I've recently started a new project, where I record a top level Australian dueller (ELO 2000+, most vids by ~2300 elo player, Fraze), who duels while thinking out loud. Its great to see what goes on in their head while they're playing.

I also get them to focus on specific things, like how to play out of control.
