Poker can sometimes be really frustrating. The last two times I have flopped a two pair: 1) My opponent had a 3 of a kind, 2) My opponent had top two pair, while I had the top pair and the third pair. I lost a lot of money on both occasions. Maybe I’m playing those hands too fast and loose, and not paying enough attention to my opponent. But I suppose luck has a bit to do with it too.
