Misclick

Due to a temporary loss of attention, a misclick can happen in online poker, simply by clicking marked cards the wrong button when it’s your turn to act. Misclicks can cost a lot of money.

EXAMPLE “You want to fold, but instead of clicking on the “Fold” button as intended, you click on the “Call” button.”
When playing poker online, a misclick can be easily avoided if you are focused at every table you’re playing at, and spend enough time to make every decision. They tend to occur when you’re rushed making decisions because of multi tabling.
