Chess Puzzles: World Champions

I purchased this app for .99 and I can honestly say that it doesn't get better than this. The chess computer sometimes moves different than the original game, which is great--sometimes I can solve one, redo it, and take a while to figure out based on the other move it made. Chess books as great, but this tops them all and it's dirt cheap. Another plus, for me, is the custom skin options. I love the Leipzig pieces on gray background. It's so awesome and I wish my other chess apps had those pieces. The next best app is tchess. I was hesitant, but the computer and analyser are AMAZINGLY helpful. Spread the word for these great chess apps!
