When playing white I open with
1e4 and my opponent plays 1 d5
any line in the the 1.d4 d5 colle . ive gotten the moves down to a science from the white side. as for black i love to play against the lopez in the berlin endgame because i know i wont get mated
Personally, it's the Scandinavian. Perhaps it's because my opponents don't know how to play it properly but it gives me little trouble.
Often, you can chase the queen around and develop your pieces at the same time.
