China and Kazakhstan reached the rest day as joint leaders of the Women's Chess Olympiad, both on a perfect 12/12 match points after winning their sixth-round matches on Monday.
Third-seeded Kazakhstan edged Azerbaijan 2½–1½, while fourth-seeded China produced a much more convincing result against Poland, winning 3½–½. The two leaders are now set to meet directly in round seven.
Their position at the top also brings together the two highest-rated players in the women's event: Zhu Jiner for China and Bibisara Assaubayeva for Kazakhstan.
Kazakhstan's victory over Azerbaijan was settled by a single decisive game. Three boards ended drawn, leaving Alua Nurman's win over Gunay Mammadzada as the difference between the teams. The game appeared objectively equal in an endgame with rooks and same-coloured bishops, but Mammadzada made an unexpected mistake and Nurman took full advantage.
Mammadzada underestimated White's ability to gain activity by threatening to trap her dark-squared bishop and faltered with 28...Rd6?, when 28...Bb6 was necessary. Nurman found the refutation: 29.a4 c6 (creating a escape route for the bishop) 30.b4 Bb6 31.Rxc6
White has an extra pawn and her connected passers on the queenside are very strong. By move 39, Mammadzada realised there was no point in continuing the battle, as Nurman had already collected Black's a-pawn and her pawns had reached the fifth rank.
Nurman has now scored 4/5, corresponding to a tournament performance rating of 2482. Elnaz Kaliakhmet has been even more productive in terms of points, collecting 4½/5 with a 2471 performance rating.

China, meanwhile, had a much smoother afternoon against Poland, who had stunned India in round five. Song Yuxin, Lu Miaoyi and Yan Tianqi all scored wins as the fourth seeds completed a 3½–½ victory.
Playing black against Klaudia Kulon, 16-year-old Lu (currently ranked 12th among girls aged 20 or younger) showed her technical-endgame abilities, as she outplayed her Polish opponent from the following position.
Kulon's 30.a4 was not the most precise continuation in this rook-and-knight endgame. Soon Lu began to activate her king while dealing with White's threat of getting a passer on the queenside. With the rooks off the board, it became clear that the pure knight ending was superior for Black.
White is already in trouble here, but 37.Nc4?? only made matters worse, as after 37...Nxa4 38.Nd6 (White goes pawn hunting on the kingside) Nc3 39.Nxf7 Nd1 it is Black who will get to promote a pawn more quickly than her opponent.
With the more active king, Black is winning.
Zhu Jiner has registered the highest performance rating among the Chinese players so far, with 3½/4 and a 2720 TPR. Song Yuxin has scored 5½/6, good for a 2633 performance rating.

Behind the two leaders, eleven teams are tied on 10/12 match points.
Top seeds India bounced back from their round-five defeat against Poland by beating fifth-seeded United States 3–1. The decisive points came on the bottom two boards, where Vantika Agrawal and Savitha Shri scored victories.
Georgia are also part of the chasing group after a slow start to the event. The second seeds had already conceded two draws in Samarkand, in rounds two and four, but responded on Monday with a clear 3½–½ win over Uzbekistan.
The lowest-seeded teams among the 11 chasers are Switzerland, Armenia and Mongolia.
