Traditional Chess Study is Broken.

You watch a 15-minute opening guide on YouTube. You skip through the lines you already know. You get overwhelmed by variations you'll never see in your actual games. By the time the video hits the exact square where you always misplace your bishop, you've already zoned out.

Wasting time on generic courses won't fix your opening repertoire. If you want to stop losing games before move 10, you need to know exactly where your games are falling apart.


Built Out of Pure Frustration.

Personalized Opening Videos were born when our founder, a 1370-rated player, watched GM Daniel Naroditsky break down the strategic ideas behind the Jobava London. One concrete plan stood out: capturing a knight on the edge to force doubled pawns and seize square control.

Shortly after, he got paired against a 2200-rated opponent. Instead of getting crushed, he walked out of the opening with a serious advantage: a position Stockfish rated at over +3 in his favor. He eventually lost the endgame, but that wasn't the point. The opening worked.

A few days later, the same plan against a 2000-rated opponent. Another win.

The lesson: you don't need a GM's endgame technique to gain real rating points. If you consistently walk out of the opening with an advantage, you get the confidence, the safety cushion, and the psychological edge to win more games. But manually digging through your own game history to find every hidden opening leak is a nightmare. So we automated it.


How Blackbox Chess Builds Your Custom Opening Plan

1. The Free 10-Game Scan

Plug in your Chess.com or Lichess username, or upload a PGN. With a click of a button we scan your recent games to pinpoint the exact moments your opening choices cost you.

2. Tailored to Who You Actually Play

We don't train you to play against Magnus Carlsen. We look at what players at your rating level actually throw at you, so you learn to beat the moves you genuinely face over the board.

3. A Personalized Video, Delivered to Your Inbox

For each opening where you consistently leave theory, we build a short narrated video, 2 to 3 minutes, covering what you played, what the engine recommends, and exactly why it matters. Generated from your games and emailed directly to you.


The "Aha!" Moment

"Wow this is great, this is something I actually struggle with. That is part of the Gotham Chess lines but sometimes he recaptures with the pawn and sometimes with the bishop. I never understand why it's either or. But from your video it seems as though the determination is if the opponent's c-pawn is advanced. I will have to review all those lines and see if that holds true. Definitely an aha moment!!!"
