Perfection!!!! I have used many chess GUI's in my time  both professional and free one's. This is by far the best and most user frendley. Stockfish with a playing strength over 3000 elo  you can use to visually show it's thinking lines. It's like having a world champion train you. The GUI runs Komodo 8 perfectly. Brilliantly supported app. I now use this app almost exslusivly. Download it and enjoy!!!!
