Diana, you'll have to post the whole sequence and hands as post-mortem now!
Hi Diana_eva
Good topic.
First of all,I am very sorry,without your prior consent,I released this hand.I think error is not a simple thing,even not caused by one person.
1- I know both of opener and responder are temporary partners,not regular.
2- There are some issues in standard Jacoby 2nt.
In according to the approach of Audrey Grant (www.AudreyGrant.com),if you directly bid up to 4
♥,showing minmum hand without singleton or void.
With this hand,you should rebid 3
♣ ,showing singleton or void in clubs because this is likely to be the most useful feature in this hand to help responder decide whether to pursue a slam.
However with this hand,a great pity that the responder can't recognize his hand after 3
♣. As we know it is very important to reevaluate after 3
♣ showing S/V.In the face of S/V in
♣, responder's
♣K in
♣ suit is wasted point,now actually there are only 11 working points in responder's hand,obviously it is a decreased values.so responder would better jump bid to 4
♥,or if play non-serious 3nt,responder can rebid 3nt after 3
♠,let opener describe own hand again, this is the last life-saving straw.I am afraid responder think opener might have some extra values especially after cuebid 3
♠.
When with this opener's minmum hand with a Ace and a singleton in some side suit,how to handle?
After Jacoby 2nt, opener bid up to game without S/V in the minmum hand while responder have extra values,now how to do next?
It is very difficult to handle by traditional standard Jacoby 2nt. Traditional standard Jacoby 2nt is very rough actually.
World famous USA expert of two over one bidding system,Max Hardy and his partner Jimmy Jacoby,they thought all of disasters of Jacoby 2nt are caused by responder without extra values to be wrongly as a captain ,when no extra values with 12-14hcp ,responder can't afford the unsuccessful failure of imaginative slam.
So Jimmy Jacoby had revised anew Jacoby 2nt before dying,in which it ask responder have to 15+hcp at least with 4-card support.
