So if it is your turn to lead and no heart has been played yet then you may not select a heart as the card to play first. You cannot lead a trick with hearts, until hearts has been broken (played on another suit).The player who has the two of clubs at the start of the game leads in the first hand, and he MUST lead with the two of clubs.So you want to avoid taking any tricks that have hearts or the queen of spades. Any penalty cards in the trick (hearts or queen of spades) are added to the players penalty score. he takes the four cards on the table and he then starts the next turn. Once four cards have been played, the player who played the highest ranking card in the original suit takes the trick, i.e. If they don't then they can play one of their other cards. If they have a card in the same suit as the first card then they must play that. The other players then play one card each.
The suit of that card determines the suit of the trick.
