1♣ openings - basic
These may be played to have any meaning, forcing or not, as long as this does not include unbalanced hands with 5+ Hearts or 5+ Spades (unless there is a minor suit of equal length or longer).
I believe I looked at the EBU licensing agreements when I designed it and it came up as permitted, which is why I was surprised that it qualifies as a HUM by WBF standards.
I thought the purpose of WBF standards was to cover most bidding systems that are popular around the world, which is why Polish Club systems are permitted because they are popular in Poland. If MAF is very popular in the Netherlands then it should similarly come up as an exception.
Is there, by the way, a way of requesting to a WBF committee that a method should be categorised as not being HUM?
As for jdonn, I said the system is "natural" because generally it is, i.e. you bid when you have a normal-range opening hand and you open 1 of a major when you have 5 of them and 1NT with a balanced hand. So many systems have different "non-natural" meanings to 1
♣ and 1
♦ openings that I would not have considered my own variation any more non-natural than those.
Yes, the method is fairly unusual because it is not generally taught to beginners or intermediate learners, but why should that mean it is forbidden to play?
I don't know why you consider the system comes with a minimum of improvement and maximum of confusion. What is so confusing about 1
♣ showing a 4-card major and 1
♦ denying?
As for the benefit, it is obvious when you think of it that you find most major-suit fits. If the opening bid is 1
♣, responder has a chance if allowed to respond 1
♦ which shows a 4-card major somewhere and you can then find out if it's the same one. If responder has a 5-card major they bid it immediately and opener knows it is a 5-card suit and has no problems raising with 3. Over a 1
♦ opening it is rare that responder would bother to show a 4-card major.
Yes, it is true you can't find every major fit. When the opening bid is 1NT (16-18 in the system the way I play it, 15-17 in MAF) and responder doesn't have the values to go to 2NT obviously you may miss a 4-4 major if responder passes. It is also not totally clear how the fit is always found after an opening major bid, particularly 1
♥ where responder might have 4 or 5 spades for a 1
♠ response.
I know that standard systems have nmf/checkback etc to find fits but finding out at the 1-level that the 1
♠ response promises 5 can be very useful in continuing the auction, both with and without intervention.
The system is much simpler than MAF in that it doesn't go into a sequence of relays and transfers, although there is a generic pattern than a 2
♣ response is artificial with game-invite values and 2
♦ with game-forcing values (both of these are definitely permitted).
