I like it. But a responding GF hand with a 6cd minor and one or two 3cd majors is a constant irritant. It seems the choices are equally poor: Bid as a long minor and risk losing a 4M game, or puppet and try to figure out where responder's stiff might be. 5m-4M-3-1 hands are not a problem.
Are there reasonable solutions?
