Blindfold Chess, who as tried it themselves, I have always been fascinated especially those masters who can play 20÷ boards ar same time!? I have played single games and successfully played them to the end, I have done this on the site called SchemingMind they have an option you get a Blank Board and Move by your opponents is shown in Algebraic Notation it's very good exercise for visualisation, played total of four games over last 18 months. I have seen a couple of exerbition Blindfold Displays the most famous breathtaking display was by the Legend Mikhail Tal who took on 46 borads amazing to see and I arranged a blind fold display at my own chess club with I.M Paul Littlewood who took on 26 boards please share your own thoughts and experiences👍
