alpha zero showed the berlin is tough to crack if you play e4
1. d4 good for me.
What is Berlin southsidesavage?
e4 e5 Nf3 Nc6 Bb5 Nf6
I play both like the top seed. This would also be my training‘s recommendation.
KID.............. for a change...............
I'm learning the KID for real... so much theory and lines... but i started to play it and i'm loving it. I switched from slav to KID in lichess and i'll give it a try for real otb soon.
Nimzo against d4
Lol everyone is reading the title and not what the OP actually said
e4 is not a legal move, if his opponent has played 1. e4
