1. threatened squares: Displays the status of each piece on the board. A red square means that the piece is under attack and not sufficiently defended, or that it is being attacked by a piece of lesser value. This is usually a pretty serious danger signal and means you must take active measures to avoid losing a piece. Yellow means that the piece is under attack, but it is just sufficiently defended. You must be careful about removing any defending piece. Green means the piece has enemy contact but is well defended. Usually it is okay to remove a defending piece.

After update of Android 6.0.1 on my Samsung A6 tablet the board no longer fits the screen (only 6x8 fields) no matter what I do! Great before - now useless. Please fix asop.

So many illegal moves. Not too big on it. Fix it please.
