Insights64 launch: search 90 million chess games by structure

If you've ever opened a chess opening explorer and typed in a position only to be told "0 games match," you've hit the same wall every chess player has: exact-FEN search asks the wrong question.

You don't usually want the exact position. You want the structural shape — the knight outpost on the 5th rank, the isolated queen's pawn, the rook on an open file — across every variation, every game, regardless of where on the board it appears.

That's what Insights64 does.

What's in the launch

• Five filter types plus sort orders, all freely composable: piece placements, piece counts, sliding patterns, empty squares, and metadata (ELO, result, time control, move number) — combined with sort orders that pick what surfaces first.
• Move explorer: from any position, see the top continuations ranked by frequency, with the win/draw/loss split per move.
• Game viewer: every match is a real game — names, ELOs, full move history. Step through ply by ply.
• 90 million games indexed, every position searchable, queries in under a second on the typical shape.

What I'm working on next

A few highlights from what's on the way:

• FEN lookup — search by an exact FEN string when you have a specific position from a game or book in hand.
• Combining multiple patterns in one query — search for "this pattern OR that one" without stacking separate searches.
• A power-user text mode — type a query as a single line of text, share it via URL.

The full list — what's shipping next, what we're considering, and what's already landed — lives at /roadmap. If something's missing for you, there's a feature request form at the bottom of that page that goes straight to me.
