One training cycle per day: 3 puzzles × 5 categories, then 2 endgames. Next Puzzle keeps you moving.
Fast tactical recognition and basic mating nets
Drill forks, pins, material wins, mates and back-rank tactics, then convert K+Q and K+R against lone king.
Goal: Build confidence with forcing patterns and clean conversion.
Each day follows one complete training cycle: solve 3 puzzles in each of 5 tactical categories, then play 2 endgame scenarios against an AI opponent. The interface auto-advances through every step - you just keep pressing Next and the course takes you from your first tactical puzzle all the way through to your second endgame without any extra navigation needed.
The course rotates through 10 tactical themes across the week: forks, pins and skewers, discovered attacks, deflections, sacrifices, trapped pieces, back-rank mates, checkmate patterns, defensive moves, and winning material. Each day uses a different mix of 5 themes so your brain encounters new pattern combinations every session.
The endgame tasks are sequenced to build skill progressively. Early days cover fundamental checkmates - King + Queen, King + Rook, two bishops - and pawn endings with opposition and key squares. Mid-week moves to practical rook endings and minor-piece races. Days 6 and 7 tackle the most demanding positions: queen vs rook, rook vs rook, and longer multi-pawn rook endings that require sustained technique from start to finish.
Most improvement programs focus entirely on one area and leave the other underdeveloped. But in real games, tactical sharpness helps you find winning moves in endgames, while endgame precision teaches you to stay accurate when converting advantages. Training both in the same session creates a feedback loop that makes each skill reinforce the other - so your overall game improves faster than drilling tactics alone or endgames alone.
