Koivisto - homepage
Koivisto is a chess engine first released in 2020 by Kim Kahre and Finn Eggers. Both wrote a chess engine before and decided to join forces. Koivisto is capable of playing chess, either vs. itself, other engines or humans. In itself, Koivisto is not a complete chess program, but rather makes use of the UCI protocol. The UCI protocol is the most common protocol for chess engines and is supported by all major chess GUI's which are required for a visual interface for the engine. Koivisto employs a sophisticated search based on principal variation search, which is in turn a significantly improved version of minimax. Koivisto takes this approach and adds various different strategies that help identify variations that aren't worth looking at or look deeper into promising variations. Combined with an efficient neural network which has been trained on billions of positions, the engine has proven itself to be competitive at the highest levels of computer chess.
