Continuing the theme from the last puzzle, try working out whether these auctions call for a passive or an aggressive lead.          (A passive lead would be from a suit such as J 10 8 5 or 10 9 6 3.  An aggressive lead would be from a suit such as K 10 9 4 2 or Q 8 7 3) 

Auction A: 

This is an auction which suggests an aggresive lead- Declarer will propose to draw trumps and use the known good ♣ suit to discard some or all of their losers. We need to grab our winners in ♠ and ♦  while 

we can.

Auction B:

This auction usually suggests a passive lead- most of the strength lies in one hand , and we want to avoid giving away an uneccessary trick, preferring for declarer to do all their own work/guessing. 

Auction C:

It depends on your holding in spades, but this auction normally suggests specifically a trump lead. Most of declarer's extra tricks will be coming from ruffing spades in dummy, and we can reduce that number by leading a trump, even from a holding such as ♦  K 5 3

10 points each for a correct answer- well done if you scored 30!
