| Count | What it tells you |
|---|---|
| Shape | Declarer's cards suit by suit โ you know 26 from trick one; each card played forces the rest |
| Tricks | How many he can make โ this count alone decides whether you attack or defend |
| Points | Your HCP + dummy's + what he's shown = what partner must hold |
| Principle | Detail |
|---|---|
| Whoever knows more steers | Not about skill โ about who, right now, has counted more of the hand |
| Prevent, don't diagnose | If partner would face a guess, take it away โ lead the suit yourself, or discard the card that removes the guess |
| Overtake to protect | Keep the lead in the hand with the fuller picture, even at the cost of partner's honour scoring |
| Message before the crisis | A vigorous suit-preference signal, played early, steers partner through a squeeze he can't yet see |
| Play | When |
|---|---|
| Low โ the default | Second to a led suit: rising spends your honour at declarer's chosen moment and shows where it sits |
| Win cheaply | Bare ace over a lead you can't otherwise beat โ no patience to reward, take it |
| Clock against you | If ducking lets declarer establish winners first, rise and take your trick while it's yours |
| Trump / ruff at stake | Rise to protect a trump trick or to stop declarer ruffing a loser |
| Split equal honours | K-Q over a lead โ playing one can beat a finesse a plain low card would let succeed |
| Layer | Detail |
|---|---|
| Default | Play high enough to win โ no higher. "Low to be safe" hands declarer tricks he was never owed |
| Which high card | A message: low with a marked doubleton; the jack from Q-J-10-x; the bold Q or K when you need speed |
| The jack from K-J-x | Discovery + safety + deception โ learn if declarer holds A-Q or the bare ace, and tell partner whether a later underlead is safe |
| Finesse against PARTNER | With A-Q or A-J, finesse the lower honour โ keep the ace as a later entry to partner's suit |
| Question | Answer |
|---|---|
| Why cover | An honour led towards you โ cover to promote a lower card (yours or partner's) into a winner |
| Promotion impossible? | Don't cover โ you'd only hand declarer a card he didn't have. Count what remains first |
| Unsupported single honour | Nothing waiting to be promoted โ don't cover |
| Trick one, unclear | Declining to cover can be the active choice โ it lets the defence's own distribution reveal itself for free |
| Point | Detail |
|---|---|
| You can block your own suit | Top card in your hand, length in partner's, no way back = his winners stranded |
| Unblock early | Play your high card before it's strictly needed, so the suit runs from the long hand |
| Discard in order | Shed first the card you couldn't get rid of later; keep the ones that cost nothing to hold |
| Ask least of partner | Prefer a defence that works whatever he holds over one that needs him to guess right |
| Stretch: hold up J-x | Over a long, entry-short dummy suit, ducking smoothly can kill it โ K, Q, J are equal here, so the hold-up card is the one that best deceives |
