Get a sample size before you change an opening
Four games in a new line will look like a leak or a weapon. Neither is true yet. Chessigma stays quiet until the fork repeats; you should too.
Change a repertoire when the same position keeps scoring worse than your usual move across a real sample. A weekend of experiments is noise.
The report already has a floor
Chessigma needs enough games to say a pattern is yours. If the DNA card is blank, that is the product, not a bug. Play the line you already trust until the sample exists.
A new opening you tried because a streamer did is not a repertoire. It is a vacation.
Swap the move, not the whole tree
If a fork on move twelve is the leak, drill that FEN. Buying a 20-hour Najdorf file because the Italian had a bad month is how club players stay busy and stay the same.
Frequently asked questions
How many games is enough?
Enough that the same board comes back. A single loss is a game. A habit needs repeats.
Should I stop playing the line while I wait?
No. Waiting without games is how the sample never arrives.
