Tracking poker play in a B&M casino is very difficult. You can easily monitor your winnings, but tracking any detailed statistics about your game requires a player to take notes after each hand, which is cumbersome and distracting.

Conversely, tracking poker play online is easy. Most online poker rooms support “Hand Histories” text files which track every action both you and your opponents made during each hand. The ability to specifically track every single played hand has many advantages. Many third-party software applications process hand history files and return detailed summaries of poker play. These not only include exact tallies of rake and winnings, which are useful for tax purposes, but also offer detailed statistics about the person’s poker play. Serious players use these statistics to check for weaknesses or “leaks” (mistakes that leak money from their winnings) in their game. Such detailed analysis of poker play was never available in the past, but with the growth of online poker play, it is now commonplace among nearly all serious and professional online poker players.
