online casino software @koft counting cards gives you an advantage. I suggest you read about it some more. Basic strategy comes close to 50/50 not quite there but close. Counting cards does absolutely give you an advantage. Take a simple card counting system like the KO system and read about it. Basically since you have the history of the past cards that have been played you now know the odds of cards that are in your favor that are in the deck. If there is a lot of them you bet big, if there's not you bet small. The variation of the betting is what gives you the advantage over the house.
