Svidler and Grischuk at chess24.com are fantastic, but they're both world class players and beginners will find their commentary and analysis difficult to follow. I'd recommend chess.com - Danny Rensch and Robert Hess are a bit more accessible.

I second chess.com. And the guests they have, Hou Yifan and MVL today, absolutely elite players. Yet they manage to keep them understandable.
