Yes, but also keep in mind Ian has a lot of agency. Throughout the first 6 games, he has had moments to make the games more chaotic, increasing the chances of one side having an advantage, and thus far he has almost always played calmer, less chaotic moves.

Now he will likely have to change tactics and enter into more aggressive and risky ideas. It should increase the odds of a decisive result one way or the other going forward, regardless of whether Magnus is "playing for a draw" or not.

More or less yes, except it's 9 more games. The match ends if someone reaches 7.5 points, and Magnus now has 3, so with 9 more draws he wins the match by 7.5 to 6.5. Going into the last game the score is 7-6 so if Nepo wins then the match is tied and goes into tiebreaks.

CORRECTION (see below): this was game 6, not game 5 (I had lost count), so current score is 3.5 to 2.5, and there are potentially 8 classical games left.
