Felix Blohberger takes on David Navara in Vienna's opening round Monday. The classical format, 90 minutes plus 30-minute increments, favors preparation and endgame technique. Navara enters as the higher-rated player with recent form to match. Blohberger needs a statement result here to announce himself among the elite. The Vienna venue hosts a strong field, making Round 1 a reliable barometer for tournament ambitions.
