Using this reference
For Center Game, start at the first position and step through the moves rather than memorizing the final board. After each move, look for the piece that moved and the squares it now influences. The same opening name can cover several branches, so use the selected line’s move order as your reference.
The final position in the viewer is where this recorded line ends, not a verdict on the position. Choose another listed branch to see where the paths separate. The viewer displays legal source moves; it does not provide an engine evaluation or establish a forced continuation.
Opening lines
An ECO code groups opening lines, not one forced position. Step through legal notation from the CC0 Lichess dataset. This is a study viewer, without engine evaluation or a claim that a line is best.
The board shows one representative line for each ECO code. All collected branches and their PGN moves remain listed below.
