Calculation trainer · Engine-backed feedback · All ratings
Calculation is the single most undertrained skill at every level below master. Most players know the rules of opening theory and the names of the tactics, but they lose games because they fail to calculate accurately three moves ahead. Find the Best Move is a focused trainer for exactly this skill.
Each position is taken from real play. Find the strongest continuation, submit your move, and the engine confirms whether you found it — and if not, explains the move you missed. Over time, your eye sharpens for the kinds of resources that decide games: zwischenzugs, quiet defensive moves, sacrifices that look impossible until you see them.
