Have had a frustrating evening trying to learn how to play chess properly – on my laptop. Being of an age when I can walk upstairs and forget what I am doing there I hoped that playing chess would improve my memory and perhaps ward off dementia – ever the optimist. Most of the books encourage you to list all of the candidate moves for a given position and calculate variations for each, how do you visualise variations of more than three or four moves? GM's and perhaps good club players do but I can't. Fritz my silicon opponent always wins perhaps I should try my luck against a few human opponents.
