Let's say I'm holding in S1.





Dealer just orders up a club, lets say

Do I lead the weak


I see it play out both ways, but most recently I short suited myself, S2 takes the trick and as the hand plays out ended up both had a diamond in their hand.
Conversely, I've played the other way, had my weak Ace trumped and then lost my trump to the Right.
Is this a 50/50 thing? Gut feeling?
