I love coming up with new meanings for opening 2D. A sick hobby, perhaps. Well, here's another, inspired by my thinking again on "delayed canapes."
There are two 5431's where delayed canape does not help:
Interesting. This suggests that a 2D opening could show these. 14-17 or so HCP, with 1345 or 1435.
But, then you could add in 1-4-4-4 fairly safely.
You now have a three-suited opening, flexible like the Precision three-suited 2D opening (not strictly 4-4-4-1), with like Precision a known shortness (here, spades). 2D as 1345/1435/1444, 14-17 HCP or so.
Unlike the Precision 2D (3415/4315/4414/4405), it is easier to pass this 2D call. Plus, the available asking bid of 2S (retaining the meaning of 2NT as natural) is much less painful.
2NT = 1345
3C = 1435
3D = 1444
3S after answer as slam probe?
Something like that. This could be coupled with 2H as H+C and 2S as S+minor to solve all high-reverse problems. Perhaps r-on-w or 4th seat?
