### 5/5 — Great app

Tactical puzzles are amazing

### 5/5 — The best

*2025-07-16, version 1.2*

If you are looking to improve this is highly recommended. Many chess puzzles only show one variation. You find the move and the opponent falls for the trick even when it isn’t forced. This course shows you that you need to be able to calculate all the responses from your opponent. The tactics are themed and eventually after repeating the lessons you will inevitably improve your calculation skills and exploit opportunities in your own games. If you compare this to the price of a chess book it is amazing value for money.
