Play the fastest flawless chess you can against a 2000-rated bot. One slip — or one flag — ends your run.
Every move must be one of the engine’s top three. Sacrifices are re-checked deeper, so genuinely strong moves always pass — the first move that isn’t ends your run.
You play on a chess clock. If it hits zero your run ends right there — a flag is as final as a blunder. Every clean move banks the increment.
Most clean moves tops the board; tie, and the faster player wins. Two modes: Rapid (15+5) for precision, Blitz (3+2) where every second counts.
