Why train chess visualization
Visualization is the skill behind every deep calculation. Players who see the board clearly blunder less, spot tactics earlier and read endgames faster. Blindfold training builds working memory, concentration and pattern recognition, and all of it translates directly into better results over the board.

It also works the other way around. If you already play well but lose the thread three moves deep, blindfold drills are the fastest way to find out exactly where your inner board breaks down, and to repair it.
