Theodore Lightner

Theodore Lightner invented the idea of doubling a slam to ask for an unusual lead. "Unusual" typically means one of two things:

1. Doubler has a void and wants a ruff.
2. Doubler wants dummy's suit led.

The doubler expects that without alerting his partner to the need for a special lead, the slam will make. Lightner doubles are not alertable.

Say you are on lead after this auction:

YOU	North	East	South
	1	Pass	1
Pass	3	Pass	4NT
Pass	5	Pass	6
Pass	Pass	Dbl	All Pass

You hold: 5
Q J 7
Q 2
10 8 7 6 5 3 2
.  Likely, partner has a club void, so a club lead is indicated.  (It isn't likely a diamond lead is needed based on your hand and the auction).
