About this game
Repetition is an essential aid when it comes to learning new skills.
It allows the conscious thinking to transfer to the subconscious, freeing up time for new and more complex reasoning.
It is difficult to have things go wrong when you always play the best moves as analysed by a strong chess engine.
The Chess Exerciser application aims at helping you play the best moves repetitively.
Decide how you and your virtual opponent are going to play while you are still in the opening repertoire, or when you are in the continuation line.
Receive hints when you make a mistake, so you can learn from it.
Each time a new line starts, the application will randomly choose a new variation, but you can also request to replay the last line again if you want.
The puzzles are extracted from a database of 3.000.000+ puzzles, and split into 38 categories and 11 difficulty levels.
Pass tests for unlocking the next difficulty levels.
Review your test results, identify and train your weaknesses.
The positions are all sorted by category and difficulty, and are all extracted from real games.
