Spanish Game C67
1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6. It’s not exaggerated to say that one of the decisive factors of the final result of the match was the difference of understanding of the Berlin endgame.
4. 0-0 Nxe4 5. d4 Nd6 6. Bxc6 dxc6 7. dxe5 Nf5 8. Qxd8+ Kxd8 9. Nc3 Ke8 10. h3 h5. If nothing else, 10. ... h6 brought Black better luck in the third game, though only after a long struggle: 11.

Despite any appearance to the contrary, 侯逸凡 (Hóu Yìfán)’s two-point win in her semifinal match with 雷挺婕 (Léi Tǐngjié) was not an easy run through to tomorrow’s final against Dronavalli Harika. Screenshot from the live stream. |
"I guess it was a tough match for both of the players as most of the time the score was a tie or close to a tie," Hou then told Chess.com. "In general, I felt like the quality of this bullet match somehow was better than my previous match. But the score was very close."
