT.
4. Even with interference from opponents, responder does have additional tools, like a double, and others. I haven't delved into interference bidding yet, but, I can feel the tools being there.
5. Also, and finally, even with interference bidding, opener can still describe his/her hand with reasonable accuracy. For example, even if opener's RHO bids a major after opener's 1
♣ bid, opener can still bid 1N showing 15-18 HCP and a balanced hand, or 2 of the unbid major to show a 6-7 card suit, etc. the options are there, at least IMO.
As to requiring at least 7HCP for Stayman, that is simply an adjustment, upward, from the apparently normal requirement over a standard 1N opening bid.
Again, right now, the focus is on the majors, not so much the longer term sequences. The issues with those have to be recognized and resolved, which is why I was asking for help in this area: developing FDCCs...
