Question

Of all the 21 card counting systems, which is the most effective while still being fairly simple?

Answer 1

Of course that depends to some extent on where you draw the "fairly simple" line. It can also depend upon the house rules.

I use the Braun +- count. (+1 for 2,3,4,5 or 6 and -1 for 10 or Ace.)

I have seen evidence that the Hi-Opt I count (+1 for 3,4,5 or 6 and -1 for 10) is more effective so that would be my recommendation if you are learning counting for the first time.

The Thorp Ultimate count is probably the most effective, but I don't think anyone would call it relatively simple.

Answer 2

plus / minus system

Answer 3

Look up "unbalanced" counting systems. These are the simplest because they do not require you to compute a true count, you just have to keep a running count. The KO count is the most popular one I can think of off the top of my head.

Answer 4

just keeping it simple is the key.  using your memory is the key, just knowing what's been discarded.  Knowing your odds is a key factor also.
