Ok well heres a question for cotta.. You say when you play MTT you take more risks and such to get big stack to play for first..
... Should my game really change THAT much when I go from cash to MTT?
I can give an idea of what I think he means, based off of what I've seen / think from the OL MTTs I play.
When the blinds are low -- from 10/20 to 40/80, lets say, you have the opportunity to play more pots, cheaper -- especially in DS tourneys.
This can be a great time to play smart LAG, and increase your stack size. Doing this successfully, you'll be well over 20BB by the time blinds are 50/100 -- the point in the tourney where short stacks have to start shoving.
But the LAG strategy is always chancey -- especially early in the tourney when you don't have a great read on your villians. Your bluffs may get called and beat by poor hands from lucky players.
This might not be what Cooto was saying exactly, but this is how I interpreted it. Early in the tourney, when your average player is probably playing tight, you can play loose, and attempt to position yourself stronger for later in the tourney. Considering this is a gamble early on, you're either going to gain a big advantage, or you're going to bust out pretty early.
It's up to you how you want to play it, but this is one approach that I think is exclusive to MTT.
