Blunder Override

Find the mistakes hiding in your opening prep

A focused pass over your recent games that finds the positions where you left your prepared opening lines behind - the blunders that a little extra drilling would have prevented.

One pass, every time

Blunder Override is not a full game review. It is a targeted sweep that flags the single worst deviation from your known openings in each of your recent games - the move that cost you the most ground in a position you thought you were ready for.

It is built for speed and honesty: one summary, one priority, one line to send back to the trainer. It exists for the gap between knowing a line and playing it under pressure.

The moves that need another five minutes

Most of the moves in a game you played well are not worth drilling. Blunder Override isolates the ones where you had the position prepared and still went wrong, and sends exactly those positions to Practice mode.

  • Free: two Blunder Override sweeps per day.
  • Plus and Unlimited: higher daily limits.
  • Each result links straight into the trainer for immediate drilling.

FAQs about blunder override

How is this different from Game Review?

Game Review shows you the whole board after the game. Blunder Override asks one narrower question: in positions you had prepared, where did you stop knowing what to play? It is the same data, a sharper focus.

What data does it need?

Your recent games and your current repertoire. It matches every move against the lines you have trained, and reports the worst deviation that happened inside your own preparation.
