There was a time that poker was a man's game. Of course that's not true anymore-poker has very much become a co-ed game. There are many women poker players today, and they're welcome every place I've ever played. Still, the majority of poker players are men, and men are still men. This works to the advantage of women who understand it and can exploit it. If you're a man, you should be aware of this and take defensive measures.
The majority of successful women poker players are more aggressive than their male counterparts. All successful poker players are aggressive players, but successful women tend to be almost hyperaggressive. They seem to have found success in adapting this style because it usually works well against almost any male poker player. Aggression tends to work well for women because of the way most men perceive and react to hyperaggressive women. You can categorize men poker players according to the way they to react to women at the table.
