The dealer's main plan of a trump hand should be to exhaust trumps and bring in a suit.
Be cognisant of what you should accomplish and then decide how best to do it.
Pitfalls in the form of false leads, false cards and clever under-play should be dug for your adversaries at every opportunity.
Too much haste in showing ability to ruff in the weak trump hand frequently brings disaster.
When you are reasonably assured of every trick but one, lead your remaining trump.
