Well in a low-stakes cash game, limping on the button probably is pretty much every time a bad play. If you're playing with world-class players on the other hand, you just have to mix up everything you do. Watch Sammy Farha play. I'm not a big fan of him but he will make moves that would never work against the type of players I'd play against online, but using his strategy he is able to hold his own with the best players in the world. I don't know what type of players he's talking about. Tyler Caby, an extremely good poker player said joining a poker forum
was the best advice he could give. Granted he is an online player.
But the main point about for example this site, is our goal is not to be able to sit down and play with Phil Ivey, Daniel Negreanu, Doyle Brunson, etc. and win. Most people here have a goal to beat low to mid stakes tourneys and cash games online. It would be like major league baseball players showing up at a U14 baseball practice and laughing at them. Now don't get me wrong we have several extremely excellent players at this forum, but I don't think any of them could for example sit down at high stakes poker and even break even, they'd get destroyed. But we do have people making money, in some cases a lot of it, from the games they're good at. Most people wouldn't mind being world-class poker players, but most people realize that is a long-shot.
