5 Poker data extraction
In this work a large database of poker games is needed in order to cover the largest possible number of gamę situations. There are some desirable reąiusites that must be accomplished in order to ensure data quality. In this case we need a database that has games between human players and preferably games in real money tournaments. As suggcslcd in [12,13], the money factor is rather important because the players tend to be morę careful. because they are risking money. usually using for that reason better tactics.
There are several data sources that might be used to this work. The chosen one was a package of 7.5 GB of casino Client gamę logs1. The following table shows some characteristics of the dataset.
