960 possible starting positions. Your moves decide which survive.
Quantum Chess960 begins with the back-rank pieces unresolved. Squares hold every possible piece within them, and each move eliminates states where that move was impossible.
Move a piece like a knight, and only the possibilities where it was a knight survive. But your opponent can narrow the possibilities too. A strong position must survive both their threats and their choices. Familiar chess tactics take on new meanings. A move can have different consequences across the remaining boards, and a seemingly trapped king may escape because it was never there at all.
