I just played a game of Spades with some family. The Ace of clubs was led on the first trick, and I was out of clubs. Needing quite a few tricks, I chose to trump. My fellow players instantly responded with complaints about a rule that the first trick cannot be trumped.
Obviously, house rules can always be in play. My question is whether this is a common rule to play by, or if this is relatively unheard of. I've been unable to find any sources online that indicate forbidding this action. Is this a common rule to play by?
Mainly I'm looking for grounds for opening the next game with stating explicitly, "Trumping the first trick is legal, as long as you meet the normal requirements," hopefully adding, "That is the way almost everyone plays," to avoid this sort of dispute again.
