print(state.is_simultaneous_node())    # Output: False

game = pyspiel.load_game("matrix_mp")
state = game.new_initial_state()
print(state.is_simultaneous_node())    # Output: True

# Simultaneous-move game that start at a chance node.
game = pyspiel.load_game("markov_soccer")
state = game.new_initial_state()
print(state.is_simultaneous_node())    # Output: False
print(state.legal_actions())
state.apply_action(state.legal_actions()[0])   # Apply first legal chance outcome.
print(state.is_simultaneous_node())    # Output: True
