Good defenders do not just follow suit: they count. The single most useful count is how many tricks declarer can take right now. That number answers the key strategic question on defense:
- Declarer has enough tricks to make? Defend actively: cash winners, attack new suits, take risks.
- Declarer is short of tricks? Defend passively: exit safely, give nothing away, and let the contract die on its own.
How to Count at Trick One
When dummy comes down, add up declarer's sure tricks the same way declarer does:
- Count top winners in each suit (aces, protected kings and queens in sequence).
- Count the tricks a long suit will produce once it is established. Dummy's KQJ109 opposite small cards is four tricks as soon as the ace is knocked out.
- Use the auction: a 1NT opener holds 15-17, so once you see dummy and your own hand you can often place most missing honors.
East plays 3NT after opening 1NT. You are South; West is dummy. Count declarer's tricks before playing to trick two.
You lead the ♣J (top of an interior sequence) against 3NT. Declarer wins and knocks out partner's ♦A. Now count declarer's tricks: four diamonds in dummy once the ace is gone, at least two spades, and the club trick already taken makes seven, with the hearts still to come. Declarer opened 1NT, so the missing spade and heart honors are all on your right.
The count says nine tricks are ready the moment declarer regains the lead. Passive defense is dead: partner must shift to a club immediately when in with the ♦A, setting up your ♣109 while you still hold the ♥A as an entry. Count first, then defend: without the count, a "safe" heart or spade return hands declarer the contract.
TipMake the count a habit: every time dummy appears, pause and count declarer's sure tricks before playing to trick one. Ten seconds of counting prevents most defensive errors.
Active or Passive: the Decision Table
| Declarer's tricks | Your plan | Typical plays |
|---|---|---|
| Enough to make | Active | Cash aces, lead from tenaces, try for ruffs |
| One or two short | Balanced | Set up your longest suit, keep entries |
| Far from enough | Passive | Safe exits, no new suits, make declarer work |
The most common defensive error at club level is breaking a new suit when declarer was always going down. The count is what tells you to sit back.
Against 3NT, dummy hits with KQJ109 of diamonds and no side entry. Declarer knocks out your partner's diamond ace at trick two. You count nine tricks ready for declarer. What should the defense do?
