"Pawn Structure Chess" by Andy Soltis.... best book ever, it takes time to go through thoroughly though. It really teaches you about squares, strategy and planning and how the pieces should work in various pawn structures. With every chapter, find master games in those positions as supplements.Please be relevant, helpful & nice!
Thanks for the recommendation, I'll certainly check it out.
Konan, any chance you may be overthinking? I only ask because of your example of the Q blunder and illusions.
It may indeed be possible that I am overcomplicating things instead of just playing simple chess. Or perhaps I am too trusting of my opponent's moves. The opponent who blundered his Queen was higher rated than me, so there could have been a psychological aspect to my blindness.
