Do you have any book references for this? I've never seen this recommended other than by you. J shows the ten and denies a higher *touching* honor, the Q, but I've never seen anyone say that it denies a *non-touching* honor. I have Kantar & Root books recommending encouraging signals J from KJT9 and T from QT98.
What's the advantage of showing partner the JT here, with declarer having the KQ? Why not just discourage not holding the K for the same effect?
Hi Stephen,
There is no consensus on what the J shows. Here is a recent Debbie Rosenberg question in Bridgewinners showing the point:
JACK. So an agreement is necessary. I use Kantar's Advanced Defense books too as reference, but am unsure they mention the specific situation.
Signalling the J when declarer holds the KQ would appear to me to be suit preference not top of sequence. (Signals are context dependent). But that's not what the OP wanted to talk about.
Here with Qx in dummy, Signalling with the J can be ambiguous (does it promise the K or deny the K)?
I like denying the king for 2 reasons: 1) I often open J109xx suits and don't want partner to confuse the opening bid with an attitude signal.
2) I have other good positive attitude cards without having to play the J.
High cards are encouraging, but at some point an honor shows soemthing else. Some make the division the Q so the J is a high card (see Phil's comment) and some make it the J so the 10 is a high card.
After a dummy with Kx and I am holding AQJTxx, it would never cross my mind to play the Q as an encouraging signal.
Getting back to the NC forum OP, If you agree J is a high card and does not deny a higher honor, then the J will work. So, likely will the 10.
your lower(est) cards are discouraging.
Finally let me add that a holding like J10987 can test any partner because playing standard signals partner has to understand by reading the other spots available that the 7 is a low card and you do not want a continuation.
