Connecticut Chess Magazine: CONNECTICUT HAS 36 TOURNAMENT DIRECTORS

Pitted against the machine programmed by humans, the machine’s machine now has a two game lead in the TCEC 14 Superfinal. There was a long series of draws from game 30 to 48 where it seems the neural network took the measure of its opponent.
Just like there were some interesting draws in the Carlsen-Caruana classical match, the programs gave us this 135-move game(the last fifty moves were omitted here because the machines just dance around an obviously drawn position). Each side is after the other’s king with a queen-led attack. It appears that Leela will have at least a perpetual check while the best Stockfish can hope for is a perpetual on the other side of the board. Both sides must calculate queen checks and king moves and pawn promotions. Incredibly, before either attack even develops, Stockfish has apparently seen the whole thing and on move 33 evaluates the position as equal, an opinion it maintains all the way to the finish.

When Stockfish first went to +0.12 on move thirty, it seems likely that it had actually calcuated fifty moves ahead in these variations.

Roman Rychkov of New Jersey and Benjamin Amar of Maine, both students at UConn, tie for first at the Hartmayer Memorial.
