Exercises
Train the tactical and checkmate patterns — drawn from your own games and a verified puzzle library, picked at your level.
Opening
The opening has no bank of its own: you train it on your real games. Master the fundamentals, revise your repertoire and fix your mistakes as you play.
Attack
Offensive Rush60 seconds on the clock: find as many winning tactical moves from your games as you can. Score out of 100.ForksOne piece attacks two targets at once: the opponent can only save one. Learn to spot the fork, sorted by the piece that delivers it.PinA line piece freezes an enemy piece: moving it would expose a more valuable piece (or the king) behind. Learn to spot and exploit the pin.SkewerThe reverse of a pin: you attack the more valuable piece first (often the king), which must step aside and drops the piece behind it.Discovered attackA piece steps aside and uncovers the attack of a line piece behind it: two threats in one move (and a discovered check is brutal).BatteryTwo long-range pieces lined up on the same file or diagonal multiply the pressure: the battery. Learn to build it at the right moment, against the right target.Remove the defenderA piece is only defended while its defender holds: capture, chase or deflect the guard, and the target falls.CCT scanChecks, Captures, Threats: before every move, list all the forcing moves. Train that reflex on your own positions.CalculationCalculate the forced sequence all the way through before you move.BlindfoldMemorise the position, then solve with the board hidden: train your visualisation.

Defense
