April 6, 2014 -- Today's Open Face Chinese Poker hand is Pineapple-OFC, with a 2-7 middle. For complete rules and scoring specifics for 2-7, see our Rules Page. Open Face Odds observes variable-value Fantasyland for Pineapple, and in the 2-7 variant, front-row KK qualifies for 13-card FL, AA+ front is 14-card FL, and a perfect lowball 75432 is 15-card FL.

The hand dealt is A8dd Ts 42hh, and is classified as a "Semi-Cooperator" starting 5. A cooperating starting hand can be grouped in separate draw ranges across two or possibly three rows. For an introduction to this concept theory, see Open Face Odds' Classification of Starting Hands part I.

For more theory on the array of unknown cards, discrete and merged draws, and the like, please read our article Elephants in the Room.

Nut low middle scores 8 points in our home game, so it is the measurement here. The hand scores were calculated three times: 1) royalties accrued + scoop equity estimate + Fantasyland EV; 2) against the actual opponent hand it faced; 3) in the case of an opponent foul. Comments for each alternate line are made while the hand is being played and are notated below the sets.

FIRST FIVE





A decent start to a well-balanced and potentially high-scoring hand: two-to-flush in back with 12 cards to see, nut lowball 40% made, and a 10 up front for a 5 point royalty if paired.

Merged draw ranges to watch out for: non-diamond 10's which could possibly be needed in the middle (and diamond 10 might go in back), as well as the 3,5,7, and 9 of diamonds which are a primary draw merge between the middle and back, and the three non-diamond 8's which are a secondary draw merge between middle and back.

A straight Fantasyland grab with the Ace in front. 40% lowball already made, and 8T in back with a primary improvement draw of 8's and T's, and a secondary draw of the straightening cards 6,7,9,J,Q.

Back and middle row draw merges to watch: 8's and T's primarily, 6's, 7's and 9's secondarily. The front row improvement range is generally clear of any other row's draw, as A's and other high broadway will be sought.

This is the most conservative of the three sets, with the lowball middle 60% completed, A in back and T in front. Even though the AT could be placed together in back to go for a broadway straight, the choice has been made to keep the front available for KK or another high-scoring pair.

This is the most cooperative set as well, as the three rows' primary draw ranges are completely separated. However, it could prove to be the most inflexible as well, and potentially the most scoopable.


PULL 1





A wonderful pull for this set, as not only does the flush draw move from 40% complete to 60%, but the nut low middle (75432) is very much alive with the addition of a 7.

Also a good pull for this set. The nut low is live with the 7c, and the addition of the 9 shifts the back row primary draw range to J's and Q's, allowing 8's and 10's to move into secondary draw range in the middle (its primary draw range is 3's and 5's currently).

The conservative plan is moving forward, with an 8-high middle slated to score a 2-point royalty, and still leaving room in front for a big pair.


PULL 2





Another excellent pull, with the flush now moving from 60% to 80% complete, and the middle 80% complete with the nut low live.

Also moving to 80% complete in both middle and back rows, with the nut low live.

Two points sewn up in the middle, with a safe-looking draw to KK in front, and plenty of cards to see.


PULL 3





Things are going from good to great, with the flush AND the nut low arriving in the same pull, locking up ~24 points in value (see scoring at the end of the hand).

The cooperativeness of the starting 5 and set is showing now (with a bit of run good) and this hand has now accrued ~22 points in value.

The inflexibility of this set is starting to threaten overall equity. Still, there is a chance for an AK last pull and the 8-high middle is a decent hedge against a scoop. And if your opponents foul frequently, you're still unfouled, so there's that.


PULL 4





The 10 pairs up for the cherry on top. This pair, while strong, does not guarantee a scoop, which is reflected in the scoop equity number below.


SCORING (GENERAL)
ROYALTIES: +17
SCOOP EQUITY: +4
FL EV: +12.4
TOTAL SCORE: +33.4

SCORING V. ACTUAL HAND
ROYALTY EQUITY: +9
SCOOP EQUITY: +1
FL EV: +6.2
TOTAL SCORE: +16.2

SCORING V. FOULED HAND
ROYALTY EQUITY: +17
SCOOP EQUITY: +6
FL EV: +12.4
TOTAL SCORE: +35.4

Fantasyland was reached, not by the AA front row as originally planned, but by the nut low middle. AQT top has some scoop equity, but is easily beat.


SCORING (GENERAL)
ROYALTIES: +10
SCOOP EQUITY: +1
FL EV: +12.4
TOTAL SCORE: +23.4

SCORING V. ACTUAL HAND
ROYALTY EQUITY: +2
SCOOP EQUITY: +1
FL EV: +6.2
TOTAL SCORE: +9.2

SCORING V. FOULED HAND
ROYALTY EQUITY: +10
SCOOP EQUITY: +6
FL EV: +12.4
TOTAL SCORE: +28.4

This set ultimately erred on the side of 'too conservative'. The 8-high middle was not a terrible idea, but the lone Ace in back at the beginning of the hand didn't leave much room for flexibility when high broadway didn't hit the pulls.


SCORING (GENERAL)
ROYALTIES: +2
SCOOP EQUITY: -1
FL EV: 0
TOTAL SCORE: +1

SCORING V. ACTUAL HAND
ROYALTY EQUITY: -6
SCOOP EQUITY: -6
FL EV: -6.2

ROYALTY EQUITY: +2
