The list of ev's vs all possible hands would be more meaningful, although I have never seen one. [/ QUOTE ] http://www.jazbo.com/poker/huholdem.html http://www.gocee.com/poker/HE_Value.htm |

If you look down at KK, there is really only one hand you don't want to see, and you will crack it anyway about 17% of the time. So, you would be willing to pay (6/1326)*.83*$1000=$3.76 to see his cards. [/ QUOTE ] You should be using 1225, not 1326, because the two cards you are holding are not available for the other player to hold. [ QUOTE ] By this same reasoning, there must be some justification to paying a tiny amount even with AA, if you think it is unwise to gamble against the other AA. [/ QUOTE ] It might reduce your variance by a minuscule amount, but it would also reduce your EV (by the amount you pay). If you are seeking to maximize EV, then you would not pay anything when you hold AA. |

If you code this, it would be good to make your code general enough to answer Pure Theory Questions #2 and #3.

That's easy, for #2 you just split the hands into the < 40% and > 40% vs a random hand (of course taking dead cards into account)
For #3 you do the same with hand < 22.22% and > 22.22% vs a random hand |

Here's what I found.
Without the dealmaking, EVI[x] denotes the expectation value of your winnings when you have hand x. Clearly, for all hands that have an equity lower than .5 against a random hand, this value will be 0. For hands with EQ>.5, it is 1000*(2*EQ-1). Let EVII[x] denote the same, but now under the assumption that you get to see your opponent's hand before making your decision. This means that EVII[x] equals Sum{y=1..169}: P(opponent has hand y given you have hand x)* { 1000(2*EQ[x,y]-1), if EQ[x,y]>.5 { 0, if EQ[x,y]<.5 Here EQ[x,y] denotes the equity of hand x versus hand y. Note that for all x, EVI[x]<=EVII[x]. Since it shouldn't matter for both whether the first game is played, or the second one (where you pay to see your opponent's hand), the amount that should be payed when you hold x would be EVII[x]-EVI[x] So, here's a sorted table: AAo 0 32o 0 32s 0.24645061119224881 42o 0.49362920679162253 42s 1.2115147968194 43o 1.5270018808409391 KKo 3.129409025404243 43s 3.350338229088077 52o 3.527280393277474 52s 4.898684307631056 AKs 5.180016670700013 53o 5.577367436756899 QQo 6.218631595267539 62o 7.801543822754339 53s 7.842160299210643 54o 7.991409021209468 AKo 8.612611893634153 JJo 9.271872570405549 AQs 10.403735289423992 62s 10.886796565401026 54s 11.326334194710027 63o 12.00972133309915 TTo 12.287896236621066 AQo 14.706253285941273 72o 15.037341738478267 99o 15.328348141880099 AJs 15.451208740160098 63s 15.501353850765788 64o 15.992477780504743 88o 18.317801092348247 64s 19.82958776536152 ATs 20.231383193256818 72s 20.413498003692286 AJo 20.59982339584593 65o 21.225719312477604 77o 21.3849667358312 73o 21.83522151607259 66o 24.547986043294316 65s 25.55751925416258 ATo 26.187359730705623 A9s 26.627246811600315 73s 27.384889789739766 82o 27.532403649094572 55o 27.885729236330064 74o 28.235451133891708 KQs 29.578990932565944 A8s 30.592463459187087 44o 32.08376502284227 83o 32.8375154059045 A9o 33.72238927247432 74s 33.92100124887223 A7s 34.436049501796504 KJs 34.99541040871836 75o 35.30181175152761 82s 35.663389735677306 33o 36.868416079463714 A5s 37.132510896882735 A6s 38.196752588849165 A8o 38.49263701219604 A4s 39.92909660710663 KTs 40.13759715755259 83s 41.039884010678236 75s 41.108788902828785 84o 42.07177830905857 A3s 42.380391732843265 92o 42.640624466645356 22o 42.80234808581603 KQo 42.9525760350387 76o 42.954186944870166 A7o 43.13894338045273 A2s 45.01100987026729 QJs 46.27455958135147 A5o 47.08036537856785 A6o 47.724989135059246 76s 48.9960575377517 KJo 49.1476599329778 93o 49.87199726693582 84s 50.138481989942264 A4o 50.63148142109452 K9s 51.67411575400203 QTs 51.74431213911842 85o 51.90216366309929 A3o 53.805121100944916 92s 54.022055686850194 KTo 55.02402110172642 94o 56.14166738654646 JTs 56.63731702419395 A2o 57.1809054123716 85s 59.89297246664765 T2o 59.954161296172614 K8s 61.07861259044009 86o 61.07891579809116 93s 61.18028726922605 K7s 64.70417183216134 94s 67.39790626535704 Q9s 67.81813443006848 QJo 67.83067511757838 K9o 68.25273540021789 K6s 68.50272534097024 T3o 68.66742287417588 86s 69.20063402817468 95o 69.27160178118285 87o 71.99892170587292 K5s 73.21627038952255 QTo 74.07158198687222 T2s 75.1875272577004 J9s 76.80402545342506 T4o 77.25945240316851 K4s 77.57919297565135 J2o 78.0379561630387 K8o 78.96263080120625 T9s 79.07159914956912 87s 80.07425917694187 95s 80.13169938734896 Q8s 80.97832713664697 96o 81.1433507610989 K3s 81.59441361833392 K7o 83.3215225371956 T3s 83.7048375541173 JTo 85.20727341759478 K2s 85.73284574110565 T5o 85.92617160675837 K6o 87.97846834750511 J3o 88.25879383233686 96s 91.91253660660293 T4s 92.10019258453244 Q9o 92.29328103287388 J8s 93.30496482505136 K5o 93.51652844020992 97o 93.7318635580827 Q7s 93.75806241539058 Q6s 96.5461020558811 Q2o 97.56498702976825 J2s 97.85897020765522 J4o 98.34612240321235 T8s 98.65421331821494 K4o 98.76625712657241 T5s 100.51456483695156 98s 101.08971018116 T6o 101.17919505424462 Q5s 102.1512968992159 K3o 103.64825214137984 97s 104.46927982080614 98o 106.50722473274342 Q8o 107.12012658061255 J3s 107.75741662123318 J9o 107.7688460240992 Q4s 108.03805675551456 K2o 108.67439760362949 Q3o 109.3191281502369 J7s 109.5276220263004 J5o 109.78468824246538 Q3s 113.59733232569201 T6s 115.37911826070946 T9o 115.39549719475704 T7o 116.77052958934807 J4s 117.5250432356948 T7s 117.93065450327212 J6o 118.5506879285788 Q2s 119.30003703328696 Q4o 120.92699827667448 Q7o 121.454421787777 Q6o 124.9702994757174 J6s 125.0165682004588 J8o 126.28830642508485 J5s 128.53511611804197 Q5o 131.47232724839463 T8o 131.5444739833533 J7o 138.04610272331956 According to this, the K2 feeling is quite off.

Thanks for doing that calculation.
Your numbers are slightly off, since you didn't consider the combinations of suits. That can make 32o a favorite over 32o, for example. It also determines whether A7s is a favorite over 22 or not. The differences shouldn't matter enough to affect the calculation of the best hand. |

I think the biggest factor we have to put into consideration here is that he moves all in "in the dark". Everyone is talking about tight players and loose players and what he could have and what he couldnt have...but he himself doesnt even know what he has. Therefore, if you have any huge hands, AA, KK, QQ, AK, etc.. you dont pay him anything and take your chances because more often than not you will be the favorite by a lot with these hands. For example, let us say that you see KK, the only hand that true dominates you is AA, but what are the odds that he has AA. In this situation you take your chances and call with KK without paying anything, since he probably might not even have an ace, not even one over, and if he does, he is drawing to 3 outs. If he has a smaller pocket pair, then he is drawing to two outs. I feel that the best hand to pay him off with in this situation would be a middle pocket pair such as 88 or 99 or two face cards suited such as KQs or QJs. The reason for this is that if you have 88 or 99 and he shows 7 4 you know you are a tremendoes favorite, however if you have 88 or 99 and he shows 10s or better you know you are a severe underdog. Also if he shows two cards above 8s or 9s then you know its a coinflip - and you should not call his all in, never put all your money in on a coinflip - if you want to do that, you are playing the wrong game and should go to the casino and bet red/black on roulette. I hope some of you find this enlightening.

Clearly with AA you call and 32o you fold.
Consider you hold KK: If you call you will win 82.4% of the time with an EV of $648 If you know your opponents cards: He will hold AA (6 of 1225 times), you would fold. And he will not hold AA (1219 of 1225 times), you would call. You would win 82.7% of the time. If you knew his cards your EV would be $654 Then it would be worth paying to see his cards if it was less than $6 Consider you hold 32s: If you call you will win 36.0% of the time with an EV of -$280 So you would fold for an EV of $0. If you know your opponents cards: He will hold a hand better than 32o (1219 of 1225 times), you would fold. And he will hold 32o (6 of 1225 times), you would call. You would win 7.2% of the time, lose 0.4% and split 92.4%. If you knew his cards your EV would be $0.34 Then it would be worth paying to see his cards if it was less than $0.34 Notice that it would be valuable to know your opponents card the closer you got the middle holdings of J5s.
