I'm sorry if the question was unclear. I meant to ask what the minimum for the three different opening bid was. In this case opener had ♠AKQxxxxx, singleton ♥, void ♦ and four ♣. It seems to me that opening 4♠ is about right: a good pre-empt, 8 playing tricks, in second position. Opening 1♠ is not good I think. I saw that some responders raised to 6♠ and frankly I don't see why. Next time I'm going to pass again. Have to admit I prefer a more solid style these days :)
