A summary of Gigabet's stack size thread

[DonT77]

The chips in the pot will be attracted to players in proportion to their stack sizes. (caveat - if they know how to use their stack.)

Thus taking on slightly -EV plays in hopes of building a bigger stack makes sense if you think of the "implied EV" behind the situation.

Spelling it out - if you are getting 2:1 on a call, but you estimate that you need 2.2:1 for the call to be 'correct' based on pot odds, you might consider the added benefits that winning that pot might give you later on if losing on that call doesn't change your chip position much.
