Dual Life Chess

Field notes

Dual Life Chess changes the basic exchange economy by leaving a first-hit piece wounded on the board instead of removing it. The homepage describes a king that can survive one fatal attack and an engine that searches nine plies with alpha-beta pruning, quiescence search, a transposition table, and square evaluation. Visitors can enter a human lobby, play the engine, watch engine-versus-engine games, or inspect an ongoing match move by move.
