Сhess Tactics Trainer 500-2500

Hello. I’ve created a new project using AI and the Lichess puzzle database.
In this project, you need to solve puzzles to raise your rating. The faster you solve a puzzle, the more points you earn, while mistakes incur penalties.
The puzzles focus exclusively on winning material; checkmates are excluded.
Blunders are highlighted in green, and please note that moves for Black are displayed from top to bottom. This helps players learn to avoid blunders in actual games.
Let me know what rating you achieve.
Link in my bio.

This is the maximum complexity in a reduced task base.
Complex problems are truly complex. There is a check, there are 4 escapes from the check, but only one move is correct.

This project has a hidden feature for beginners.
If a player has a rapid rating of approximately 800, the player can solve several problems to get a rating of 800+- on the simulator.
Now you need to click on the number (it turns green), the project will fix the rating. In this mode, the student must train to think quickly. The rating will not increase or decrease. The player can solve 100 problems in a row to practice simple combinations.
These typical combinations will help you defeat equal opponents. After training, during the game, the eyes themselves will see the opponent’s blunders and which piece can be knocked down through check.

The secret button is located at the top left of the board.
If you solved a problem that you found interesting or incomprehensible, and you want to share it, click this secret button. The project will return to the previous task, which you can screenshot and forward to friends, a coach, or to the forum for analysis.

The secret button is located on the top right above the board.
If you look at a problem for a long time and cannot see the solution, click the button. It will restart the task and show an animation of the last move. This move is wrong. Sometimes animation helps the student see the motive behind a tactic. This button can also be useful when the player has made several moves, but wants to return to the beginning of the task.
Or if the player liked the task, he wants to take a screenshot and send it to his friends so that they can also solve this puzzle.
If you need to show the task to the coach, click this secret button, reset the task, show the screenshot to the coach.

What are the main differences from other online puzzles:

1. From a database of 6 million puzzles, I removed 2 million tasks for mats. There are 4 million puzzles left for combinations and tactics.
2. You can select the fixed difficulty. A player with a rating of 1700 can order tasks with a difficulty of 700. This is a strictly fixed value. Puzzles are selected from a range of +-20 points from the selected one.
3. Half of the puzzles start from top to bottom. The board does not turn over when Black moves. This helps train the student to notice counter threats and counter combinations. Teaches you to see mistakes and prevent them.

Include the mate puzzles

Puzzles on the mat are the most harmful puzzles in the world. A beginner solves thousands of puzzles on the mat, but yawns the simplest mistakes. Because he knows how to checkmate, but does not know how to make 40 moves leading to checkmate. If you want puzzles on the mat, you can choose in the themes on lihess M1 M2 M3 M4 M5+. I hate mates. Now everyone stop practicing puzzles on the mat! Stop from this second!
