Specifically if one hand is 3oak and the other hand is a 3-card flush, which hand wins?
If one hand is a 3-card flush and the other hand is a 3-card straight, who wins?
Played a little with a friend after seeing this thread and very interested in ranking, rules etc
Straight Flush
Trips
Straight
Flush
Pair
High Card
I found a demo of their game online, and my higher flush lost to a straight, but the other combinations would be harder to confirm.

Thanks. I suspected this,but obviously felt a need to check.
Thanks for the link to the demo game. Very interesting Dealer plays this hand J-J-9-7-4 as J-9-4| J-7
and Q-Q-8-3-2 as Q-8-2 | Q-3
The worst hand dealer can have is JJ-532 (no 3-card flush). It will qualify and dealer will arrange it as J32 | J5.
btw is there any idea of House Way, otherwise I might find myself doing some fun-time coding sometime. I can imagine with AKQ42 it might be best to play A42 and KQ.
Quote: charliepatrick^ Thanks for clarifying that - I read is as "A 10" high rather than a 10 high so had been totally confused by some of its decisions and gave in playing! That also explains why it would split large pairs.

From the video, house way is to maximize the two card hand while "not fouling" the three card hand. I interpret not fouling as not having a three card hand that is lower than the two card hand. There are definitely some very non-optimum moves implied by this house way. House way is meant to be simple for the dealers to learn and to minimize mistakes on.
AsQsJd9c3s is arranged as As6c3s- QsJd and not as AsQs3s - Jd9c
AsKsQsTd9h is arranged as AT9-KQ, which makes sense since AsKsQs-Td9h would be an automatic push.
Quote: gordonm888This game seems to have a very high frequency of pushes. I suspect it's greater than 50%. You automatically push on dealer hand when his two card hand is 10 high or lower. That happens a lot. Plus, of course it's quite frequent that Dealer and Player will split, i.e., each wins one of the two hands.
The worst hand dealer can have is JJ-532 (no 3-card flush). It will qualify and dealer will arrange it as J32 | J5.

I believe it would be J52 / J3. The bottom hand still must be stronger than the top.

You are absolutely right. My error.
House Way assuming always makes Best Lo
(i) Quads : always split to put Pair in Lo hand
(ii) Full House : always put Pair into the Lo hand and Trips in Hi hand (AAA/KK KKK/AA)
(iii) Trips
- (a) if Pair in Lo leaves a 3-card hand then do that e.g. (JTTT9)
- (b) else put two highest ranked cards in Lo and add remaining card to the pair
e.g. AAAQJ AAJ/AQ, AQQQJ QQJ/AQ, AQJJJ JJJ/AQ
(iv) Two Pairs : Put lower Pair in Lo hand
(v) One Pair : similar idea to Trips
- (a) if Pair in Lo leaves a 3-card hand then do that (TT654)
- (b) if the two highest ranked singletons are not part of the pair, put them in Lo hand (AQTT6)
- (c) if the highest ranked singleton is not part of the pair, the two highest ranked singletons go into Lo hand (K9932 992/K3)
- (d) if the Pair uses the highest ranked cards, then split the pair ensuring Hi>Lo (JJ532 J52/J3)
(vi) Five unmatched cards
- (a) if three of 2nd thru 5th cards can form a 3-card hand, create the best Lo that keeps a 3-card hand in Hi (AQJT8 QJT/A8; AsQhJdTd6d JT6d/AQ; etc.)
- (b) play 1st,4th and 5th in Hi, and 2nd and 3rd in Lo (AKQT9 AT9/KQ)

Are you sure? The dealer is allowed to make his low hand higher than his high hand? J5 is higher than J32. If you do that in ‘regular’ 7 card Pai Gow that’s a foul hand.

This statement is incorrect: " if three of 2nd thru 5th cards can form a 3-card hand, create the best Lo that keeps a 3-card hand in Hi (AQJT8 QJT/A8; AsQhJdTd6d JT6d/AQ; etc.)"
Dealer must go all out to make the best low, even when it busts up a flush or straight in the bottom (high) hand.
Example from demo game: AsJd5s4d2s is is played as As4d2s : Jd5s rather than As5s2s : Jd4d. Dealer breaks up his 3-card flush just to obtain a J5 rather than a J4. This kind of non-optimal play by the dealer is apparently part of the advantage given to player.

I think it’s a tiny, inconsequential error on your part. But this is WoV, where quibbling over minutia rules!
I guess what I could do is, rather like peeking at Blackjack, look at the hands where the Dealer qualifies.
What seems interesting is with AAAAx you would play AAA/Ax not AA/AA (obviously Dealer can't make any Ax) - this may be different if the Dealer folds some hands.

Win: 4
LOSE: 5
DNQ;Push: 5
Push (dealer qualifies): 11
So, 16 of 25 hands ended in push. I realize the sample size is small; but one can still be informed with reasonable confidence by small samples when the results are extreme.
EDIT: Results for 50 trials
Win: 7
Lose: 9
DNQ PUSH: 13
Qualify Push: 21
Obviously, both high and low hands that are 10 high or lower never win, because of the DNQ rule for dealer. But we can use your results to make some back-of-the-envelope adjustments and gain some insights.
DNQ is all hands which do not qualify. Hands such as J-high assume that half beat Dealer's J-high, and half lose.
As always I've haven't had a chance to check these figures nor compare them with a simulation. So please don't take them as gospel!!

Thus if player has AAJJ5 and the dealer has AAKK8, then the player's hand is arranged as AAK | K8 so that the player can at least win the high hand and gain a push.
And, of course when dealer has a DNQ the hand is an automatic push.
First let's look at hands where the player has a low hand that is 10-high or lower and thus cannot possibly win against a dealer hand that has qualified.

Now let's look at some hands with multiple high cards, including hands with high pairs (JJ to AA). The high pair hands benefit from being able to be arranged as "the pair in the bottom hand" or "splitting the pair between the bottom and top hands", depending upon what is seen in the dealer's hand.

AA pair + High Card | AA-Q96 | 0.17648029 |
AA pair + High Card | AA-K96 | 0.227085301 |
Notice that an AA-T96 has a higher EV than an AA-J96. This surprising result is due to the AA-T96 hands facing a lower frequency of Dealer DNQ than the AA-J96 hands. Having a 10 or 2 in your hand has a significant influence toward lowering the Dealer's DNQ frequency.
More in my next post (including 5-card hands with higher EVs) which will be a bit later.
So, given this new analysis capability, let's ask: What is the best hand that player can get in 5-card Pai Gow Poker?
Well, that should be easy. Let's give this hand a Royal flush in the 3-card bottom hand, and a pair of aces in the 2-card top hand. Like this
Nothing can beat or tie the AA because there's only one Ace left in the deck. And the royal flush can't be beaten and it can only be tied by another royal. And another royal would be even rarer than usual because there's only one ace left in the desk. And also because the dealer's house way would split a royal as an ace in the bottom hand and a KQ in the top hand - unless the 4th and 5th cards are a KQ or a pair 22-JJ (remember that all the aces are now gone.) So, this hand is very close to unbeatable. Here we go with the calculation:
Huh??? Crap, this was not what I expected. The dealer must be DNQ at about 37%!!!!!
Well, I realize that AKQ-AA is chewing up 5 of the 16 high cards, and that the dealer often needs two high cards to qualify. So, I start to wonder if Ts9s8s | AsAd might be a better hand? Straight flushes are uncommon enough that a T98 straight flush might not be a very big penalty. And I'll line up the suits such that two suits still have 13 cards remaining. So, I do the calculation and get
Wow, More than a 10 point improvement. Wow. But, can I do even better? What if I boldly chuck the AA for two cards that are 10 or less, so that I have all 5 cards at 10 or less and thus all partially blocking the DNQ. So, here's what I got:
So there it is: (Ts9s8s | TT) is the best Player hand in 5-card Pai Gow Poker! I've always thought of poker as being a game of high cards. But this makes sense: high pairs JJ-AA are quite rare in the 2-card low hand and straight flushes higher than T-high occur infrequently. Avoidance of the Dealer DNQ in 5-card Pai Gow is a very influential factor.
Quads are a rare hand in 5-card Pai Gow Poker, but they are an interesting card category. The quads are usually split into two pair like this: 6666-9 --> 669 | 66. But the player may elect, after seeing the dealer's hand, to split them into trips and 2 singletons: 6666-9 --> 666 | 96. This arrangement might be used when facing a dealer hand such as QsTs3s-88 in order to convert a losing hand into a push.
And it turns out, to my surprise, that the usually irrelevant singleton kicker in a Quads hand can actually be quite significant because it affects the strength of the two card hand when playing Trips in the 3-card hand.
KKKK-T--> KKT | KK or KKK | KT
Here's a table of calculated EVs, where the columns headed by 6 to A denote the singleton kicker in the player's quad hand. I 've kept the entries to only 4 digits to make it easily readable.

I've only been looking at this hand and have been trying for several days to get to your figure. However, having tried three different methods, I get a higher figure. I did play around and wondered whether you had considered a hand, such as Js 9h 7h 5d 3h where there is a 973 flush meaning the J5 qualifies, as this seemed to find quite a number of qualifying hands, typically where there is one-high card which can go into the Low hand due to a flush with three lower cards, and accounts for most, but not all, of the difference. (I guess there's similar logic with something like 66653 where 653 is a flush.)Quote: gordonm888...AsKsQs | AhAd___ EV = +0.62600664
My first approach was to categorize hands by Quads, Full Houses etc. Eventually, since it didn't take that long, I just used brute force such as do I=1 to 48, do j=i+1 to 49... do m=l+1 to 52; and after finding a bug with Full Houses, they agreed.
Within this loop I look at all ten ways to set the Dealer's hands, setting lo1,lo2 hi1,hi2,hi3 mazimizing the low hand while keeping it valid.
/* Evaluate Low Hand */
thislow=n2*drank[lo1]+n1*drank[lo2];
if (drank[lo1]==drank[lo2]) {thislow=pair+n1*drank[lo1];};
/* Evaluate High Hand */
thishigh=n2*drank[hi1]+n1*drank[hi2]+drank[hi3];
if (drank[hi1]==drank[hi2]) {thishigh=pair+n1*drank[hi1]+drank[hi3];};

Here's the tail end of my results for AKQs AhAd, showing how setting the Player's hand fares. (0) uses the best option having seen dealer's hand - in this case it's always best to set AA/AKQs! Note I have assumed the 62 ways of Dealer having Royal Flush, which leads to Tie/Win counts as a Tie rather than a Win. (It's easy to change the code!)

Thanks for checking me.
I certainly intended to rank the dealer no pair hands with a flush the way that you indicate. I'll check my spreadsheet and see if I made such an error.
As you know with ABCDE, if there's no better solution, it will be turned into BC with ADE. So the calculations have initially to look at whether CDE can form a flush or straight, enabling AB to be the low hand. Then this is repeated for AC AD AE before accepting BC is the best low. I encountered some difficulty with flushes, for instance for (AC)BDE to be a flush (AB)CDE musn't have been, etc. Also where there's a straight, that mops up all the non-flushed hands as well.
I haven't yet tried a spreadsheet approach, so I might look at that.
For a one pair hand in which no card is higher than a ten and for which the singletons do not form a straight nor flush, I also score it as a DNQ without arranging it into high and low hands.
Similarly, for a 3oak hand in which no card is higher than a ten and which does not contain a straight nor flush, I also score it as a DNQ without arranging it into high and low hands.
So its not straightforward to compare it to your numbers, I would have to bypass these calculational short-cuts and designate the low hand for those hand categories. But I might do that.
******************************************
I did a lot of error checking last night and found a number of errors that affect small numbers of hands, but the EV for (AKQ)s-AA is still a bit higher than 0.62.

You'll notice that after correcting errors I am getting a somewhat lower EV; i.e. a somewhat higher DNQ fraction. The dealer hand categories "2 pair", "Boat" and "Quads" always qualify and thus (AKQ)s-AA hand has an EV =1 for those.
In fact I've juist realised, if the two highest cards are in {AKQJ} the hand will qualify, if the two highest cards are in (10-2) then the hand can't qualify, so technically only the middle ones are worth worrying about!
So I looked into this approach, then organise the "middle ones" where there is a low or mid straight X8654, X9873, X6543. Then the rest can only qualify if there's a flush in the lowest four cards, and the ways to do this depend on whether the highest card is an Ace (only one around), K/Q (three around) J(four around).
With hands such as Axxxx Kxxxx Qxxxx Jxxxx there are 1,3,3,4 of the high card and 4*4*4*4 of the low card. The suit of the high card is irrelevant as it's needed for the Low hand, so the flushes are CDE (16 ways) BDE (12 ways) BCE (12 ways) BCD (12 ways) i.e. 52 of the 256 ways for each perm.

Quote: charliepatrickI've created a spreadsheet only worrying about the Lo Hand for the No Pair hands, (I hope to move onto the other types later). btw I get 425064 hands where the Dealer qualifies, which is 720 more than yours. My guess is these need to be hands where the highest card ={AKQJ} but the second one is 10-2. For instance AT97x there are 12 ways to get T97 flush, four suits and three ways x<>suit. (97x 16 ways, T7x 12 ways, T9x 12 ways, A7x I don't care whether it's flushed or not) as the lo hand is T9.

I'm struggling with your definitions, but I think this is what I get by interrogating my worksheet for ABCDE hands:
At least two high cards = 271760
Low straight (CDE) = 59392
High Straight (BCD) = 44,608
Those values for straights don't include 4 and 5 card straights, just 3 card straights.
However, there is double counting. Hands with 2 or more high cards that have a CDE or BCD straight are included in in both Two High and in one of the straight categories.
If I understand correctly what Ax and Kx mean (Ax = No pair, A high + 4 singletons that are 10 or less, no straights except for ABC (AKQ) and DEA (32A) straights which are included because they don't allow the Ace to be arranged in the 2-card hand), then I get:
Ax Qualify 4770 DNQ 18270
Kx Qualify 13770 DNQ 55350
Once again, I separately partition hands with 4 card and 5 cards straights (as well as 4 card and 5 card flushes), so that some of these discrepancies may be caused by different terminology or definitions.
For two low, I get: 129024. Which agrees!

Middle Hands which only have one of AKQJ. They only qualify if that card can go into the Low Hand.
Part 1 : see whether a straight can be made with the lowest four cards.
Once I've ignored the 2-High and 2-Low hands the "LoStr" is where CDE makes a straight (since the low hand can't be better than AB). "HiStr" is where BCD makes a straight (but CDE didn't). Note with middle hands, once either straight can be made, the hand qualifies since the Low Hand can use the highest card. Note that it is impossible for an A23 straight to be interesting as it would be ADE leaving BC in the low, which, for middle hands, doesn't qualify.
Part 2 : After removing 2-high, 2-low, Straight possible, this leaves hands of Axxxx Kxxxx Qxxxx or Jxxxx where x are all low cards, and in this case all four suits available. In hindsight it doesn't matter what the High card is since it needs to go into the Low Hand to qualify.
For each high-card (A,K,Q or J) and the other four ranks, there are 256 ways for the suits of the low cards. If any three of the low cards are the same suit, this creates a flush, allowing the High card to be used in the Low Hand.
For any given suit (y) and the other card's suit (x) there are the following five ways for a flush to occur
(i) yyyy - 4 ways (i.e. each suit)
(ii) xyyy - 12 ways (each suit for y, three other suits for x)
(iii) yxyy 12 ways
(iv) yyxy 12 ways
(v) yyyx 12 ways
4+12+12+12+12 = 52.
Therefore 52/256 of these hands can create a flush using the lowest four cards, so can qualify, and 204/256 won't qualify.

I follow your logic.
A Long-winded Caveat
For 5 card hands with 3 card poker hands a factor, I divide and reorder the 1287 no pair hands into 11 different categories of straights:
1x "No straights"
2x 5 card straights: ABCDE; BCDEA (specifically A5432)
3 x 4 card straights: ABCD; BCDE; and CDEA (Ax432)
4 x 3 card straights: ABC; BCD; CDE; and DEA (Axx32)
1x Two 3-card straights, specifically AKQ32
I then take each of the 1287 ABCDE hands in the 11 straight bins and subdivide them (and their combinations) into 16 Flush hands:
1x No flush
1x 5-card flush
5x4 card flush, ABCD; ABCE; ABDE; ACDE; and BCDE
10x 3card flush: ABC; ABD; ABE; ACD; ACE; ADE; BCD; BCE; BDE; CDE
In order to efficiently calculate composition-dependent probabilities/combinations I array these 1287*16 hand categories not as a vertical list but as a matrix with Ranks in the row labels and flush categories in the column labels. And I will have one such matrix for combinations; a 2nd such matrix for bottom hand score, a 3rd matrix for top hand score; etc.
So with the ranks reordered and sub-divided into 11 straight categories, and with an over-all matrix of 1287 *16 hands for ABCDE hands its actually difficult for me to search for the probabilities of hands the way you define them. So the numbers I reported for comparison were not rigorous results that my spreadsheet was programmed to calculate. Example: For number of combinations of hands with 2 or more high cards I simply scanned the 11 sub matrixes containing a total of > 20000 hand categories and manually added up the number of combinations in the probability matrix based on the hand definitions. So, my initial suspicion is that, where I disagree with you it is because I made errors when manually scanning my matrices and compiling the combinations.
I've been busy, but I'll go back and work these comparisons by generating more rigorous results for comparison with your numbers and trying to track where our disagreement is arising from.

Quote: charliepatrickUsing similar logic here are the Middle Hands which can make a straight. Note the hands consist of one of the eleven High cards and four cards 10-2. As an example the 432 straight can have each of those in four suits, then any card from 5 thru 10, then any of 11 High cards. When it comes for BCD forming a straight, E cannot be one less than D (as these have been counted, e.g J5432).

Okay, I have been able to confirm that my spreadsheet agrees with these numbers. For hands with one high card and a low straight, I get 59136. For hands with one high card and the middle straight I get 42240.
Part of my initial confusion was that these hands must have only one high card. I think I am now tabulating this correctly according to your methodology

Therefore 52/256 of these hands can create a flush using the lowest four cards, so can qualify, and 204/256 won't qualify.

My spreadsheet agrees with the 52/256 and 204/256. Remember that with a 13 the combinations 52 and 204 have to multiplied by 3 and with a 12 & 11 they need to be multiplied by 4.

My No Pair calculations now agree precisely with yours. Your numbers are equivalent to an EV(NoPair) = 425064/756048 = 0.562218272, just as mine are.
My Total EV has changed from 0.6204 to 0.6209. However, still not in agreement with your 0.66.
I am reviewing my 2-pair worksheet and I'm going to be revising some of my calculations for hands with 3-card flushes. If I have an error, that may be where it is.
Thus you can see at least 467964 should qualify.

(i) Must qualify = 19358
(ii) The remaining are 252 ways with 4*4*4 suit options.
I get 21 of these are straights (e.g. trips 8 with T9/97/76 etc) = 21*64
Of the other 231, 12 of the 64 suit ways produce a flush {sxx,s,s} four suits and three ways to get xx suits of the trip = 2772.
So...
(i) 19358
(ii) 1344 (21x64)
(iii) 2772 (231x12)
= 23474

So with errors corrected, the calculated EV of this hand has gone from 0.6208 to 0.6252. Still, Dealer DNQ is still >0.37.
Low pairs so all the cards are 10 or lower.
Thus there are 9*8*7/6 = 84 ways to pick the three singletons
Then there are 6 unused ranks, so six ways to pick the pair
The suits of each singleton can be any of 4 suits,
There are six ways for the suits of the pair.
Hence suits = 6*4*4*4 = 384
You can see 84*6*384 = 193536
16128 =7*2304 Of these 84 ways, 7 are straights (T98, 987, … 432)
11088 = 77*144 The other 77 ways, there are 144 of 2304 ways to make a flush .

I get Qualify = 30996; DNQ = 162540. You get DNQ = 166320? ,if I am reading your post correctly?
**********************************************************************************
For 1 pair hands, I found a truly grievous error in my hand scoring whenever the second high card was paired. I fixed it and I now get Qualify (and WIN) = 496008 where as you get Qualify = 495180.
In my spread sheet there are a small number of Push hands in 1-pair where the dealer qualifies with three singletons that are suited AKQ. I think that only amounts to 60 combinations.
In Trips , my spread sheet also has two hands that qualified but Player pushed - where the dealer hand is suited AKQ-KK and suited AKQ-QQ. I think that implies that our DNQ/Qualify number for Trips do indeed agree!
*****************************************************************************
Thank you so much for giving me these benchmarks. At least we are now much closer. Obviously, I have still have more debugging work to do on the one pair worksheet.
2-pair Qualify (and Win) = 494175
2-pair Qualify = 494235 (accounting for the 60 1-pair hands with a royal in the bottom hand that qualify and push)
charliepatrick's calculation for 1 pair qualifiers = 495180.
So, still a discrepancy. At this moment in time, I have no idea,
On low 1-pair hands where all cards are 10 or lower I am now getting DNQ = 166320, which is the same as your number.

My results for the Return against Dealer's 1 pair hands is 495120. That is 60 combinations less than Charlie's result because I calculate that Dealer has hands with 60 combinations that qualify but TIE against the royal flush in the 3-card hand, thus changing the outcome of those wagers to a Push.
Many thanks to charliepatrick for his excellent work providing me with benchmark results for this case!
