Senior Chess 2.19

Senior Chess is a simple but strong chess program. No ads will be shown. Senior Chess supports both landscape and portrait orientations.

Anyone familiar with the rules of chess can adjust the play level arbitrarily so that both the human player and the Android device have a fair chance to win. This is realized by setting a suitable relative frequency (0 - 100%) of \odd moves\ that the app will produce instead of normal, strong moves. This feature makes Senior Chess especially interesting if you play at a moderate level and don\t want to lose every game. Even if you are an absolute beginner, you can win: just let 100% of all moves be weak ones, as demonstrated in http://youtu.be/bw408-vBQxw. Besides the promo video above, there is also a video that shows a game of Senior Chess, playing White, against a very popular Android app, playing Black. The strength of the latter was set at its maximum level, which is about 20 s per move. Senior Chess was also given 20 s for each move in this game: http://www.youtube.com/watch?v=VZkAmr9a8qI

After opening a game from a file, an animation of the game is played, as demonstrated here:
