Hi all. I don't know if I will be able of to explain in my bad English what I think however the opening bid 2
♦, but thats it is a typical opening bid used in Italy and in the time the players they have developed many systems to interfere and to defend.
The first thing to be remembered is that here in Italy the opening 2
♦ are allowed with different types of hands:
weak with major (
♥ or
♠), strong with long suit minor (
♣ or
♦), balanced strong or strong three suiter.
After the opening 2
♦ the second player has various interferences:
dbl = interest for the
♥
pass then dbl to the second bid = interest for the
♠
3
♣/
♦ = natural with the
♣/
♦
4
♣ = 5/5 minor normal
4
♦ = 5/5 minor forcing manche
This is the system that I play and how thin to today he is be effective.
Since the opening bid 2
♦ can also hide strong hands with a balanced hand, 11-12 points and no 4 card suit in major it is preferable to pass and to attend the following bid of the opponents, with strong balanced hand too, you can dbl or bid NT in the 2nd bid.
For this reason to the place of West (if i play with my usually partner), knowing that the dbl of my pard cannot have interest for the
♠, I would have bid 3
♥ (sign off) or 2NT (you have put the distributions but not the points).
IMHO
