I remember few hands, for both good and bad reasons.
Recently I was in a pot with a very aggressive player, flopped a royal flush, and mis-click folded to his opening bet. I won't forget that one anytime soon.
I remember flopping quad queens in a four way pot, and getting two of the three to put in all their chips. That was awesome. Nearly quadrupled up.
I remember a very long time ago, I flopped middle pair on a wet board and called a guy's
bluff down when he bet pretty large trying to represent a straight when he had a busted flush draw. I've been involved in similar hands plenty of times since, but the reason I remember this one is that the guy went insane berating me for calling him down. I probably in hindsight wouldn't do it now, but at the time I had a "feeling" he was
bluffing, and I went with it. The vehemence of the guy has always stuck with me.
