Endgame Training Includes • 60+ detailed lessons • Fundamental checkmates (queen, rook, etc.) • Advanced techniques like building the bridge • 180+ training positions to practice against a human-like engine Instead of only studying theory, you get to play and convert winning positions to reinforce what you’ve learned. --- Additional Features • All Endgame and Opening Lessons work offline (Great for the airplane and your commute) • 100,000+ chess puzzles • In-depth analysis of your online games • Personalized training recommendations --- Built by Chess Players Lotus Chess was created by two brothers who started playing chess at age four. After building a math learning app with over 6 million downloads, they set out to create the ultimate chess learning platform. The result is Lotus Chess: a modern chess training system that combines opening preparation, endgame mastery, and personalized analysis — which is now being used by over 250.000 learners across the world.
