I was playing a round of Love Letter with my friends. When it came to my turn I had a Princess and King. I was forced to play the King and trade the Princess with another player.
My question is, is it legal to then announce to the other players that I had the princess, so it is known that my opponent now has that card? The announcement allows other players to potentially take advantage of this information, saving me from being a target in the next round.
Some of my friends think this violates the spirit of the game, but we couldn't find any rules one way or another. What do you guys think?
