Sometimes you'll hear about or see people playing a game of chess with themself. I don't understand how they do it. Seems doesn't really work if you know exactly what your opponent is doing.  Talk about telepathy... whoa.

iv done it when i have been really bored, i just eventually blundered with one side and thats how the other side won.

If you're really bored, I guess it could come in handy.

pocket billiards maybe ?

Very difficult to mate yourself with pocket billiards.  Seems like you'd be at it all day.  

I like to alternate hands.

Between turns, I mean. It makes it feel like two people are playing.

Always a draw. Kinda weird but yeah.

How do you play with yourself?

Kinda personal, don't you think?

ha ha

I think you would, I don't know, haven't tried it

CAN'T STOP LAUGHING!
