I couldn't agree more.

Opening study (along with study of my own classical games and occasionally master games and playing rapid blindfold games) are the core of my training and I improved from 1800 to 1930 FIDE in the last 10 months. For comparison: in the previous 13 years I was improving by 15 points at average yearly while doing insane amount of tactical training (but still losing usually due to tactical blunders...).

The notion that amateur players lose usually by tactics is partially correct but somewhat misleading. Often poor opening play or poor strategic play in the middle game is leading to situations when a player has no tactical chances while the opponent has many. Finally one cracks in such a difficult position and an engine happily points out a tactical blunder. But the real trouble often starts 5-15 moves before and while a position can still be equal for an engine, it is definitely not equal for a human (especially amateur) player.

I see the following advantages of opening study at my level (1900 FIDE, 1900 chess.com, 2130 classical lichess):

- Finally I am done with constant time trouble. In the past I had a huge fraction of my classical games lost in time trouble due to simple mistakes. Now after the opening I usually have 15-20 minutes clock advantage (in 90+30 games). This clock advantage usually is reduced in later stages of the game when I invest it in calculation.

- I play moves that I would never even consider playing if an opening course didn't show me that they made sense. E.g. willingly letting my pawns got doubled and showing me what to do with them. Or sacrificing a pawn for strategic reasons.

- Even when I am out of theory, I usually know what kind of moves, pawn structures and piece placement make sense in particular openings. I just need to double-check if they still work in a specific position.

Another point in favor of memorizing openings: it's SO EASY. Spend 5 minutes a day on Chessbook and you can have hundreds of moves memorized within a few weeks.
