Decision summary
Analyze a game to compare each side's decisions.
An engine’s view,
with room for nuance.
Move labels are estimates based on expected score lost against the engine’s top line. Brilliant looks for a sound piece sacrifice; Great looks for a clearly stronger only move. Search depth and device speed can change a result.
The position score is shown in pawns from White’s side. A single game cannot establish a player’s rating.
