[edit] The Chen Formula

Prior to his breakout 2006 performance, Chen authored the Chen Formula which was published in Lou Krieger's 2000 book Hold 'Em Excellence. The formula ranks starting hands by assigning them a numerical value, as follows:

  • Determine your highest card and score as follows: (only use your lower card for gap and suited analysis)
    • Ace = 10 points
    • King = 8 points
    • Queen = 7 points
    • Jack = 6 points
    • 10 through 2 = half of face value (i.e. 10 = 5, 9 = 4.5)
  • Pairs, multiply score by 2 (i.e. KK = 16), minimum score for a pair is 5 (so pairs of 2 through 4 get a 5 score)
  • Round half-points up
  • Suited cards, add two points to highest card score
  • Determine the gap in the sequence
    • Connectors add 1 point -- applies to JT and lower (i.e T9)
    • One gap, subtract 1 point (i.e. T8)
    • Two gap, subtract 2 points (i.e. AJ)
    • Three gap, subtract 4 points (i.e. J7)
    • Four or more gap, subtract 5 points (i.e. A6)

Sample scores AA = 20 points 98s = 7.5 points K9s = 6 points
