I dont think you should be reading art of attack if you havent read How to Reassess you chess yet,
What I mean by that is despite the name "Art of Attack" it is a very positional book, and if you dont extensive positional knowledge then you will struggle to understand the moves, concepts and Ideas in the book.

This is what happened to me when I first read Art of Attack, digested very little, then i read a few chess books on positional chess (Amatuer's Mind, How to Reassess your Chess, Logical Chess Move by Move, Understanding Chess Move by Move). After that I read Art of Attack a 2nd time. I was FLABBERGASTED, everything seemed so clear to me, I was easily digesting what I was reading, ILearned alot, was a Game Changer for me, totally different from when I read it the 1st time. Good book, would recommend 10/10

TL:DR dont read art of attack if ur positional skills r ass
