Learn Chess Intently — An advanced tactical sandbox paired with a patient cognitive coach.
PINAKA pairs the precision of neural-network chess engines with cognitive visualization drills. Move from mechanical calculation towards genuine sight of the board. Features zero advertisements, zero tracking telemetry, and 100% free curriculum progression.
A built-in chess coach running entirely on your local machine. GM Chanakya reads your board in real time, names the cognitive pattern behind tactical slips, and counter-steers into diagnosed weaknesses with targeted drills.
Tracks where your tactical vision fails using delta coordinate analysis across eight cognitive channels: diagonal retreats, horizontal drifts, knight flanks, time panic, material greed, tunnel vision, pinned pieces, and abandoned kings.
Choose between the pressure-tested Rated Ladder (affecting your calibrated ELO rating) or the pressure-free Studio board with full evaluation bars, move undo, and position editing.
Roster of calibrated personas spanning beginner to grandmaster levels, each with unique temperament, style heuristics, contempt, and blunder profiles.
Piece movement, castling, en passant, promotion, piece values, trading math, and essential checkmate patterns corrected live by GM Chanakya.
Forks, pins, skewers, double attacks, center control, piece development, king safety, and honest 2-to-3 move tactical calculation.
Pawn structures, outposts, minor piece endgames, rook files, long-term prophylactic defense, and positional profiling.
