Thank you all for the replies! Diana_Eva, I want it to test it with other bidding systems software and to play, of course. Bubalu1997, I know I can use what you propose, but this is good only for NT. Where my system is really good (or so I think as my brainchild :) ) is opening one in the majors. Matmat, if I could write it, I would not ask for it. Anyway, this seems to remain a wishful thinking on my part. Once again, thank you to all and great moments at the bridge table!
