CHESS EDUCATION FOR EVERYONE

Meet Masti. Chess coaching for everyone.

World-class chess coaching has been out of reach for most players. Masti changes that: Stockfish 17 calculates, Masti explains in plain words, and a validator checks every claim. The same caliber, free for everyone.

Stockfish says +1.8 — sharp but holding. The cleaner path was 14.Nd5 first; you'd be +2.4 with no defensive work. Want the full line?
