THE TRUMP LEAD AGAINST A SPADE MAKE
As a rule, the aggressive spirit that should characterise the non-dealer’s play of a spade hand is lacking. While a spade is not necessarily made from weakness, the declaration in itself shows sufficient weakness in the side suits to embolden the adversaries’ play. With a hand containing five trumps (spades) the initial opening should be the trump. Your partner must hold suit strength which your trump lead will protect.
If your five trumps contain a tenace and you can advantageously lead from another suit, it may be advisable to wait for your partner to lead to your tenace, particularly if by doubling you have indicated trump strength.
If you have been redoubled and your hand contains four trumps and strength in the side suits, the trump lead requires more careful consideration.
Unless your partner has doubled the spade declaration it is impossible for you to place the trump strength, and you should be cautious about leading originally from a short trump suit.
