Opening Lead II — Suit Contracts
🎯 Learning Objective: To choose the right opening lead against a suit contract — where the priorities are different from no-trumps — and to understand when a singleton lead genuinely helps your side and when it only helps declarer.
💡 Key Idea: Against a suit contract, the opponents can ruff your long-suit winners, so patient length leads matter less than they do against no-trumps. What matters more is the safety of your lead, and whether an aggressive lead — a singleton, say — can actually be turned into extra tricks before declarer draws trumps and takes that chance away.
Ace from ace-king
Holding ace-king together, lead the ace. It lets you see dummy before deciding how to continue, and it is the house standard throughout these lessons. (Some partnerships prefer the king from this holding as an agreement — if you meet it, recognise it, but the ace is what you will play by default here.)
Top of a sequence
Exactly as against no-trumps: with three or more touching honours, lead the top one. This rule does not change between contract types.
The singleton lead — corrected logic
A singleton lead can produce a ruff for you later in the hand — but only if your side can actually reach that ruff before declarer draws trumps and removes the possibility. The lead itself is not the valuable part; the route back to it is. Before leading a singleton, ask: does my side have an entry to lead the suit again, or enough trump length or control that declarer cannot simply draw trumps and kill the ruff before I use it? A singleton led with no realistic way to reach a second round is just as likely to help declarer read the hand as it is to help you.
Example Deal 1 (4♠ by South)
♠ A K Q 4
♥ Q 8 3
♦ K 9 6 2
♣ 7 5
♠ 7 6 3
♥ A 7 2
♦ 5
♣ K Q J 10 9 8
♠ 9 5
♥ K J 10 6 5
♦ 8 7 4 3
♣ 6 2
♠ J 10 8 2
♥ 9 4
♦ A Q J 10
♣ A 4 3
This deal shows exactly why the singleton rule matters. West’s diamond singleton looks tempting — but count the trumps. Dummy and declarer hold eight spades between them; West holds three. When declarer draws trumps in three rounds, West must follow to every one of them and is left with no trumps at all. West’s heart ace is a re-entry to his own hand, not to a trump he no longer holds — so when he eventually gets in, there is nothing left to ruff the diamond with. The singleton lead has produced no ruff, and West has burned his best asset for nothing.
The right lead here is the club king from West’s rock-solid king-queen-jack-10-9-8. That establishes a genuine source of defensive tricks straight away, keeps the heart ace as a working entry to a suit the defence still has running, and does not depend on a ruff West cannot actually reach. The singleton looked like the exciting choice; the club sequence is the winning one. A singleton lead is only as good as your side’s route back to it — and this hand shows exactly what “route back” really means.
Leading from a doubleton
A doubleton lead — top of the two cards — is a milder version of the same idea: it can bring in a ruff on the second round, and it costs less than a singleton if it does not work out, since you still hold a card to follow with. It is a reasonable choice when a singleton is unavailable or unattractive and you want to keep the ruffing idea alive at lower risk.
Trump leads
Leading a trump is not an emergency measure — it is a legitimate, sometimes best, opening lead. It is particularly strong when you suspect declarer is planning to cross-ruff (score tricks by ruffing in both hands rather than drawing trumps), since a trump lead removes one of the trumps he needed for that plan before he can start. It is also reasonable with a trump holding that offers no useful lead elsewhere. This is covered in full in Leading a Trump later in this module.
Preferring a forcing defence
With four trumps yourself, be wary of a singleton lead purely for a ruff — you may do better leading your longest side suit repeatedly, forcing declarer to ruff in his own hand each time and wearing down his trump length until your own four trumps become more powerful than his remaining ones. This “forcing defence” is often a stronger long-term plan than a single ruff, particularly when declarer’s trump holding is not obviously long.
⚠️ What not to lead:
Don’t underlead an ace (lead low from a suit headed by the ace) as a default — this is a specific, named exception covered later, not an opening-lead habit.
Don’t lead a singleton “when in doubt.” Treat it as one option among several, chosen because the entry logic supports it — not the automatic fallback when nothing else looks clear.
Don’t lead away from a lone king or queen into a suit the opponents have bid strongly — this tends to hand declarer a cheap trick with no compensating chance for your side.
🧠 Memory Tip: A singleton needs a way back. Before you lead it, ask how your side reaches it a second time — an entry of your own, or enough trump control that declarer can’t clear it away first.
Summary
Against suit contracts, lead the ace from ace-king, and the top of a genuine sequence exactly as against no-trumps. A singleton lead is only as good as your side’s route back to it — an entry, or trump control that survives declarer’s attempt to draw trumps — so treat it as a deliberate choice, not a default. A doubleton lead offers the same idea at lower risk. Trump leads are a legitimate first choice, especially against a suspected cross-ruff, and with four trumps yourself a forcing defence can outperform a single ruff. Never underlead an ace as a habit, and never lead a singleton simply because nothing else looks clear.
