Whats so hard ? If they play Bc5 you okay C3 and D4 If they play the Steinitz (D6) you push D4, same for Jaenisch Gambit (F5) If they play Berlin, you play the Rook E1 Anti Berlin Whats so hard about that ?
I need help pushing to 2000

Many amateurs play the Cozio (Nge7) and the fianchetto (G6) Then Nc3, D4 and opposite castle to punish that and easy wins

yeah ameteur... i definitely dont play the cozio

An E4 player not playing the Ruy Lopez is like a D4 player that doesnt play the Queens Gambit It just doesnt make sense

You should create an opening repertoire first, then learn the Middlegame ideas and learn how to calculate variations
the theory on that opening is almost impossable
