Any trump opening from your partner is an indication of strength,
usually of strength in the side suits. It does not necessarily
follow that your partner wants the trumps out, but _it is_ an
indication that he is anxious to have his suits led to. If you win
the first trick in the trump suit, look to see if dummy offers you
an advantageous lead. If you hold fair strength in the side suits
with no protected honour in trumps and no short suit, there can be no
objection to the return of the trump lead; but if you hold a tenace
over dummy’s strength in trumps, or a high card that is protected,
it would be a bad play to return the trump lead. Wait until your
partner or the adversary leads up to you. Do not return the trump
lead if you hold a short suit. Lead the short suit. You may be given
an opportunity to make one of your trumps.
