If you hold a sequence of three high cards in the combined hands,
while, of course, it is better form to lead from the weak hand,
it makes but little difference from which hand the suit is led.
Therefore, if you cannot conveniently place the lead, do not hesitate
to lead from the strong hand. Should you, however, hold a sequence
of two high cards in one hand with small cards in the other, for
instance:
+------------------+-------------------+
| _In One Hand._ | _In the Other._ |
+------------------+-------------------+
| K Q x | x x x |
| Q J x | x x x |
+------------------+-------------------+
it is always advisable to lead from the weak hand. Should the queen
win in the first combination, wait until you can again lead the suit
from the weak hand.
