|Cavaliers are worth 3 points each and
are good to keep; however, don't be afraid to sacrifice them if you're main goal for the
game is to bleed Tarocks.
Not many players pay much attention to the Cavalier, making it a good card to dish to your partner, giving her points without drawing too much attention to yourself, before everyone has figured out who has the called King.
Be on the lookout for the player who dishes a Cavalier to the declarer and then plays a lower point card of the same suit on the trick you've just trumped; chances are that played holds the called King.
From this, you'll know the remaining player is your partner allowing you, then, to dish points to the proper player.
