On the chess24 English broadcasts, Howell/Houska/Snare is aimed more at the general audience, while Polgar/Giri targets the "chess nerds".
So far the match is much more exciting than I expected. MC is taking a lot of risk and sacrificing material rather than playing for dry technical positions. Surprising to me, as I consider Nepo the better tactician.
In this age of exhaustive neural-network computer opening preparation, there seems to be a bit of gamesmanship going on. Perhaps MC is choosing lines that aren't "the engine's first choice" but give JN more opportunity to go wrong.
Delighted to see GM Michael Adams annotating the games for Chessbase, albeit one day after the fact. I've enjoyed GM Sam Shankland's same-day annotations at chess.com; he's worked as a second for MC, so has some insight into behind-the-scenes aspects.
