According to your list they also have no opening for hands with both minors and 4441s. It seems quite likely to me that you have an incomplete understanding of their system from the few hands you played against them and they either use 2♦ and/or 2NT to cover some of these hands or bundle them into a lower opening such as 1♣.
Turns out you were right about this. Having now played many more hands against these guys, I still think it is a dumb system. The opening bid is based on where the MAJORITY of HCP's lie, minimum suit length = 3. The better players in the club are starting to exploit this weakness in their system. It tells you in which direction to take any needed finesse in all 4 suits! To update the first post on this crazy agreement, this is what we now have -
1
♣ = majority of HCP's are in the black suits
1
♦ = majority of HCP's are in the red suits
1
♥ = majority of HCP's are in
♥ and
♣
1
♠ = majority of HCP's are in
♠ and
♦
1NT = majority of HCP's are in the majors
2
♣ = 1 suited hand, 16+ HCP's
2
♦ = 1 suited hand, 16+ HCP's
2
♥ = 1 suited hand, 16+ HCP's
2
♠ = 1 suited hand, 16+ HCP's
The only thing about this crazy agreement which (to me) seems to have any merit is this: the more cards you have in the two suits shown with the opening bid, the lower the HCP count needed for the opening bid.
Just to illustrate this dumb agreement, last night these guys missed a laydown 4
♥ contract. The opener had 5 babies without a single honour. He had (I think) 12 HCP's in total with the majority concentrated in
♠ and
♦. Systemically he opened 1
♠, his partner had preference for
♦ and they ended up playing in 2
♦ which made. Responder had 3 cards in the
♥ suit, all of them honours. Everyone else bid and made 4
♥.
