For 1 b3 Nf6, Jobava doesnt play 3 Nc3, but 3 c4 double financetto....which is no longer 'Larsen'....but a weak Bg2 opening.
As far as "analysis" goes, the internet is filled with pretenders with low strategy scores. Like if you dont play bullet style you are now a clown....or is this Lyudmil's secret chess? Who knows and who cares.
He at least played that line once in a blitz game. Don't blame me if I'm wrong.
The first game that I played against the Larsen's gave me a very poor opinion of this opening.
Of course, my opponent played very poorly.
3.e3 and white must be at least equal. After 3...Nc6 4.Bb5 Bd7 5.f4 white has a slightly better position.
