Material, structure, and king safety at a glance
Before you spend minutes on engine depth, get a fast positional snapshot. Chessyi computes material balance, center control, piece mobility, pawn structure features, king safety, development, and game phase for any position.
It is the perfect first pass when reviewing your games: spot hanging pawns, lagging development, or an exposed king before diving into Stockfish lines.

What you get
- Instant metrics without waiting for engine depth
- Material count and imbalance display
- Center control and mobility scores
- Pawn structure highlights (isolated, doubled, passed)
- Game phase detection (opening, middlegame, endgame)
