The line with 10.h4 is pretty weird, but I have seen many players use it so I dont think it is busted.
Best line in Jobava-Prie Attack

I think you should go for it if the 2260 is significantly better when playing mainlines and known structures for him, and I think you should go with your normal stuff if you dont think playing this funky line will affect his strenght.

The Jobava Attack is discussed extensively in Chapter 8 of "The Agile London System" by Alfonso Romero & Oscar de Prado (New In Chess, 2016).
There are 3 primary games, analyzed-annotated in detail, featuring this attack as follows:
1.d4 Nf6 2.Nc3 d5 3.Bf4 etc....
A) for 3...a6 - Baadur Jobava - Boris Savchenko Minsk 2014 (5)
(Notes to the game above succinctly examine several games, featuring 3...e6, 3...c6, and 3...g6 - all apparently as secondary sidelines. Of these, the authors comment that 3...e6 is a very solid and popular alternative.)
B) for 3...Bf5 - Baadur Jobava - Shakhriyar Mamedyarov Dubai 2014 (3)
C) for 3...c5 - Richard Rapport - Emil Sutovsky Tromse 2014 (9)
In the analysis of these games, the authors do not appear to have recommended any of Black's responses as superior to any of the others (although I have not examined the analysis in detail).

He knows I play london so I need to variate
Play 1.e4 then, LOL!
What does he play against the Queen's Gambits? Have you thought about hitting him hard with a minority attack if he plays the QGD? Safe not to get destroyed, and if your attack suceeds you can have fun pushing in the endgame.
on principal it's not a good idea to block your c-pawn with your knight in a queen's pawn opening. Since you obviously know this this will probably not be a good argument against your case. However I would still advise against your opening choice: as your opponent is stronger (based on your blitz rating on this site, correct me if i'm wrong), chances are that playing unprincipled in an opening you have never played before will do you little good. I would suggest playing what you know, even if he knows what you play. The london is known for the solid positions and thus a very small edge for white going into the middlegame. Given you have the most experience in london type positions this should be enough to get you a comfortable middlegame. Playing a (very slightly) inferior line against tougher opposition never seemed a good idea to me, as the chances that the opponent will be surprised are lower if the rating goes up. This goes especially if you have 0 playing experience in the surprise opening.

What do you mean by deep prep, I dont think studying "theory" will help you much with the Jobava, you would do best analyzing games from Jobava and Rapport IMHO.

So basically what you are looking for is to put both you and your opponent in a weird middlegame you dont understand and hope he understands it less?
Looks reasonable, probably the adrenaline will kill you tho.

Nice addition to the London system.

thanks for the games
What is blacks best move after Bf4? I will try this line versus a 2260 in a club championship and I´m trying to find out which line is the best to play. I know Jobava is a creative player but are his line playable If white is striving for an advantage? All answers are appreciated
Firstly, it's not the Jobava-Prie attack, or the Jobava line or any other opening with Jobava's name in it, and as far as I know Jobava has never claimed it is. The correct name for the opening is Mark's Opening.
Bf5 is probably the best 3rd move for black.
With the c5 line, white is probably better playing 5 Nb5, rather than immediately taking the pawn, threatening Nc7, forcing black to put his knight on the edge of the board on a6.
