JUMBO PINEAPPLE OFC


August 15, 2015 -- So, we went into the laboratory and didn't come out until we created the Frankenstein of OFC - Jumbo Pineapple!



It plays exactly like Pineapple (except you use all 3 cards on the very last pull), with the notable exception of having a mega-tower of 4 rows - all using 5 card hands!

For those of you who needed more than just regular Pineapple. It's Jumbo.




Don't Rush the Flush - Part I



July 21, 2014 -- ABC app creator Nikolai Yakovenko tweeted out the following Pineapple Open Face spot the other day:



Response was varied, with some saying complete the flush, and some saying pair the 8's. But is there an optimal way to play this spot?

Flushing the back here allows for a middle-row flush draw 85cc. It also completes the back row flush and 4 point royalty, adding equity to the hand. On the other side of the argument, pairing the 8's in the middle and adding the kicker 5 or J allows for a two-pair-or-better middle, opening the door to a big-pair, Fantasyland-inducing front row.

So what are the odds and strategy for either play?

A) PAIR THE MIDDLE: If the flush is denied here and 885 or 88J is set in the middle, the flush still is completed 90% of the time, 90% being the equivalent of a slam dunk in poker. Remember there are still 9 cards to come, with 8 live diamonds. Additionally, the chance to two-pair the middle is 75%, with a 41% chance to hit trip 8's for a +2 royalty. Setting the pair also takes a big lead in the middle row, adding scoop equity to the equation.

B) FLUSH IT OUT: If, on the other hand, you complete the flush here and set 85cc in the middle, you are well under 50% to draw the 3 clubs you need to complete the 2nd flush. And now 2-pairing the middle is only ~30% likely to happen, drawing to runner-runner 8's and 5's, and trips is now 13% at best, drawing to the 555 set.

THE ANSWER IS A: You lose ~45% middle row and scoop equity as well as 28% middle-row-trips equity, to gain a 10% likelihood in completing the back row flush. Even if you look at the opponent board and see they're in a tough spot and likely to foul (so why not get greedy and go for the middle row flush), you're giving up a lot of potential Fantasyland EV by not setting the pair. There's no guarantee you'll catch QQ or AA in the front, but it's even less likely you'll catch those cards AND make your middle row flush (remember also that any A or Q of clubs would probably go into the flush draw).

After looking at the math, it's a clear case to pair the 8's in the middle.

In other words, don't rush the flush!

ALT LINES: 2-7 PINEAPPLE HAND


April 6, 2014 -- This Alt Line analyzes 3 different sets of the hand pictured below. The starting 5 cards are classified as semi-cooperators, and cooperate they did (except in one set, showing in this instance the risk of playing too conservatively in Pineapple OFC).

As in the all the Alt Line series, hand scoring is broken down into royalty equity, scoop equity, and Fantasyland EV.




HOME GAME UPDATE


March 31, 2014 -- Last night's Open Face Chinese session went down 3-handed, and featured these variations in a dealer's choice rotation:
  • Pineapple
  • Pineapple 2-7
  • Turbo Pineapple
  • Turbo Pineapple 2-7
  • Catch-44 (see last week's post for rules)
  • Catch-44 2-7
  • Turbo
  • Turbo 2-7
As you can see, 2-7 was the new addition to the mix. This variation features a lowball middle, with KK+ to qualify for Fantasyland. The middle must be 10 or better, and a perfect 75432 takes you to Fantasyland as well. Fantasyland was dealt 14 or 15 cards, depending on the quality of the FL make: KK gives 14 cards, AA+ and the 75432 give 15. Fantasyland repeats are the same as Pineapple: trips in front or quads+ in back (lowball middle must be placed while in FL).

9-high middle is worth 1 point, 8-high is 2, 7-high is 4 points, and we gave 6 points for the 75432. Since you lose the flush and boat royalties with the introduction of the lowball middle, some compensation was given. We considered a 10-point royalty for the perfect lowball, but it seemed to hit very often so we settled on 6 points, the same score as a back row full house, or JJ up front. In our rules section we have put it in as a flexible 6-10 points to be decided on by individual house rules.

Oh yeah, and the worst Fantasyland we've ever seen!



We play variable-value Fantasyland for all Pineapple games, so QQ gets you 13 cards, KK-14 and AA-15. Needless to say, this hand didn't fare very well.




HOME GAME UPDATE


March 24, 2014 -- Last night saw a 3-handed Open Face Chinese mix at the OFO house game, with the following variations in rotation, selected by dealer's choice:

  • STANDARD: The 'original' version, dealt 5-1-1-1-1-1-1-1-1
  • TURBO: Dealt 5-4-4 (set all cards)
  • SEMI-TURBO: Dealt 5-2-2-2-2 (set all cards)
  • PINEAPPLE: Dealt 5-3-3-3-3 (discard 1 of 3 post-deal)
  • PINEAPPLE TURBO: Dealt 5-6-6 (discard 2 of 6 post-deal)
  • *PINEAPPLE SEMI-TURBO or **CATCH-44: Dealt 4-4-4-4 (set the first four, discard 1 of 4 post-deal)
*Invented by the OFO research team **named by Q-Tip Josh.

Variable-value Fantasyland was used in each game, so QQ got you 13-card Fantasyland, KK 14 and AA+ 15.

Catch-44 was a popular choice throughout the evening, as were Pineapple and Turbo.

The following variations are available in play-practice modules on Open Face Odds:
STANDARD OFC
PINEAPPLE OFC
TURBO OFC
PINEAPPLE TURBO OFC

Stay tuned because we will be creating Semi-Turbo and Catch-44 play modules soon.
