Open Face Chinese Poker: Starting Hand Anatomy

Hand: 9966A
Type: 2-Pair
Subtype: Rainbow
Class: Cooperators
Subclass: Full Cooperators

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.

The hand falls into the class Cooperators, as it adheres to the requirements of seamlessly splitting into two or more rows whose improvement draws originate from separate ranges within the array of unknown cards. The back row's primary draw is the remaining 9966 to complete the full house, while the kicker A♥ can be comfortably set in another row, with a primary draw range of AAA. But in this case the kicker also enjoys unimpeded secondary draws to a straight in either direction (A2345 or AKQJT). Thus the hand is put in the subclass Full Cooperators, as the two pairs do not get in the way of the kicker's draws, and vice versa.

Commonly Set:

What about a middle row flush draw? This is something to be considered in Pineapple OFC (e.g. Dealer with hearts live) but in Standard OFC a flush is very unlikely to occur with this hand contour. Since the flush draw intersects with the back row full house draw at the cards (9♥ 6♥), a middle row flush would be considered a tertiary draw, more likely to be backed into than planned for.

This hand is considerably stronger than some similar-looking hands. Consider 9966A v. 99667. The kicker A is much stronger than the kicker 7 for middle row strength, Fantasyland potential, or front row strength. In addition, the kicker 7 is pinned between the 66 and 99, blocking its secondary draws (to a straight) in both directions.
