Luck

In German the saying goes that if you're unlucky in games, you're lucky in love. Well, like lucky in love, unlucky at cards.
Some people think they get help from a four-leaved clover. The German lottery Lotto advertises with such a clover, I guess wishing the players luck.
Valentine's day is all about the other luck, luck in love.
But I couldn't find a red heart, only the red clover.
