alt Hacker NewsHikaru is either in a slump or his skill is starting to age: hasn't won Titled Tuesday since November, hasn't won Freestyle Friday this year, came last in Speed Chess Championship, etc.
We'll see how well he does in Candidates this year to see if he's still a top contender. Although I do believe this is his last chance to fight for the world title.
To be clear, "came last in Speed Chess Championship" actually means he came in 4th out of 16. He still made it to the semifinals. Even then he barely lost to Alireza, who is pretty universally considered a top 3 speed chess player. The loss to Lazavik was a lot worse, but it was still a close match against a strong player. He hasn't won a Titled Tuesday this year but he hasn't scored worse than 8/11 and he's still made the top 10. That's not as much of a slump as you imply IMO.
