I believe them Identity. It's not only about basic strategies, it's also about a pretty good memory,timing of and taking advantage when odds are in your favor based on previously played hands.Also has something to do with getting used to a particular casino's software.Believe me, many differ in gameplay and frequent patterns when it comes to, for example, you or the dealer winning or losing so many hands in a row. Some will hit streaks when you win one/lose one for a few hands, and then change to an example used above.......
