LEADING TRUMPS
One of the worst faults of the beginner is refusing to lead trumps. When you hold seven or more trumps in the two hands, usually lead them. If you hold commanding suit cards, the trump lead will prevent their being ruffed. When you have no suit to make the lead will establish your trump suit. If you hold high cards that should be led up to, lead trumps to throw the lead and to compel the adversaries to lead to you.
Arrange to lead your trumps advantageously—from the weak hand to the strong.
After trumps are exhausted, try to clearer establish the longest suit in the two hands.
It is usually good play to draw two trumps for one; but when the best trump is against you, do not waste two of yours to get it out.
Lead the losing trump only when you have an established suit and a sure re-entry.
When you hold one or more trumps and a losing card, always lead the trumps. This will force the adversaries to discard and they may not save the right suit.
Aim to discard your losing cards from the one hand, on the commanding cards in the other.
With a weak hand you are more likely to make your high cards if you put your adversaries in the lead.
