I think the argument against forcing pass being allowed is more an argument against the fert than anything else.
Basically the point is that my partnership will need a defense to an opening of X which shows Y... for any choice of X and Y. Simply enumerating all the options is going to be impossible even under pretty stringent system restrictions, so I'm going to have to categorize these calls somehow. If everyone is playing methods which fall into a small number of categories, this is going to be a lot less work than if "anything goes."
Hi Adam
I think that you have this one backwards.
In my experience, there isn't much difference between ferts.
Almost all weak opening systems have one fert.
This fert (essentially) shows a weak hand with 0-7 or 0-8 HCPs.
The edges may be a bit ragged. Potentially, you open a week bit lighter with a 4 card major or a wee bit stronger with a balanced hand.
But you don't have one fert for hands with four card major and another for hands without one.
The variance in the ferts shows up in what suit shows the bad hand.
Ranges between 1
♦ and 1
♠ seem most popular, though Marston - Burgess used a 2
♣ fert NV.
Conversely, I see an amazing variance in the structure of the opening bids used in weak opening systems.
Some pairs prefer transfers
Others prefer wonder bids
Others clarify shape (1
♠ shows a 5-5 pattern, but says nothing about suits)
This is where life gets really complicated.
You have a plethora of these different opening bids and they are often very artificial.
Regardless of what people says about ferts or destructive bidding or whatever, what they really object to is the fact that partnership that has studied their own set of openings is going to be better positioned when these occur that some random pair off the street.
