Or did Bronstein feel free to finally tell the truth after all these years?
I have ordered his book: http://www.amazon.com/Secret-Notes-David-Bronstein/dp/3283004641/ref=sr_1_1?s=books&ie=UTF8&qid=1443963738&sr=1-1&keywords=david+bronstein+chess+secret+notes
I should say that Bronstein is a notorious liar.
