I had also many troubles with this fight. Eventually I won with very simple scheme: Ard, imediately when you can (so he can't use first quen). Then strong hits. Prefereably pushnig him to the corner/walls. As soon as he starts recovering, then next Ard and again strong blows. If vigour ends, run in circles while it recovers (in fact not run, but roll, since it looks faster for me
). As soon as you have vogour back and he is not in quen then ard and repeat with strong blows.
This helped me to finish him in two tries (I'm playing normal difficulty).
Didn't used quen myself, because all vigour went to ard.
