Pairs at the local club, MPs, 3S raise is natural (i.e. no difference after interference). The system we play is 4 card, 12+hcps openings (Nordic standard). Opps are vulnerable. I am sitting east.
5S went one down. P said that I can not bid 4S holding all those hcps in hearts. I think the jack of hearts is the only bad hcp I have and I think that 4H could possibly be passed out and even doubled might not be a good score. And from what I have gathered so far, the hand that bids the invitational hand should then not bid 5S and let the opener decide.
Questions:
1. Is the 4S an overbid (singleton and an extra trump as we play 4 card majors, and obvious shortness from P in hearts are plus points, 5 hcps in opps suit is the negative point)?
2. Is the 5S bid usual/allowed?
