Actually I do not quite agree with you on that ... In MTT's it is really a problem that Harrington hasn't covered the semideep stack (yellow) zone ... Trouble is that you have to survive for a long time in a MMT and since so many are playing and therefore busting out, the others stacks tend to grow very large compared to you, If you just let you self drift into the red zone

But SNG are quite another beast since you are only ten to start with, you are still quite large compaired to the others when getting shortstacked, apart from one or two who have doubled or tripled, everyone is hitting the shortstaked zones at the same time, so you just push .... good thing is since everybody else is also about your size, you must be respected.
