This was very interesting, and had some good points.
For beginners the guide :
Big Stack Envy 20-30BB Tighten up, play big hands and position, eliminate set mining with small pairs (<77), stop
bluffing, forget about defending your big blind.
Vertically Challenged 10-20BB Only play monsters, be willing to go all-in on a pre-flop re-raise, increase pre-flop bet sizing, no limping or blind stealing, stop set mining with middle or small pocket pairs (<JJ).
Small stack complex <10BB Shove first playable hand.
This is great advice for them - however, once you get too low, and you keep getting crappy hands, you may have no choice but to
bluff.
My theory is that software rewards aggressive players - I know as I have lost to many times with good hands , to aggressive bad ones.
So, keeping an eye on what is flopping out helps when you are down below 10BB.
That way you can at least try to get back up with a mediocre hand. Then, you may also try just raising enough to get the others to fold, and try to slowly built up. ( I have done that to)
If you are way below 10BB - you haven't got much choice but to shove and then pray
