I love the graphics on this program ...by far the best of any program ive seen.
The basic black-and-white is very good however however the geometric chess are, wild and difficult to see on a small iPhone screen.
The chest engine is very good and it plays like a human player more or less although I found it makes blunders maybe in the beginning but then it comes on strong at the end which is like a human player. On its lower levels like 1400 its very strong I pit it against Shredder and it beat a 1600 Level easily.
So I think its lower-level designations are not very accurate.
It has a hint feature which is rather slow it takes about two or three seconds for it to give you an answer which is a little bit slower than Shredder.
