Jack Denies

A lead agreement that the lead of the Jack denies a higher honor card, the lead of the 10 or 9 implies 0 or 2 higher honor cards.  Playing Jack Denies leads you lead the red card from the following:

AJT...        AT9...

KJT...        KT9...       KQJ...

QJT...       QT9...

JT....         T9...

These leads can be very descriptive, for example:

              Lead:   J

                             Dummy:   A3

             You:     Q52

When dummy wins the ace you know who has the King.  Playing standard leads you would still be in doubt.

Unfortunately they might also tell declarer too much:

                        Dummy:   AQ32

        Lead:  T

                            You:    J

In this case you know who has the King, RHO.
