There is a brief discussion about betting techniques in the sticky thread called
An Introduction to Card Counting (Please Read Before Posting New Threads). The
Free Counting Resources On Web thread also has some good info, specifically the GameMaster’s Free Counting Course. Most counting systems will have betting advice in their accompanying book, so HiLo would be Professional Blackjack, KO would be Knock Out Blackjack, Zen and Red 7 would be Blackbelt in Blackjack, etc. Schlesinger’s book Blackjack Attack has some more advanced discussions about betting techniques and bet sizing that should be read before you start playing seriously.
Creating a betting strategy will depend on many personal factors. Different people will play the game in different ways and with different goals/expectations. It is always best to invest your money in a way that makes you happy and comfortable instead of following what other people are doing. Their situation may be very different from yours.
