Active Vs Passive.

 When the opponents have bid strongly to game they obviously have most of the big guns at least 25 TP. An aggressive lead is called for. You are trying to find partner with a specific card to take the contract down. If the opponents have limped into game then the points are more evenly distributed then there is no hurry to get your tricks let declarer find the missing cards and make the mistakes  A passive lead. is often best.

Leads to Suit Contracts Leads to No Trump Contracts
Aggressive Leads
Top of Sequence (need only be two)
KQxx  QJxx  J10xx  KQx AKQx  KQJxx  QJ10x
Top of interior sequence (ideally 5 card suit)
AQJxx KJ10xx Q109xx
Small from honour Small from honour
Kxxx  Qxx Jxx not Axxx Kxxx  Qxxx  Jxx  Axxx
Singleton/doubleton Singleton/doubleton
Trying to find partners suit
Should have A or Kx of trumps
Doubleton not recommended unless in Partners suit
Passive Leads
From 4 small cards - MUD From 4 small cards - TON
xxxx xxxx
From 3 small cards MUD From 3 small cards - TON
xxx xxx
Lead trump
If you have four of their trumps lead longest suit so that they have to trump a couple of times and you gain trump control

Worst Leads

In order of horror;
1. Lead away from A
Only exception is when you have all four aces This is the worst lead not only because you are setting up declarers KQ but also you are lying to your partner.
 2. Leading an unsupported A
Sets up cards for declarer even if partner has bid the suit is no guarantee that he has the K.
3. Leading away from tenace
AQX KJxx - If you lead suit you give declarer the missing card as a trick if he leads the suit or partners leads the suit you take his honour
