A book I read back in the '70s - a couple of times - by the Russian Nicolai Krogius, I forget the exact title (help!) - something like "Chess Psychology."
Chapters on the psychology of blunders, playing in time trouble, playing in your opponent's time trouble, etc. etc. Very informative and I found it very entertaining as well.
