I've been playing chess titans quite a bit! The undo option is great for a beginner such as myself, as it allows me to see my mistakes. I only move up a level when I beat the computer a few times in a row as both white and black without using the undo button though. I am at level four right now.
I've played my brother on
http://www.itsyourturn.com/ a couple of times but he hammered me, 20 to 30 moves and done (he has a phd in physics and has been playing chess for years.) Any other beginners here who play on itsyourturn? If so, my user name is spindaho (don't ask), hit me up for a game.
And sorry to self promote, but I set another chess game to music...I do have a masters in music and worked on my phd for several years so it's not like that silly youtube video with the electronic drum beat and one note at time (has any body else seen that?) I represent each move and possibilities for moves in counterpoint, it's kinda neat. The latest piece is called "Einstein vs. Oppenheimer 1933." and can be heard at
