I think you are asking about playing with a short stack. There is a description of a strategy for playing with a short stack in
Getting Started in Hold'em by Ed Miller. There have been other discussions of the theoretical advantage of playing with a short stack in the theory forum, in some 2+2 books, in
this Ed Miller article, and in a book by Barry Greenstein.
Nevertheless, playing with a short stack is unfashionable in these forums. If you have a huge advantage over your opponents, playing with a deep stack is likely to be more profitable, and more fun, than playing with a short stack. However, there is plenty of strategy when you have a short stack. Almost all tournaments are played with short stacks. It is a good idea to start with a short stack when you are learning NL, because it simplifies your decisions and you get to go to showdown more frequently.
