Why not just study tactics by playing actual games? That at least will assure that the tactics examples you have to solve are realistic, in contrast to the ones you will find in tactics training settings, which are often ludicrously artificial.
This would not work. In actual games you would miss the tactics and learn very little.
you just play more games to increase the amount of tactical knowledge yo gain and again you review and analyze your own games this will work definitely and is way better than tactics
Thats like saying, you should just do more math problems, without actually studying math.
Yes.
Studying tactics can give you new ideas you never thought of before.
I remember studying tactics once as a beginner, came across the most amazing combination. Even had a name. "Smothered mate" they called it.
A week later, I did it to my friend in speed chess. He just sat there staring at it, holding my queen he just snapped, jaw on the floor, not believing it was really mate.
Win positionally, lose tactically.
Much less frustrating than doing it the other way.
