Real-time feedback in the position vs retrospective dashboards

Aggregate percentages (“You score 43% against the French”) tell you where results leaked last month, which helps if you already play high-volume online blitz. They are less helpful when you want to sit down on an iPad for twenty minutes without opening a browser or feeding an online blitz habit first.

Brass Pawn closes the loop inside the session itself: play a coached game at your target strength, see immediately which move dropped win probability and which board feature changed, or work through missed tactical motifs that automatically return on your local spaced-repetition schedule.

No external account required

If you take a break from online rating pools — or prefer playing friends over Game Center and over the board — Aimchess has no new games to ingest. Brass Pawn’s bundled 14,351 tactics, 116 positional positions, 15 endgame drills and 900 Watch games remain ready offline at any time.

  • Aimchess runs in any desktop browser and on Android; Brass Pawn is native to iPhone, iPad and Mac.
