No convention is perfect, and I happen to like rubensohl, Frances
Anyway, I would choose the ambiguous 2N, and hope that I can bid 4
♥ next, to show a gf with (probably) 4=6...with 4=5, i would probably be more inclined to bid 3
♥ if that were available to me (which, in my methods, it would not be... I'd be interested in knowing the full structure.. maybe I'll like it better than I do Rubensohl).
I would choose this approach over a direct 3
♥ because this hand has slam potential... and partner may be able to visualize this if I pattern out... xx AQxx Axx Axxx is not a 1N opening, but 6
♥ is a fair contract.
If LHO spoils my plans via 4
♠, I bid 4N... long clubs, gf, short spades, second suit somewhere.... if partner has, for example, xx AQxx AQxx Axx, he can bid 6
♦ pass or correct (I am allowed to dream, am I not?)
