get a premium lesson on the modern defense/system

Hmm, who told you that the two knights variation was bad?
Even without playing 5 a4, your opponents do quite well against it.

I like the modern in that it offers imbalance and it can get very sharp.

As a beginner, forfeiting the whole central board to white is a recipe for disaster when you don’t know the timely move orders and thematic breaks.

Hey man I wasn’t insulting you. My bad if that’s what it sounds like. I like the modern defence and my previous comments are from my experiences.
I went from scoring 30% winning with the QGD to 50% with the Modern and Englund Gambit against d4.

GM Aman Hambleton is doing a speed run with Fianchetto systems as white and black. So you will see the modern, English Defence, English Opening and Queens Indian Attack in play.

Playing anything faster than 5/5 and my playing strength takes a huge dip. I would recommend playing time increments because the increment bonus is a life preserver in the end game when you are ahead. I lose quite a bit as well due to flagging but that is part of the game. I’ll still play bullet and blitz to practice my openings and tactics.
There isn’t too much theory in the Modern Defense but it helps immensely if you know other systems say like the Sicilian Dragon because then you will see the themes, ideas, weaknesses and strengths for both sides when they transpose.
At the beginner level, it’s easy to snipe a center pawn with the fianchetto bishop lol
