"""A Most Basic Hanabi player

Most Basic Players only play if they know for certain that a card is
playable.  Otherwise, if there are hints available and another player
has a playable card, Basic will give a random hint about that card.
Otherwise, they discard randomly.
Basic players can only handle rainbow as an ordinary 6th suit.
