Partner led the  7; how thoughtful that partner led your singleton! (Your partnership leads are fourth best from power and second best from three or more spot cards.) Declarer played the  K from dummy, you followed low, and declarer played the  9 from hand.

Then declarer calls for the  Q from dummy. Which heart do you play?

ANSWER: Play the  4, not the  2, beginning a high-low sequence in trump; at your next opportunity you'll play the  2. This standard sequence will show partner that you have a third trump card and want a diamond ruff!

THE PRINCIPLE: A trump echo -- playing high-low in trump -- specifically shows at least one more trump and a desire to ruff. Even if declarer draws two rounds of trump, partner will know that you still have a trump remaining and want to ruff a side suit.

If both you and dummy are short in the same suit, only give a trump echo when you can overruff dummy. Also, you will infrequently run into a situation where you don't want a ruff even though it is available; by playing your trumps up-the-line you can indicate your lack of enthusiasm for a ruffing defense.

A note of caution: do not use the trump echo unless you have a ready ruff in a side suit. Because declarer also knows that your echo shows a third trump, declarer will sometimes then know to fell a doubleton queen from partner's hand. So only reveal that information when there is a clear reward available.

One way to remember this is that playing high-low always shows a desire to ruff. Playing high-low in a side suit shows a doubleton and a desire to ruff that suit; playing high-low in trumps shows a desire to ruff some side suit. In either case, you promise a trump to ruff with!

Lastly, a note from the Department of Dogs That Didn't Bark: A corollary to the trump echo is that if partner does not give a high-low in trumps, then she either does not have a third trump card or does not want a ruff. For example, if you're wondering whether partner started with a singleton or a doubleton in a side suit (after playing only one round in that suit), her failure to give a trump echo would suggest she still has a card remaining in the side suit.

We'll continue with this deal in the next episode; stay tuned!
