It's not crazy to play chess with yourself, we do it all the time

Only if you use the practice board in the Live Chess part of chess.com and keep clicking off and going back onto it everytime.

No need to throw in a random, unless that's what you'd do in a regular game.

Sounds annoying... but I might.  

Play myself & randomly too!

What happens when you throw in a random is that it could turn out to be a bad move, which allows the other side to gain an advantage.

Absolutely, but part of the game is learning to cope with the random & being able to recover the game   At least I think it is.

Thats true. Sure you might be a piece or a pawn down but always try to build up the momentum to your advantage. Try to maybe sacrifice a piece here, move a piece there and then boom, you have the advantage, or you lose. LOL.

 I've got as far as recognising my own strategy!  I often doggedly stick to a move that would be excellent if....if ONLY the other player moved where I expected(wanted) them to move.  It would sort of be fun to try out my ideal game though....

I think coping with the random should've happened early on when a person is learning the game. One never knows what to expect from beginners because they most likely hadn't learned openings.

Even with random moves/sacrifices, they should have some calculations behind it. 

@Marcosite - Since you'd be playing against yourself, you do realize you'd hardly be moving to where you'd expect yourself to move. It wouldn't be much of a game if that happened too often.

I can't play chess against myself. Totally impossible. It must be wrong to say you're playing against yourself. Calculating moves is different than playing against yourself, in my view.

Extremely tedious. Playing against computer is GREAT and very challenging. NOTICE how the computer moves BLOCK the opponents moves . ITS AMAZING  You cant get ahead whatever piece you try to move the computer has you in a bind. I ASK myself if a computer can make such fantastic defences SO SHOULD I............but alas i fail

Is talking to yourself the same error in linguistic expression as saying you're playing against yourself? I think it may be.

I had to give up studying chess at the library because of this.  Not that I made a big deal of it, just a magnetic folder and a couple of books, but every tenth person who went by was reading from the same script: "Whatcha doing there buddy?  Playing with yourself?" followed by gails of near demonic laughter.

EDIT  Actually it's kind of fun to try out different lines from a database although I've never really elevated it from study to contest.  Seems like a sure way to get a couple of new voices in your head.  No thanks...

When Magnus was young, he played against himself for hours, so it is good to play this way as well!

Go me go!

I`m practicing a cheer in case I play against meeee.

No, obviously not.  In fact, I'd block & parry so much that neither of me would find it a satisfying game but without testing it, I suppose we'll never know!

Is playing blindfold 3+2 blitz against oneself crazy then?

Is the problem the word "against?" I used that word over the other to avoid any demonic laughter that might arise.

@marcosite - If you think that's what you'd do, then it might be worth a try to experiment with a more offensive approach.

...nah...probably not...I don't seem able to focus on the opening game like most chess-players  here.  In fact, I open randomly & often flippantly & my rating, no doubt, highlights this. It's a problem but I can't seem to stop myself! Call me a mid-game person...

Yes, it's different. However, you can play against yourself while calculating moves.

@marcosite - That's fine if you are using a random opening. That just means you'd have to do more calculating early on in the game.
