Play Against Computer

Well, sometimes I make a well intentioned blunder and would like to continue the game using another line to see what would have happened.
Does anyone know what the rating of the computer is on its various skill levels. Just an approximation woudl be helpful.

I think I've heard that little chess partner is ~1800 playing strength on hard? It's not all that strong, but there are several good UCI engines that you can use that allow you to take back poor moves and re-start if you're interested in going that route.

I just started playing chess and have been playing the computer on easy. I lose most of the time, but i was wondering what the approximate ratings on easy medium and hard were as well?

A great feature would be to allow you take back a move. Sometimes I'm in the middle of a great game and accidentally move a piece or blunder and there's no way to undo it and learn some valuable lessons from the position.
There is an option for upgraded players. It is called exactly like that , a "take back " game. Unrated , of course and it means exactly that, you can take back the other player's move, and consequently, yours. It implies trust . Gallons of it.

Does anyone know what strength the computer is on its easiest level?
I'm more or less a beginner, but I am beating the easy level about 40% of the time and was wondering what rating that might translate into.
