Turn based games like chess or card games

I am a user of PUN.
I am trying to make a turn based game like chess or card games.

I already checked the code of Rock Paper Scissors Demo.
PunTurnManager worked as expected in Rock Paper Scissors.

In this demo all of turns will proceed simultaneously.
But in a general turn based game each player operates separately.

I think that it is necessary to add the following processing.
I will set who's turn in PunTurnManager.

ex
public PhotonPlayer GetWhoseTurn();
public bool IsMyTurn();
etc...

Then if it is not my turn, I will end the turn.

But, I think this is a NOT beautiful logic.
Is there a good strategy for this case?
