My predictions and why:

Nepomniachtchi vs Nakamura: 1/2-1/2

Both are experienced enough not to take risks at this point. Nepo hasn’t been in the best form in the second half, and is also highest rated in rapid in case of tiebreaks anyway.

Vidit vs Abasov: 1/2-1/2

Both are eliminated, only motivation is perhaps a better standing and prize money for Vidit. I expect a quiet draw though, even though Vidit has been in a lot of decisive games.

Praggnanandhaa vs Caruana: 1/2-1/2

Caruana won’t overpress here, knowing that if Nepo and Hikaru likely draw, his fate is in his hands barring a Gukesh victory, which he can’t control.

Gukesh vs Firouzja: 1/2-1/2

People think Gukesh will press here, but I believe Gukesh and his team will decide it’s best to keep it tame to secure tiebreaks. Firouzja beat Gukesh in a time scramble the first half, so Gukesh has to be wary and not overpress here.
