Before the start of the tournament Irina Krush and Anna Zatonskih, who have been dominating the US Women's Championships for the last ten years, were considered to be the biggest favorites. But after four rounds it is Irina Krush who shares the lead with Tatev Abrahamyan and Nazi Paikidze - they all have 3.0/4. In round three Irina Krush, the defending champion, was lucky to escape with a draw against Alisa Melekhina but in round four she was back in form and won against Agata Bykovtsev.
Anna Zatonskih is half a point behind the three leaders and shares fourth and fifth place with Carissa Yip. After three draws Anna Zatonskih scored her first full point in round four by winning against Alisa Melekhina.
