it requires lho to have opened a systemic 2 card club and rho to have raised to a systemic 2c on his 5 card support. as for how to cater for partner's various hand types, that's the tricky part, hence my desire to keep the bidding as low as possible.
I understand the desire to keep the bidding low.
However, when one makes a responsive double of 2
♣, one doesn't promise a rebid. Indeed, in these auctions, it would be common for advancer to hold something like a 4=4=3=2/4=4=2=3 8 count or so.
That means that doubler will strain to bid his cheapest 4 card major, rather than his cheapest 4 card suit.
In turn that means that advancer can't distinguish a 2
♥ call by doubler as being, say, your dreaded 4=4=2=3 or my more common 4=4=4=1.
In addition, while it may be convenient, when answering this problem, to assert that double followed by 3
♦ is forcing, I would be very surprised if that view were remotely close to being universally understood in that way. I am not saying that there is no argument for saying it should be forcing, and not even saying that I wouldn't decide at the table that it was forcing. It is to say that after playing bridge for more than 40 years, including at various world championships and in several partnerships with beyond the average amounts of agreements, I have never discussed this auction of double then 3
♦ with anyone.
Bitter experience has proven that just because I think an auction should have one meaning doesn't mean that another very strong expert has a different idea.
So I do think that you have created a problem for yourself, in your legitimate effort to get by this round. That is why I bid 3
♣. Unlike the double, this promises another bid, so advancer will bid up the line, and not the cheaper major. I am not going to survive 4=4=2=3 very often, but then neither are you, and meanwhile, on the far more common layouts, I will reach game, and maybe even slam, more comfortably and probably more frequently, when right, than you are.
Note that this is far different from 1M x 2M x, where doubler should assume that the double is about the minors, on the reasonable basis that advancer will always bid the other major with length there. When their suit is a minor, double is usually about the majors.
