e4coach — your personal chess coach

e4coach — your personal chess coach이란?

Every chess player analyzes games to find single blunders, only to repeat them later. Game-by-game review is useful, but it can’t reveal the one thing that actually raises your rating: your recurring errors. You’re left trying to spot these patterns across dozens of games from memory, which almost nobody does. That’s the gap I built e4coach to fill—automatically finding the mistakes you make over and over.
