Strange that I never saw this, but a somewhat interesting parallel seemed to arise today.
On BBF, a problem auction was provided where Opener has 5332 and Responder a balanced monster, the partnerships of many ending in 6S down immediately on a club lead (missing Ace and King). The short form of the story, IMO, was that Jacoby 2NT was flawed and thus ill-advised, whereas simple cues worked better (obviously).
The deeper story was the auction many of us will now use to get to thsat cuebidding spot:
O: One Spade
R: Two Clubs (real clubs OR just spade support)
O: Two Diamonds (real diamonds OR just balanced with a diamond card)
R: Two Spades (fit, start cuebidding...)
A "strong clubber" made a comment about how this type of bidding is why strong clubbers are better. As a sometimes strong clubber myself, I found this absurdly humorous, as Opener starts 1S either way and as my methods in a Precision-style strong club would mean the exact same start.
Furthermore, and the point of this post, I noticed that there would be a strong parallel using canape, albeit slightly different:
O: 1D (if diamonds and a major, diamonds could be 3-card if 5332)
R: 2C (GF, artificial)
O: 2H (diamonds plus spades; diamonds might be 3-card)
R: 2S (fit, start cuebidding...)
Strangely, then, a parallel arose. On the same hands where with 2/1 GF (or Precision for that matter) I would rebid 2D after opening a major and hearing 2C, I would open 1D canape and then show the major. This of course seems right -- canape means essentially getting to the second bid first. Sending in the reserves and holding back the main army until later. But, the decision-making is the same.
This is an example illustrating why I think learning multiple systems, and playing them enough to be competent in each, actually helps thinking in all systems. In other words, Precision helps your 2/1 game, and 2/1 helps canape, and K-S helps Standard American.
