What is Naka doing?

Recently Hikaru Nakamura has not being doing so well, as prior to the Isle of Man tournament, he had not won a game since Round 1 of the Olympiad. Even though right now he is 3/4 in Isle of Man, his most recent win should have been a loss. Is he just succumbing to time as he is now 30, or is it something else?

Looks like he is turning into Gata Kamsky...

Players have good and bad periods

Completely agreed, I feel like all of us have them at some point or another, I just didn't see it coming with Naka. 

Yes, Naka has been slipping a bit last few years. But his performance in the Olympiad was very disappointing, I agree. He finished +0. On board three no less.

Naka is spozed a match for the best player any country can produce. Let alone their third best player.

Thank goodness Fabi, So, Shankland and Robson all performed well. Or we never would have taken silver.

Yeah, I super glad that we had the others to carry Naka's dead weight in the olympaid, If he had won one or two more games, the US easily could have won gold.

Even Naka's bullet and blitz has taken a slip.

Take a look at the Leaderboards for Blitz and Bullet the past few months and you can see that he has been overtaken many times now by other upstarts even though he was a very solid number 1 in both the Blitz and Bullet ratings for Chess.com (apart from Magnus Carlsen).

If he is number one now, it is because those who overtook him faltered and went down in rating. But not long ago, he was permanently number one in both Blitz/Bullet ever since I remember, and nobody could ever come close. He always had like a 100 point gap between himself and number two.

So was having an amazing Olympiad the first 7 rounds. But then he tapered off, due to lack of a rest day. They didnt dare move Naka up to board 2.
