First of all...

Really? Heh heheh. Hehe.
Here's my take. And it's not even about win-rates or.. well it is... but it more result oriented than that. Cuz i roll all results oriented in my game. Woo Hoo! ( I might be slightly drunk)...
Back to the point.
The main reason I like to keep a big stack at the table (aside from I prefer deep play to shallow or even 100bb play cause I am loose and stupid WOO ... wait off track again...)
There is ONE THING worse than getting your stack in the middle when you are are 92/8 just to see your enemy hit his 2 outer on the river.
The only thing worse is:
Getting
NEARLY all your stack in the middle when you are are 92/8 just to see your enemy hit his 2 outer on the river. And
THEN being dealt
AA when you are sitting there still stunned and realizing you are now holding the nuts and have a whopping 4BB behind.
Play enough poker without making sure you have a full stack... and I guarantee it will happen.
