on line vs live tourneys

Hoping not to sound like an idiot, I'm having trouble playing live tourneys yet do fairly well playing on line. Besides the number of bad players online (due to the overall number of players total) being higher than at a live game, could the speed of the game be a factor as well? (Removing my bad play from the equation)... Has anyone else had this problem? I prefer to shuffle chips in my hand instead of clicking the mouse all the time .... BTW, play a small home game tourney and do very well, but when I venture out to the cardrooms/casino I wont make it the the 2nd break before hitting the rail....
Thanks for your time and any responses that are given...

Live tournaments typically have HORRIBLE structures, with blind to stack ratios making them pretty much crap shoots. That could be part of the problem. However, I don't think it's the skill level of the competition: I have found live players to be MUCH worse than online players in general.

casinos are about making money! sure the structure will be at turbo pace, so be ready to get your chips in goo if involved in one. but the ring games. watch peoples feet for tells. for they will not be able to hold them still if they have something, and dead calm if they have nothing.
Don't forget to tip the dealer with every hand you win at these.

I think when you play at home and with friends people can be relaxed and having a good time. When you go out and play with different people, you need to be cautious and really watch how people play. Another thing is you can't be scared to throw your chips in the middle. Also decision making can be harder, so be carefull.

AG's pretty much nailed it - unless you're playing a big tournament, the structure is probably against you. The casino typically wants the tournament over within three or four hours so they can have the tables and dealers back for cash games, so they set the structure accordingly. That means you'll usually be starting pretty short stacked. Rake / entry fee is often artificially high too.

That said, they can still be good fun and you can still do well in them if you're a decent player. You'll probably find you need to play a little faster a little earlier than you normally would. Pay close attention to your M, be willing to gamble a little, and see how you go.
