Hikaru quit after 2 bullet games vs Yaacov saying he was frustrated. He just had had a bullet session with Riki and said his style of play annoys him. Thats all I know. He might have said more, Idk.
That session Naka vs Riki. Naka won 14 - 2
Where is proof that Naka was frustrated? He just destroyed Riki? Your only intention is to de-rail this posting with unfounded information.
Bonaparti, you need to watch Hikaru more often. I think this was your first time.
