Just ....bloody good. Better even! A core classic must have app for chess nuts  if you could pick only two android chess apps this would be one  maybe DROIDFISH would be the other or Chess for Android  or maybe the """"""""""""""""CVNCS"""""""""""""""" Chess app with it's twenty thousand (or 34 000 or whatever it is) puzzles for free  but if you had to pick just ONE  it must be this one  you could put a huge db file of puzzles  mate in 1 or 2 or 3  or tactics and use the Study mode to see if you can guess them. Install Stockfish to analyse..brilliant.""
