Instance Method Details

#play(top_card) ⇒ Object

Select one or more of our cards (according to our playing strategy)

Note the the player has no further knowledge about the state of the game except the topmost card of the pile that is passed. If a player wants to implement more advanced strategies (e.g. by observing and counting the cards already played), we need to implement a notification mechanism that tells every player which card the current player played.

TODO Need to obey if top_card is a trump, unless we can trump that one TODO If the game system allows it, return two identical cards
