A Madala
6. It seems that my partner has a hand like: 6-4-3-0 or 5-5-3-0 or 5-4-4-0, if not he would have said 4Â over the 4-Pass-Pass. The Pass is certainly forcing, so with 0 points in hearts, and a seven cards suit with a TOP honor and a singleton, I can not do anything different to report it. He can bid 7 or say 6.
M. Bessis
6. I hope a void after partner’s Pass, but would rather have bid 5 in my first turn.
T. Bessis
6! My partner partner has shown enough to double 4, but has not doubled the 5th level, so there are many chances that he is void in hearts.
 V. Giubilo
As the quiz has been proposed I say 5, but I do not feel happy to do so, after having said 4. I would rather say 5, after bidding 5 in the first round of the auction.
R. Cerreto
6. The Pass over 5 is forcing (for me). My partner showed strengt6h and I have a seven cards suit that I didnt show yet.
P. Clair
5. Honestly I do not know exactly what to do !! So I do not risk to interpret the Pass of my partner. If he has club complement, we will able to make 5 (and N/S hearts), if he has his values in his diamonds we will be down. I’m not going to act shy – stating Pass – therefore I throw 5 – knowing that I’m risking – for two reasons: these doubles at this high levels are to lose or to win, especially because I dont have the courage to attack with my singleton diamond (when there could be two spades and a club trick… ).
M. Moristch
Pass, because I fear 5Â and I think we can defeat 5, with a possible diamond ruff.
