What Lotus Chess Trainer is for

Lotus Chess Trainer is a chess training app with three parts: openings, tactics and endgames. The developer pitches it at a wide range of players, from people learning the basics to competitive players rated up to 2300 Elo.

Its stated approach is attacking chess aimed at winning against human opponents, as opposed to memorising engine-perfect theory. The listing says it has more than 250,000 learners.

Building openings from your own online games

The app analyses up to 3,000 of your online games and looks for the places where you tend to go wrong. From that it builds a personalised opening course.

The course is meant to strengthen the openings you actually play, so the lines you practise come from your own results rather than a generic list.

Opening lines chosen by win probability

The developer says its AI analysed more than 100 million games to find the lines that give the highest win probability against real players. These are the lines the course leans on.

The lines are described as crushing sequences that exploit common mistakes, rather than long theoretical variations that seldom appear in practical games.

Attacking play against human opponents

The listing presents the app as a way to learn attacking chess, meaning ideas for pressing an advantage and converting it into a win over the board.

Tactics and endgames sit alongside the openings in the same system, so the attacking ideas are meant to carry from the opening into the middlegame and the ending.
