Open Face Chinese Poker: Starting Hand Anatomy
Subclass: Full Cannibals
This hand type is 2-Pair subtype Rainbow. All rainbow hands will contain two of one suit; in this case the suited cards
are mostly irrelevant to hand's structure, 2-pair most often being set in the back row to draw to a full house royalty.
This hand falls into the class Cannibals, as the configuration provides fewer improvement draw options
The back row's primary draw is the remaining JJTT to complete the full house. The
kicker Q♥ can be comfortably set in another row, but its only realistic improvement draw is QQQ.
In this case the kicker is pinned to one edge of the spectrum by the two pairs, blocking any secondary draws to a straight.
Thus the hand is put in the subclass Full Cannibals, as the two pairs do get in the way of the kicker's straight draws,
and vice versa.
The cannibalistic anatomy is more problematic in a hand like 66442, where 6644 is likely set
in the back row, leaving the 2 with fewer draw options. But as QQ+ qualifies for Fantasyland in most games,
this starting five is adjusted into a more cooperative outlook with the above setting.
Odds to hit the back row full house:
Standard Heads Up: 54% / 59% in position / out of position
Pineapple Heads Up: 71% / 76% IP / OOP
Pineapple 3-Handed: 71% / 76% / 81% UTG / UTG+1 / DEALER
Odds to pair the Q:

Pineapple 3-Handed: 60% / 65% / 70% UTG / UTG+1 / DEALER
