Playing with yourself?

I would suggest that you 'play yourself', rather than play WITH yourself. That way, you can avoid any unfortunate misunderstandings. You could of course do both at the same time, although I imagine it would be difficult to concentrate properly on either activity...

No, it won't make you go blind - it may possibly give you repetitive strain injury. Is anyone else finding it more and more difficult to see these discussion threads...

Brilliant!
Can you get good at chess by playing with yourself, or is it better to have an engine or human player?
