This is a great app. It is functionally simple yet capable and looks great. The Shredder chess engine’s creator is a well known chess engine and also the co-creator of the UCI chess interface, universally used for interfacing chess engines and GUIs. The cost of premium membership is reasonable, which allows you to download your games using their web interface. The web interface allows you to play from any browser and looks pretty much the same as this app and is functionally otherwise identical to this app. What is missing is an analysis link between games completed here and the other Shredder app by the same author.

This is a superbly well thought out app but it has developed a couple of problems: 1) A few months ago latency increased considerably. I'm guessing the servers were moved to some new location, far away from the US west coast.2) After I updated my iPad to iOS 10 the app has become unusable due to a 1-2 seconds latency after many moves. Annoying in a 5 mins game, impossible in 1-3 min games.PLEASE fix these problems so that this will again be the best online chess game on the planet.

I must say that this is a truly great chess app for competitive and casual play. That in addition to great Shredder AI make this a great app. I do have a premium membership, which I will no longer continue. I’m not into blitz/bullet wars or restricted time limitations. I throughly enjoy correspondence chess and am having difficulty finding other players, who will accept challenges. Sure, I’m no reincarnation of Fischer but I don’t want to pay to wait around for a game. I hate having games aborted. It’s way too frequent.

Where to start... Okay, you get time controls, a great community of players, lots of options, it's FREE, the server network seems to never stall, lag, or crash... I wish people would play more here and less on that wonderfully popular, yet most basic of basic chess apps, Chess With Friends (which I play all the time). This is a vastly superior app.
