Very nice for users trying to improve their games I have played chess since the day I was (like the rest of the world) captivated by Bobby Fischer's run to World Championship versus Boris Spasky and the (then) hated Russians. For all the intervening years  the best I can muster is a (maybe) 1200 ELO. The only way to improve for me is to study the game  learn the nuances and most importantly study and play games. This app is an excellent and free start into this type of study and my heartfelt thanks to the developers for giving me this chance to improve!
