In round 6 Gull, Gaviota, Protector, and Hannibal all scored full points. Critter secured a good position after a draw with Stockfish (a 3000+ ELO game, replay here), the same result that appeared in the 191 moves game between Arasan and Chiron (the longest game so far, replay here) and Spike against Octochess.
In one of the most expected games of round 7 Stockfish drew with black against Chiron in a Neo-King’s Indian Fianchetto System. After a bizarre opening, the engines reached full equality and shuffled pieces for a few moves before reaching the draw (replay here). Gaviota showed again teeth and defeated the previous rounds surprise Cheng4 in a King’s Indian with 4.Bg5 (replay here).
