Best for study – Simple chess board Review

While the interface is not pretty, this is the best chess app I could find on the App Store for study purposes. Other more polished apps with chess engines are terrible for many study purposes due to their inability to allow illegal moves and insistence on making the user play the computer. When having a chess book open and needing to study an example, many times I have needed to setup an illegal position. This app was the only one I could find for this purpose.
