No Limit Texas Hold'em tournaments. I love how the game changes as you go through the different phases of the tournament and then the thrill of making it to final table and the intensity if you are lucky to make it to heads up at the end. It is totally riveting. Nothing like it!
The Cadillac of poker, NLHE.
However, a good friend of mine said his favorite text I ever sent him read something like, "Just took down a $15 Badugi tourney on Stars! DRunkenly!!! My new favorite game!"
