Poker is a popular gambling game, but most players lose money because they appear to make bets emotionally rather than rationally. Betting by emotion can lead to gambling addiction, where players repeatedly place bets to seek thrills or highs, often resulting in financial losses. The purpose of this paper is to study poker probability using a 24-card AKQJ partial deck for realistic poker situations. The AKQJ game reduces the winning hands to Four of a Kind, Full House, Three of a Kind, and Two Pairs. The experimenters used probability and combinatorics concepts to derive general formulae for each matching card pattern. To simplify probability simulation, a partial deck poker game was designed to increase the matching probability on some higher ranked hands such as the Full House. The system was enhanced to accommodate five players and multiple betting rounds, since these are more realistic poker real-time scenarios that capture how gambling disorder may exacerbate. The experimenters modeled this by assigning players characteristics based on a degree of risk-taking. The experimental results have shown that  more conservative players perform better than other aggressive players. This partial poker game and the results can characterize the choices that spur irrational gambling disorder through exploration of fundamental probability scenarios in poker under the AKQJ model.
