fk london system
I want to try out London System. Any tips?

Hi! I think the London System is playable - I play it myself too. I would recommend it mainly for experienced players.
If you are interested in building an opening repertoire, I wrote some posts on the subject, you may check out:

Good luck!

It depends on your goal. If your goal is to improve at chess and keep improving to the best of your ability, then I don't recommend it. You should stick to principled classical openings like the Italian, Scotch, Queens Gambit, or Ruy Lopez. The London is not a good opening for chess improvement. If you play chess for fun and just want to learn an opening in 5 minutes then go for it.
I believe players can learn tactical concepts and strategic ideas from any main opening, including the London.
I don't recommend playing the London as one's entire White repertoire (I believe it's important to be exposed to a variety of structures if possible), but there's nothing wrong with focusing on the London for the time being, while learning its various concepts.
Most players stick with chess for the long haul, and change their opening preferences over the years. So one's repertoire tends to naturally grow and expand outward ... so there's no harm in focusing on a specific system for a short time, while learning it.
Other openings will eventually get slotted into the toolbelt, along the way.
Personally, I like to play the London as part of a larger repertoire that includes other White openings. The London's a principled and logical approach, with some unique and interesting ideas ...
Everyone who downvoted my post. What did I say wrong?
