A Squares Assistant scouting report: the opponent's worst-scoring openings, the position on the board with Stockfish's evaluation, and recommended lines to play.
A scouting report in Squares Assistant, shown with sample data.

Strategic superiority

Everything you need to take an opponent apart before the first move.

Opponent scouting

Point it at a player's games and get their recurring opening mistakes ranked by how often they play them and how much they cost — plus the openings they score worst in.

Live evaluation

Stockfish deepens continuously as you move, streaming the evaluation straight to the board. Push to depth 30 when a line deserves it.

Your own database

Import PGNs from anywhere. Games accumulate on disk, duplicates are removed automatically, and your games never leave your computer.
