The evolution is underway as we look at this screen. SAYC gives way to 2/1, high card point count gives way to the Law of Total Tricks, most of strong two level openings gave way to the preemptive ones.
Of course, what comes next is better. And simpler!
The artificial game-forcing two club opening is not nearly as effective as an artificial one club semi-game-forcing opening (Precision style). Once the partner approves of game-going aspirations (8 or more high card points), the information exchange starts at one level! Additionally, the precision of bidding after natural 11-15 high card point openings increases tremendously. The key is that the vast majority of your existing bidding agreements does not change.
With all the buzz about the Law of Total Tricks, we often do not realize that the Law stems from a simpler basic principle that applies to both one-sided and competitive auctions. Now we can calculate the number of tricks from the combined high card point count and the presence of extra trumps alone. If the opponents bid, we do the calculation for them and have a straightforward answer whether to compete, pass or double.
Finally, with the Multi two diamond reigning in Europe, why not play a light version that is acceptable under the General Convention Chart? Yes, we have an unspecified major (4 or 5 cards), but also have 5 or more diamonds to make this two diamond opening natural. The opening occurs roughly once a session! While it is a preemptive one, it allows precise game and slam bidding.
