Baccarat is one of the oldest table games offered in casinos. Unlike other well known games such as BlackJack, there really is no decision making process involved in playing Baccarat. It is a bit like slots games in that way, especially the online game, as you simply click a button to deal the cards and win or lose according to the outcome. You don't have anything like the options in BlackJack, such as Double Down or Split. You simply make your bet and see the result.
While that takes any element of skill out of the game, it does make it ideal for using strategies and systems with. Any game that has odds close to evens (1:1) can be used for systems.
BlackJack can be quite good for using systems with too, except that the more you play the more likely you are to make mistakes. In order to get close to evens in BJ you need to play optimal strategy, so making mistakes reduces your odds quite a bit. With Baccarat, you simply click the button to deal the cards, and that is all you need to do.
That doesn't mean that using a system is a guaranteed way to make money from gambling. Far from it, in fact. Gambling strategies do not move the odds in your favor one bit.
As the odds of any casino game are in the casinos favor, you will always lose in the long run. The key to using betting systems is, then, to avoid the 'long run'.
