Defensive Tip: Suit Preference
by Thomas Rush

Here's a tip that will make your defense both easier and more accurate. It doesn't come up on every hand, but since you defend about half the time, any improvement on defense can be a huge win!
The tip is this: When leading a suit for partner to ruff, the card you lead to him should be suit preference, that is, suggesting which suit you want partner to lead back to you. The suit you're leading and the trump suit are not in consideration, so that leaves two other suits. Your high spot card calls for the higher suit, your low spot card calls for the lower suit (a middle card says "don't care" or "doesn't matter"). Note: Next month I expect I'll describe a couple of other times you might not have considered, but when suit preference signals can also be used.
Here's the auction from a recent BCoH hand (rotated so that dummy is North and you are East):
S W N E
P P 1S P
1N P 2H P
3C (all pass)
Partner leads the heart 7, and you see:
First, we think (as we should on every hand), "What's going on?" The facts we see include:
- North has opened light in 3rd seat; South is a passed hand responder, so each pair has about half the deck, and our partner is not broke, probably has 10 or 11 HCP.
- South didn't take a preference to spades or pass 2H as we would expect most of the time when he has a doubleton spade (2S) or three hearts (pass)
- Partner's heart 7 doesn't make a lot of sense; we would have expected a diamond on this auction. South 'shouldn't' have three hearts, but we can see all but the A82 of hearts... huh? P wouldn't lead the 7 from 87 or 872, and we don't expect an underlead of the Ace especially given this auction. He could have the 72, and the unexpected would be for him to have a singleton.
- Partner must have length in spades; I have a singleton and South surely would have raised spades with three, so P rates to have at least five, and maybe six spades
- On this auction, we expect South to have a weak hand (of course, if partner has 11, dummy 10, and we have 9, South has 10 or maybe 11) and at least six clubs.
- But the hand's not making a lot of sense, to be honest. So we'll wait and see how things shake out.
In any case, declarer calls for a low heart with little hesitation marking him with the Ace; you play the Ten and South does play the Ace.
Trick 2 is a low diamond from South to the Jack and your Ace.
Trick 3: Not sure of what's going on yet, you lead back a diamond, which your partner wins with the Queen.
Trick 4: Partner returns a spade, King, your Ace, and declarer's 3.
A break for thinking: Partner must have the spade Queen, or declarer would have been working on spades not diamonds (or, better for his side, would have taken a preference to 2S over North's 2H rebid!). Partner's count signal on the diamond showed an even number, so diamonds look like 4432 or 6322. But I'm still confused by the auction and what I've seen so far. In any case, I'm on lead to trick 5. What do I lead from

A club is a possibility, but it's just possible partner has a trump and the opps haven't had the best auction. So let's lead a heart. Which one?
Remember the tip: I can tell partner which suit I want him to return (spades or diamonds) by which heart I lead for him to (I hope!) ruff. The two suits in consideration for my signal are spades and diamonds. The lowest heart is clearly asking for a diamond, and the high heart asking for a club.
On this hand, there's not a lot to choose from, but since I want to make sure we get our diamond tricks and/or make declarer ruff, I asked for a diamond return with the heart 3 -- I also don't want to have declarer overruff me in spades if we both started with singletons.
Trick 5: heart 3, 2, ruff. Sure enough, partner trumps my heart return with the club 2, and
Trick 6: correctly cashes his diamond King (I pitch a heart), and then
Trick 7: with a count on the suit P leads another diamond (his last) for me to ruff. I know now that declarer is ?-3-4-?, where spades are one or two, and clubs are five or four (?!?).
Trick 8: I lead another heart and I'm amazed as partner produces the club Jack to ruff this third round of hearts.
Trick 9: Partner leads the spade 10, which I ruff... and declarer follows. So what's going on? Declarer's shape must have been 2-3-4-4, something like xx, Axx, T9xx, A??x... and partner looks to have one more trump.
Trick 10, I lead my last heart, declarer ruffs with the club Queen, and partner, bless his heart, overruffs with the King!
Trick 11, Partner returns a spade, I ruff low perforce, and declarer overruffs.
Trick 12, Declarer cashes the club Ace, I play my low club, but still have
Trick 13: my club Ten beats declarer's club 4 for our tenth trick, down 6.
Now, this is a hand where declarer was never going to do well in 3C (South's proper call is probably to pass 2H, playing in the known 4-3 and possibly 5-3 fit. Others might take a preference to 2S). Given a jack or so more, South might have rebid 2NT over North's 2H rebid to suggest a NT contract and invite to 3NT. The 3C call, though, should show at least six good clubs, and was not forward going.
The complete hand:
This business of giving suit preference signals when giving partner a ruff is pretty standard. Next month we'll look at a some other suit preference situations that are a bit more advanced, but are still things you should discuss and implement with your regular partners. There's no cost (you're not giving anything up), but the payoff in accurate defense is potentially huge!
