New Method For Awarding VPPs
On January 1, 2012, we will be changing the way VIP Player Points (VPPs) are awarded at our ring game tables.
Historically, the VPPs earned in a ring game hand have been split equally between all players that were dealt into the hand. The new method will award VPPs proportionally based on each player's contribution to the pot.
The change is illustrated in the example below:
Five players participate in a hand of $1/$2 No Limit Hold'em.
Pre-flop:
•Player 1 raises to $6
•Player 2 folds
•Player 3 folds
•Players 4 (the $1 small blind) calls
•Players 5 (the $2 big blind) calls
Post-flop:
•Player 4 makes a bet of $9
•Player 5 moves all in for $21
•Player 1 folds
•Player 4 calls
•The remaining cards are dealt, and the $60 pot is awarded to Player 4
The pot is $60 in total. Players 4 & 5 contributed $27 each, and player 1 contributed $6. The total rake on this pot is $3, which is worth 16.5 VPPs.
Under the old method, all five players would receive an equal share of the points, i.e. 16.5 / 5 = 3.3 VPPs.
Under the new method, the VPPs will be awarded as follows:
•Player 1 contributed $6 (10% of the pot) and so receives 1.65 VPPs.
•Player 2 contributed $0 (0% of the pot) and so receives 0 VPPs.
•Player 3 contributed $0 (0% of the pot) and so receives 0 VPPs.
•Player 4 contributed $27 (45% of the pot) and so receives 7.43 VPPs.
•Player 5 contributed $27 (45% of the pot) and so receives 7.43 VPPs.
