Chinese Poker - Comparing Hands

For regular hands, compare each of the three hands individually. The higher-ranked hand wins. If ranks are equal, compare card values, and if necessary suit order. Hands are compared in order: Front vs Front, Middle vs Middle, Back vs Back.
When comparing a regular hand to a special hand, there's no need to compare each segment. The player with the special hand wins automatically and earns the corresponding bonus points (Water Points).
When both players have special hands, the higher special hand wins the Water Points. If both hands are the same, it's a tie.

Standard Hand Scoring - Rules

Head, Middle, and Tail hands are compared separately; each section earns or loses water points individually.
For each section won against another player, the winner gets water points based on their hand type.
If a player wins all three hands (Head, Middle, Tail) against another player, they score a "Shoot".
The player who is shot must pay double the water points to the shooter.
Example: Player A shoots Player B; if B originally lost 5 water points (with a Three-of-a-Kind in Head), after being shot, loses 10 water points.
If a player wins all three hands against all three other players, it’s a "Grand Slam".
Water points are doubled for a shoot and then doubled again for a grand slam, resulting in 4x water points.
Example: Player A achieves a Grand Slam against B; if B originally lost 5 water points (with a Three-of-a-Kind in Head), B now loses 20 water points.
When standard hands are tied, compare hand rank first, then suit; there are no ties. (e.g. both are Straight)

Special Hand Scoring - Rules

Special hands are not compared by section; instead, they score based on their corresponding special hand water points.
When both players have special hands, the stronger hand wins and earns full water points based on hand type.
Special hands are not eligible for "Shoot" or "Grand Slam"; no water point doubling applies.
If multiple players have the same special hand, they tie. No comparison of hand rank or suit. (e.g. both have Pure Suit)
