Decide on the suit first and then the
card.
Against suit contracts you can select a suit
because
- Your partner bid
it
Lead your largest
- You are strong in
it
Lead the top of touching honours
- You are short and may get a
rough Hi-lo with a doubleton
- To lead through dummy's
strength Middle-up-down with 3 or
second highest with more
- They have lots of
trumps
Lead a low trump as a "safe" lea
Against a no trump contract
- Your partner bid
it
Lead your largest
- You are strong in
it
Lead the 4th highest
In general only lead an ace if
- You have the king
- It is a singleton or doubleton
- It is trumps and you intend to follow with another trump to
reduce their trumps.
Cheers,
