What is this opening and it's weakness


Overall, it may not be the soundest opening choice, but if you feel comfortable with it, do play it. The move probably won’t lose you the game, but you got to keep an eye on that d4 square. Black will likely focus his attacks on the kingside, while White can try for an attack on either the kingside or queenside (though preferably the queenside because of the established c4-pawn).
There are very few books on this opening (in fact, I couldn’t find one), and it has not experienced much coverage on the internet. This could be an advantage or a disadvantage, depending on how you look at it. You will have to make the repertoire on your own, but few will know your plans beforehand! Even if Black prepares enough to fight this opening, their advantage will be slim, almost dismal if you become adept at handling the positions!
I wish you luck on your chess adventures! =D
No. There is no strategic or tactical point to the opening so Black has nothing to "fight" against. Even a 1400 player playing natural moves will have better chances or at least equal by the middle game. Black has any number of ways to reply so preparation won't help white much, You shouldn't advise him to continue with this opening.
