Get the upper hand (also hold sway, dominate, govern, control, and domineer) means having the power or influence to make decisions. This is an essential part of poker strategy. Marked cards are the best way to get the upper hand. They can help you win more games than your opponents. There are several ways to mark a deck of playing cards, but the most common is with invisible ink. This type of marking can only be seen with poker perspective lenses or glasses. These glasses are available on the internet, but you can also buy them in some magician shops.
Another way to mark a deck of cards is with barcode marked cards, which are also invisible to naked eyes but can be read by a poker analyzer. This card reading device will report the winning seat even if cards are spread in the middle. This device can be purchased online or at a casino. In some countries, it is illegal to cheat with poker analyzers.
Marked Cards can improve your poker game or magic performance. But you must use marking devices that are compatible to the cards you’re using. You can purchase poker analyzers and external scanning cameras online, as well as at some magician shops. These devices can be expanded with many accessories. They can be hidden in a variety of everyday items such as watches, bracelets and T-shirts.
