There have been many serious women players for decades - the likes of Jennifer Harman and Maria Ho to Kristin Bicknell and Maria Lampropulos. They have proven they can play against any field at any stakes and win.
However, poker has had a long standing inherent problem, that of attracting more balanced fields with a greater number of women.
Its strange - so many within the industry talk of growing the game to create a healthier future for poker, yet half the population remain alienated. Much as I love poker, the industry generally has an insular view stuck somewhere in the 1950's
