Strategy: Why "Short Suits" are Your Best Friend in Spades
Creating a Void
If you have a "singleton" (only one card of a suit), lead it immediately. Once that card is gone, you are "void" in that suit. The next time that suit is led, you can cut and take control of the table.
Setting Up Your Partner
If you know your partner is short in a suit, lead that suit to let them cut. This is a primary tactic for setting opponents who think their Aces are safe.
