Following yet more successful norm-seeking, she became the third British woman to be awarded the IM title in 2005. Voted
English Chess Federation Player of the Year in 2006, she was the first female to receive the accolade since its inception in 1984. There were 'highest placed Woman' prizes at the
Hastings International Chess Congress 2006–7 and at
Gibraltar 2007. She also came close to winning the first
MonRoi Women's Grand Prix, finally finishing second equal behind
Pia Cramling. Her task was much more difficult at the fifth
Howard Staunton Memorial Tournament, held at
Simpsons-in-the-Strand, where she faced some of the world's top grandmasters and finished in last place. At
Liverpool in 2008, she became British and English Women's Champion for the first time, finishing a full point ahead of closest rival
Susan Lalic and a half point ahead of grandmasters
Glenn Flear and
Stewart Haslinger. Her second Liverpool visit resulted in a third share of the women's best performance prize (jointly with
Ketevan Arakhamia-Grant and
Yelena Dembo) at the
EU Individual Open Chess Championship. Houska successfully defended her British Championship title at the 2009, 2010, 2011 and 2012 events. By July 2010, her sustained good form had elevated her to an
Elo rating of 2433, making her England's second ranked woman player (behind
Harriet Hunt) and number fifty-one in the world among active female players. Further British Championship victories were achieved in 2016, 2017, 2018 and 2019. As a chess writer, she has reported on tournaments home and abroad for periodicals such as
CHESS magazine. Houska completed her first
chess opening book in 2007. Written for
Everyman Chess, it features a treatise on Houska's opening of choice with the Black pieces—the
Caro–Kann Defence. A second book, covering the
Scandinavian Defence, was published in 2009 and there followed a collaboration on 2010s
Dangerous Weapons: The Caro-Kann, with fellow English masters
John Emms and
Richard Palliser. ==Personal life==
