Blindfold trainer

Playing strength, as is well known, depends largely on calculation technique, and that in turn depends on how well a draughts player can see the position in their head, without moving the pieces on the board.
Unfortunately, I have never come across any training aid for Russian draughts that could help practise this quality. So my son, the mathematician and programmer Viktor Naumik, and I created a simple trainer program, which we now offer for discussion.
The positions run from simple to complex. There are beautiful combinations and beautiful studies.
The idea is straightforward: the player has to complete the task by picturing on an empty board a position made up of white and black pieces, and then compare their own solution with the correct answer. You can try solving 100 tasks below.
Use the «up» and «down» arrows to move between positions

I realised long ago that simply training combinational vision is not enough. Training tactics develops a feel for tactics, and that is true. But unfortunately it does not protect you from elementary oversights in all sorts of positions. The reason is that during a game we can barely picture a position clearly even three moves ahead. And picturing it is not enough either — in that imagined position you still have to find the right direction to search in. That is where the real difficulty lies. In other words, you have to reach the point where you see a position in your mind as clearly as the one in front of your eyes. That is exactly what the blindfold position trainer is for.
If you start working with this trainer you can raise your playing level very quickly.
