Leading With Long Trumps by Matthias Huberschwiller

A: ♥Q - You must not lead your singleton; you don't want to take ruffs.

Lead your trump sequence instead, to try and prevent declarer from taking ruffs in the short hand.

Your result so far:

A: ♥7 - This time, your trumps are small, and even though you might make a trick with the ♠J, you hope to take multiple ruffs via a Heart lead.

Your result so far:

A: ♥K - With 14 points, you have no chance of getting your partner on lead to give you a Diamond ruff. Lead your Heart sequence instead.

Your result so far:

A: ♦6 - With your four nice Spades, you want to force declarer to ruff. If you can make him ruff twice, you will have more trumps than he does.

Lead your long and strong Diamond suit to try to enact a forcing defense.

Your result so far:

A: ♦5 - You converted your partner's take-out double into a penalty double. That's great.

You need your partner to play Spades through declarer, so don't lead a trump. Since your partner has some values, a Diamond lead rates to be better than a Heart, which could give declarer a finesse he could not take himself with a really weak dummy.

Your result so far:
