Until you are at least a high Class A player (1900):
“Your first name is “Tactics”, your middle name is “Tactics”, and your last name is “Tactics”. You can overcome a weak opening and be so far ahead in material that the endgame is mopping up. I demand that you get every book on tactics and combinations that you can afford and study it as if your life depended on it! Also, there is nothing like a complete game to school you in these tactics as well as the rest of the elements of chess.”
In my view, Kenneth Smith is right about tactics aka puzzles.
Fortunately these days, we have Puzzle Rush Survival.
Tactics/puzzles, particularly Puzzle Rush Survival, are extremely benefical for me.
