HOW TO PLAY TO PARTNER’S TRUMP OPENING
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.
