It was a volatile day at the top of the standings as GM Irina Krush first lost the lead before regaining it during a dramatic third day at the 2020 U.S. Women’s Championship. Things were looking good for the recent U.S. Girls’ Junior Champion, WGM Carissa Yip, who grabbed the lead after winning her first two games of the day, but a critical Round 9 loss to WIM Ashritha Eswaran left Carissa in a tie for second with IM Dorsa Derakhshani.

Round 9

The final round of the day saw a complete turnaround as WGM Carissa Yip misplayed her position and ended up losing to WIM Ashritha Eswaran, despite a hail-mary attempt in the late middlegame:

 
Yip vs. Eswaran

Carissa tried to turn the tables with 28.Rxg7+!?, but Eswaran was able to defend after 28...Kxg7 29.Bh6+ Kxh6 30.Rxe4 Qxh3!

Yip’s loss opened the door for Krush to overtake the lead, which she managed to do thanks to a fantastic attacking game against WGM Tatev Abrahamyan, where the 7-time champion sacrificed a full rook to checkmate Black’s king:

 
Krush vs. Abrahamyan

GM Krush bounced back with a nice demonstration of the power of two bishops.

In the meantime IM Dorsa Derakhshani won her game against IM Annie Wang, continuing the 12th seed’s remarkable run in this year’s championships to tie for second with just two rounds left to go.

 
Wang vs. Derakhshani
Position after 13...e5

IM Dorsa Derakhshani won her 4th game of the event to stay within half a point of first place.
