The 16th season of the Top Chess Engine Championship began on 15 July 2019 and ended on 13 Oct 2019.
The season showed how fast neural network-based engines were progressing relative to traditional ones, with neural network-based engines making up half of Premier Division for the first time. Furthermore, AllieStein, a neural network-based engine that had reached Premier Division last season, made its first appearance in the superfinal after finishing second in Premier Division. Nonetheless, a traditional engine – Stockfish – won both Premier Division and the superfinal.
