You can adjust Shredder’s playing strength from beginner to master level. If you like, Shredder automatically adjusts his strength to yours. He even calculates an Elo rating for you. This is how the playing strength of chess players is typically measured.

During the game a coach is watching your moves and warns you if you are about to make a mistake.

My go-to Chess app

Nothing to complain about really. With decent play and puzzles this is a great offline chess app. If I could change one thing it would be to use standard algebraic notation.

My favourite IPhone Chess implementation (and I’ve tried most of them).

Love it

I'm loving this app. Very full-featured. I especially like the way it adapts to your level of play and rates you - mind you the rating system is pretty generous when you consider it lets you take back moves in rated games! Strength-wise, any half decent chess engine should kill pretty much anyone except a master-level player, so it's a moot point for 99% of players. What's more interesting is the way it degrades it's play. I'm not quite convinced by Shredder's deliberate mistakes - it plays a strong game then drops some suicidal clanger. But it still makes for a fun, challenging game of chess, and
having such a powerful analysis tool in one's pocket is terrific. Get it. The position setup feature gives it a big edge over Fritz, much as Fritz is king on the PC.
