These are offbeat openings which is good and you chose to play the same setup (Bird/Dutch) with both colours which cuts down the theory and has similar ideas. This is a good approach if you can't study a bunch of theory but obviously they're not rock solid opening that will allow you to peruse an advantage out of the opening, more so just a playable position. These will be fine until 1800 for sure but you'll likely have to learn main line theory eventually to further improve past 2000. I would say systematic openings limit your improvement in the long haul, but that's just my two cents.
Opening Choice
Sort:
I have a classical otb rating of 1406 after fide changes. I have choose Leningrad Dutch, Brave Bird Opening and Caro-Kann as my opening choices. Let me know if I can proceed with those changes until I reach a certain level like 1800 rating. I am a working professional. I don't want to spend too much time studying opening at this level. Please suggest me some opening which will give a healthy chance to me also will be a surprise for the opponent ( So that opening prep will be out of question ). I have also choose the Leningrad Dutch ( Chessable ) for black and Brave Bird Opening ( chessable ) for white since they look similar.
