Is there anyone capable of adopting Hikaru Nakamura in blitz matches?

Only engines such as Stockfish Classic, Leela Chess Zero, or Komodo are capable of adopting Nakamura in blitz. No human player would be in contention considering that Nakamura is the best blitz player in the world at the time of writing.

I like to dump on Naka because his streams are annoying...
... but I have to say his skill is obviously (nearly) unmatched. When Naka is in form, I've only seen Carlsen match him. Everyone else is demolished. Everyone.
So adopting is out of the question. Only a severely handicapped Naka or an engine opponent will result in 10 straight losses.
Totally agree about adopting, but with both on them in form, I'd bet on Carlsen for the win anytime.

NOT even a single draw !? Definitely not !
Adobting him (out of 10 games not letting him win a single game ) I would say Magnus can do it : pay him 1 million $ and tell him not to loose a single game , he will adopt him by getting all the games dry and going for a draw, waiting for an opportunity for Naka to make a mistake then go for a kill.

And peak Tigran V. would give him a run for his money.

The only way most likely:

Peak Magnus might be able to.
The Magnus of the past few months, though? He'd be more likely to be adopted by Hikaru.
But to answer the OP: No, I don't think anyone is currently capable of adopting Hikaru in blitz.
I think Wesley So, though, is capable of making Hikaru really struggle in blitz. Even more so than Magnus.
When Hikaru played Wesley in the recent Speed Championship, Hikaru was milking the clock, trying to limit the number of blitz games so he could get to the bullet games quicker . . . because Wesley is so strong in blitz.
Can you name any players who are capable of straight up beating Hikaru 10 times in a row with Naka not even being able to get a draw?
