Btw, you may also switch to a Rubik's cube as well
I think it is a joke concerning his profile picture, but if it is serious, no it's not a good idea, Rubik's cube is as difficult mentaly as chess, if not worse, because sometimes you are slow and have no idea why whereas in chess you can analyse what you did wrong
solving a rubixs cube is mostly just pattern recognition and muscle memory assuming you know how to solve one. Learning to solve one by yourself is a mental challenge that nobody would be able to solve in a reasonable amount of time(the inventor himself took a month to figure out how.
