Pot equity - forklaring (limit)

I bogen Small Stakes Hold'em af Miller, Sklansky og Malmuth bliver der brugt begrebet "pot equity".

Det bliver forklaret på følgende måde:
Pot equity er et begreb som dækker over hvor meget man selv har inde i potten. For eksempel - har man et draw der vil rammes 10% af gangene, og potten indeholder 5 bets (limit hold'em), så er ens pot equity 0,5 bets. Ergo er det ikke værd at beskytte potten, hvis det kræver, at du skal lægge et nyt bet for at være videre med.

Men hvor går grænsen til hvor høj en pot equity, man skal have før det vil være profitabelt at calle? Vil det være hvis ens pot equity er over 1,0 i det her tilfælde?

Lidt senere i bogen bliver der givet et nyt eksempel:
Du flopper nut flush draw, og du har derfor 35% chance for at vinde hånden efter riverkortet er lagt. Derfor har du 35% pot equity (pot equity kan altså både forstås som den del af penge, du selv har lagt i potten og som den procentdel chance du har for at vinde potten???). Hvis alle fire modstandere kalder turn vil du selv bidrage med 20% af potten, men din pot equity er 35%. 35%-20% = 15% og kaldes "pot equity edge" og betyder, at du har 15% profit på alt flop betting.

Det forvirrer mig, at pot equity begrebet både bliver brugt som procentdel af det, som man selv har af $ i potten og som den procentdel man har change for at vinde. Men det er sikkert mig som misforstår noget?

Er der en som bruger denne form for beregninger i deres limitpoker og som kan dele deres erfaring på god dansk med mig? :)

Og er pot equity et begreb, som kun forekommer i limitpoker eller kan man også tale om det i no limit? Umiddelbart vil jeg ikke tro, at det er særlig aktuelt i no limit?

Jeg bruger det ikke.. men er ens potequity ikke hvor meget men ejer af en pot?

Dvs. dit flushdraw rammer du 35% af gangene, og der er 5 mennesker til floppet. Du regner med at alle call'er et bet og tjener derfor penge på det i det lange løb uanset om du vinder eller ej i den pågældene pot, fordi du udgør 20% af folk til turn/river?

Med andre ord, er du heads up kan det ikke betale sig at bette ud med dit flushdraw pga. potequity, fordi du skal eje mere end 50% af potten før det er profitabelt.

Er jeg helt væk her?

Det er også nogenlunde det jeg går og fundere over, og det lyder jo også logisk nok. Et flushdraw er en drawing hand og gør sig bedst med mange deltagere. Heads up er det high-card hands der er value i.

Men lad os lige få nogle FL profs på banen. Der må være nogle, som kender til begrebet og bruger det i deres daglige spil.

DTM ved jeg spiller FL - har du hørt om det?

Pot equity differs from pot odds in the sense that pot equity usually helps determine when you should bet while pot odds lets you decide whether to call.

Pot Odds

Pot equity’s counterpart, pot odds, is easier to understand. The simplest form of pot odds is expressed pot odds:

Q: You are holding AJ in a heads-up pot, in a $5/10 limit Holdem game. On the turn, the board is K T 4 2. There was $35 in the pot. Your opponent now bets into you, and it is $10 to call. Do you have sufficient pot odds to call?

A: Even assuming the worst case (that your opponent has a pair with an ace kicker, making your outs to the A no good), you have 9 outs to the flush and 3 outs to the Broadway straight (don’t count the Q twice). You know 6 cards, and there are 46 unknown cards. Your odds to win are 46/12 = 3.83 to 1, so you can call the bet. The pot is offering (expressing) $45 to $10, or 4.5-1 odds.

The Next Step: Pot Equity

Understanding the pot equity in various situations allows you to profit by betting or raising in situations where you have a distinct advantage in the hand, or can gain that advantage by not allowing other players to continue.

A prime example of pot equity making your poker more profitable is when you have a large number of outs in a drawing situation. Let’s set up a situation where you have the worst hand on the flop best the highest pot equity. You are holding Q J in the big blind. An early player raises, a middle player re-raises, and you (questionably) call, only to have it capped behind you. Three players see the flop of J T 9. You bet, and it’s a raise and a 3-bet to you. Before you act, both opponents drop their cards on the table, exposing A A and K K. You’re behind to two overpairs. What is your move? Answer: Cap it!

Experienced players are nodding, and newbies are shocked. Here’s the scoop: with 9 known cards, take the remaining 43 cards and deal out the turn and river in every possible way. There are (43*42)/2=903 possible outcomes. You will win 55% of those 903 deals! The AA hand will win 35%, and the KK hand will win 10%. This is because you have flush draws, straight draws, 2 jacks, and running queens as outs.

Applying the known equities to the flop raise above relates the math behind the raise. If I tell you your equity is 55%, you can look at your options after the flop 3-bet. The pot (now) is 9.25BB, or $18.50 in a $1/2 game. Your 55% equity translates to $10.18, or about 5BB. It’s $2 if you call, and $3 to raise. Here is the key: When using pot equity to analyze an action, if your current equity is greater than or equal to the actual current cost of that action, you can correctly take that action.

Notice that I take no consideration of the $5 you had previously invested in the pot. That money is no longer yours; it’s the pot’s. The only choice now is to fold ($0), call the 3-bet ($2), or cap it ($3). Also, the idea of cold calling the 3-bet in order to disguise your hand (knowing that the AA player will likely cap it) is a good one, but not considered here.

No Limit Pot Equity

While pot equity can be used to dissect LHE hands, it is more of a factor in big-bet games (pot limit or no limit), and can even be used to make quick in-game decisions. Consider the following situation: you are heads-up against a player who is near all-in before the flop, with 900 total in the pot. The flop comes with three spades, perhaps T32. He goes all in for 300 more. It’s 300 to you with 1200 in the pot. You are holding TT, so you flopped top set, but the board is suited, so you may be behind to a flopped flush. Should you call?

Even if your opponent flopped a made flush, you are only a 65.5-34.5 underdog (about 2-1). A quick pot equity calculation tells you that you have 1200*34.5%= $414 equity in this pot, and it’s only $300 to call. The fact that your opponent is al
