thanks. I thought i was missing something. Thanks for clarifying

Recently a declarer claimed the remainder of the tricks. At that point, all 4 hands were shown. I saw that declarer could claim if she knew to play a particular card from dummy. Seeing all 4 hands, it would be obvious to play that card, but without seeing how the cards lay, she would have a decision to make. It seemed to me that claiming showed her the correct line of play. Am I missing something?
