Premier Division will consist of six double round-robins. The first of these six round-robins (56 games in total) will be bookless. The subsequent five double round-robins (280 games in total, 140 openings) have been selected by Nelson (Cato) and be eight moves in length. All book-exit positions will have occurred no less than 500 times in the Catobase and meet other criteria for play balance, draw tendency, material on board and multiple first-move choices.

"No opening books at all, the other matches start at a position opening position but the engines never have access to a book"
OdgovoriIzbrišiSto znaci da i u drugoj seriji nemaju pristup knjizi otvaranja, vec startuju od tabija u 8. potezu

OdgovoriIzbrišipostoje dva mala prozora sa Glavnim varijantama tekuceg poteza.
Evo tumacenja tih analiza:
"Principal Variation - This shows the move sequence up until the end position the engine has calculated for the current move. The @ symbol shows where the white/black PVs diverge from one another. Note that the deeper the PV is, the less accurate it may"
Ovaj tip turnira je vrlo zanimljiv osobito nama dopisnim sahistima koji koristimo engine
OdgovoriIzbrišiu analizi poteza/pozicija. Interesantno je promatrati tok partije koja se igra sa punim
turnirskim vremenom (90' + 10") bez ikakve ljudske intervencije (npr. autora ovih programa,
ali koji npr. mogu komentirati u chat-u). Takodjer je od interesa pravilo TCEC za prekid partije.
Naime:
"It will adjudicate as won for one side if both playing engines have an eval of at least 6.50 pawns (or -6.50 in case of a black win) for 4 consecutive moves, or 8 plies - this rule is in effect as soon as the game starts. In the website this rule is shown as "TCEC win rule" with a number indicating how many plies there are left until it kicks in. Cutechess will also adjudicate 5-men or less tablebase endgame positions automatically."
Tako je npr. Komodo pobijedio Ginkgo u 64.potezu sa ovim TCEC pravilom za pobjedu,
kada je u konsekutivnim potezima evaluacija oba engina bila preko 6,50 do zavrsnih Ginkgo: 11.89
Komodo: 17.55
