When one opponent can do damage to your (notrump) contract, but the other opponent cannot, you must focus on losing the lead to the safe hand.
Exercise: Say West is the danger hand. Play the following suits to try to avoid him winning the lead.
| (a) | (b) | (c) |
| North | North | North |
| A J 3 2 | 8 6 3 | K 9 4 2 |
| South | South | South |
| K 10 9 8 | A K J 5 2 | A J 7 5 |
(a) Lead the king and run the ten. If West holds the queen, you have not lost a trick; if East holds the queen, the finesse has lost to the safe hand.
(b) Cash the ace-king to catch a doubleton queen in West’s hand. If both follow low, lead a third round in the hope that East holds the queen.
(c) Cash the ace, then lead low to North’s nine. You only lose a trick to West when he holds Q10x or better.

What happened?
Declarer correctly ducked ♠ K lead, then ♠ Q, and won ♠ A on the third round. This had the desired effect of exhausting East of spades (he knows this from West’s overcall in the suit – promising five cards).
At Trick Four declarer cashed ♦ A but, knowing that the best odds to avoid losing a trick to ♦ Q was a finesse, crossed to ♥ Q and led back to ♦ J. Oops! West won ♦ Q and cashed two more spades. Down one.
What should have happened?
Declarer only needed four diamond tricks so could afford to lose a trick provided it was to East (who, thanks to holding up ♠ A until the third round, held no more spades). So cash ♦ AK at Tricks Four and Five. On the actual hand West’s ♦ Q drops, promoting ♦ J42, and ten tricks are made. If only low diamonds appear under ♦ AK, lead a third round in the hope that East holds ♦ Q.
Tip: Look for ways to prevent the danger hand from winning the lead.
