TCEC Season 8,
directed and organized by Anton Mihailov, CEO of Chessdom Arena [2], started on August 21, 2015. There are 3 Stages plus the Superfinal. Stage 1, a single-round robin consisting of two seeded sub-divisions of 12 engines each, is played without book openings. In Stage 2 the top six surviving engines from each of the two divisions in Stage 1 compete in double round-robin, using a two-move book designed by Adam Hair and checked by Nelson Hernandez (alias Cato the Younger) for statistical and evaluative play-balance. Stage 3 and the Superfinal used an opening book of 8 moves. Komodo 9.3x won the Superfinal versus Stockfish 021115 with 53½-46½.

Due to the severe problems with crashes, three engines will not be allowed in further stages. Junior, Pedone, and Equinox will not move on even if top 6, as the frequent crashes create both extra work for Martin Thoresen and discontent in the audience [4] .
