PokerRanger2 - Preflop Trainer (NEW, v2.3.0)

Hi SZEBI18,

I am afraid I have never heard of such a behaviour. It might be the case that the software only has limited access to the hard drive. You could try to start PokerRanger as Administrator.

Also, do you have something specific about your system? Some antivirus/firewall software, network drives, access via VPN etc. might play a role here.

So, you probably can also not export a PokerRanger tree and not save/open PokerRanger analysis files, is this correct?

Apart from that, you could add us on Skype: PokerRangerSupport. We might have a look on your screen and check this issue out. It is easier to find the issue if we can get direct visual feedback, although your description seems to say that we will not discover a lot of new information.

I am optimistic that we will solve this.

All the best,
Michael

Hi,

please help me to solve the following problem. I have not found something about dealing with sng tournaments and risk aversion/premium. For example, in the hand

Poker Stars, $6.71 Buy-in (20/40 blinds, 4 ante) hyperturbo No Limit Hold'em Tournament, 5 Players
Poker Tools Powered By Holdem Manager - The Ultimate Poker Software Suite.

SB: 384 (9.6 bb)
BB: 532 (13.3 bb)
MP: 603 (15.1 bb)
CO: 844 (21.1 bb)
Hero (BTN): 637 (15.9 bb)

Preflop: Hero is BTN with A Q
2 folds, Hero raises to 80, SB folds, BB calls 40

Flop: (200) 4 7 7 (2 players)
BB bets 448 and is all-in,

loose and passive player, postflop agressive, in my view call 80% preflop except 8% hands which he raises. He pushes all flush draws and small pairs on the flop. Then my postflop card equity is 44%. I could call this in cash game.

But I have risk premium 10% from ICM Explorer which I have to add to my chips equity needed 40%+10%=50%. So I could not see all the EV calculations for sng tournaments, I compare the equities only.

Maybe it would be good to add a field for manual entering a risk premium from the other tool, which would be included in EV calculations.

Hi strategic12,

you are right, the premium is not considered at the moment and it definitely makes sense to include this.

You can hover with your mouse over particular EV fields. That way, you will see the calculation behind. Maybe, for your own calculations these numbers may be of use. For example, when you only analyze whether a call is +EV or -EV with a given range, you will enter the numbers into PokerRanger, let villain bet and you will enter a calling range for hero. When you hover over the EV for this call (this EV can be displayed by using the options), you will see the calculation.

If ICM explorer says that you need to insert a risk premium of 10%, this essentially boils down to:

(Equity - 0.1) * 648 - (1 - (Equity - 0.1)) * 448 = 0

saying that you have a break-even decision, when the equity fulfills this scenario.

Generalizing this equation and substituting 0 with EV let you calculate the EV reduction based on premium. If I have calculated correctly, you can reduce your EV by:

(Win + Loss) * Premium

So, in you case, (448+648)*10% = 109.6

It maight not be as convenient as possible yet, but with this simple formula you might calculate the risk-premium-based EV reduction. You would have to do this once for a given scenario and just subtract it from the EV. My simple test for that scenario works as well: When I use your scenario and change villains range such that I have 51% equity, the EV is about 110, while 41% Equity leads to an EV of about zero.

In other words: Your EV has to be at least 109.6 to account for an absolute equity risk premium of 10%.

Could I help you? If you need more details or explanations, I can go into detail further.

Nevertheless, your suggestion is very worthwhile and we will make the EV/FE tab more flexible in the future to allow for more and more arbitrary inputs.

All the best,
Michael

Hi,

I am sorry but I do not comprehend where the numbers 448, 648 and 109.6 came from. Why are they so big when EV in your tool is usually within the interval of 0 to 10? All your reasoning seems to me to be worthwhile, so please explain it to me.

Hi strategic12,

no worries!

In your hand history $648 (sorry, my text falsely said $448 before) is the amount that is in the pot after BB bets all-in. That is exactly the amount that you can win, when you call. So, we have to take the probability that you win and multiply it with $648. Then again, if you lose, you will lose your extra investment which is $448 since this is villain's betsize. Now, 109.6$ is just the result of my formula that takes risk premiums into account. In our scenario it means that you need an EV of >110, so that the call is +EV (given a risk premium).

And the EV can be quite high, depending on the equity that Hero has. I have played around with the ranges just to test my formula.

I am not entirely sure how you entered numbers into PokerRanger in your EV/FE tab. The "first action" usually has to be an action that is active, e.g., a bet. So, what we do is setting Player2 (villain) as active player, let him bet with his range and we sit there and call. Let me show you a screenshot of the scenario as I have put it:

Stack sizes do not matter since villain is all-in and you have him covered, so I just put 1000 here...

Notice how I have set "pot before first action" (200BB) and his bet size (448BB).

As you can see, our equity against villain is 43.85%, I have created villain's range according to your description. Instead of using chip numbers, you could also use BB, it does not matter. In my case I have used the chip numbers.

Hovering over the EV for the call (which equals the total EV because there is no folding/raising range in this simple setting), you can see how it is calculated. (you can display the EVs for the single streets with Options -> EV/FE Calculations -> Show EV of single reactions).

Now, my calculation above with risk premium shows 109.6. The green number (32.58) would have to be equal to or greater than 109.6 for your call to be +EV, IF you take the risk premium of 10% into account that ICM Explorer suggests.

I have tested this in the following way: I changed villain's range in a way that we have an EV of about zero. This happened at an equity for us of about 41%. Now, I changed villain's range in a way such that we have an equity of 51%. This should equal our calculated 109.6, if the calculation is correct, because this is exactly the risk premium (41% + 10% = 51%). As a matter of fact the result matches 109.6.

Of course, if you also fill the fold reaction with some hands, the story changes a little bit.

Has this explanation made it clearer to you? Please let me know, if not, I will gladly explain some aspects again. You could also add me at Skype (PokerRangerSupport). However, I think this issue might be interesting for others as well.

All the best,
Michael

Now I know how to use the tool for calling postflop pushes in sng´s. I want to learn how to became in practice in other situations too in the near future.

Thank you!

Hi strategic12,

good to hear that this has been insightful for you.

For other scenarios, just play around a bit with the numbers. If you need further assistance, just let us know anytime. We always care to help you!

All the best,
Michael

Hi everybody,

we release PokerRanger v1.20.2 which detects if PokerStars is opened and freezes functionality until PokerStars is closed again. PokerStars itself assured that no user will get a warning while running this version.

Enjoy! And as always, we are very open to feedback of any kind!

Hi,

would you please help me with this HT 6max Pokerstars hand?

http://imgur.com/B49cshR

The idea is that how a risk premium of 3.86% in the river bet affects EV Player1? Does it change to a + number? And how much?

I have bet twice and want to bet on the river. My EV Player1 is negative. Taking into account risk premium EV Player2 should be at least (11+36)*0.0386=1.8. It is 25. How will EV Player1 change? Is the river push reasonable?

Thank you.

Hi strategic12,

I am not an expert in SNGs, but according to this article ( https://www.pokerstrategy.com/strategy/sit-and-go/chip-value-risk-premium-concept/1/ ) the risk premium is extra equity that we need in order to make a play profitable.

When we apply this concept to this situation, it makes sense to apply this to our fold equity, since we have 0% equity in case we are called and 100% equity in case Villain folds.

Risk premium means that we need to have more equity to make a call profitable than pure chip equity (here: fold equity) because the chips that we gain have less value than the chips that we invest. PokerRanger calculates only the chip EV. But since the chip EV is already negative, some risk premium would incline us even more to fold.

tl;dr: chip EV does neither increase nor decrease, but taking risk premium into account, the fold should be even clearer.

I hope this answers your question!

All the best,
Michael

Hi,

thank you for your reply.

As I learned how to adjust Pokerranger´s EV of Player when I call in a tournament a year ago, I do not know how to do it when I want to push.

Actually, the hand was played as follows.

Poker Stars $1.40+$0.10 No Limit Hold'em Tournament - t10/t20 Blinds + t2 - 6 players - View hand 3010928
DeucesCracked Poker Videos Hand History Converter

BTN: t500 M = 11.90
SB: t500 M = 11.90
BB: t500 M = 11.90
Hero (UTG): t500 M = 11.90
MP: t500 M = 11.90
CO: t500 M = 11.90

Pre Flop: (t42) Hero is UTG with T 8
Hero raises to t40, 4 folds, BB calls t20

Flop: (t102) J 8 A (2 players)
BB checks, Hero checks

Turn: (t102) Q (2 players)
BB checks, Hero checks

River: (t102) 3 (2 players)
BB bets t52, Hero raises to t458 all in, BB calls t406 all in

The article, you mentioned, is very interesting. I want to seek the possible way to connect maybe Pokerranger or other tool with a tournament ICM tool for calculating calls and bets/pushes.

I do not know of the other tools' features. PokerRanger will give you the chip EV.

Maybe, other tools can be combined in the way that they accept the chip EV as an input. All in all, playing around with values, getting an overview and designing your ranges might be a a good task for PokerRanger because it is quite comfortable in those areas.

Hi,
i am trying to use PokerRanger for EV/FE Calculations. But my problem is program force closing itself very often. It is very hard to use it when you are doing complex calculations and suddenly you lost all input because program closes itself.

I tried it on Win10 and Win7 and problem is the same. Any idea what might cause this problem?

Hello PumaPerez,

this issue seems very rare, I am afraid. Is there any specific operation that is ongoing when PokerRanger closes, maybe an equity calculation? You can try to disable automatic equity calculations and check whether the problem keeps coming up.

Best regards,
Michael

Hello,

I have the same issue. I would say that it crashes every 10 minutes or so. Would any technician deal with it, please?

Hello strategic12,

which operating system do you use and is there any specific action that occurs just before the crash? Do you do anything specific?

Here are some things that are worth trying:
1) deactivate "automatic equity calculation" in the options
2) make sure that you have the latest graphic device drivers installed; this might especially be an issue with Windows10
3) make sure that you have enough system memory, might this be close?

Which operating system do you use?

Best regards,
Michael

I use Windows 10. I did the usual actions as choosing how did a board hit a player and EV/FE calculations. I had OpenOffice opened as well.

1) The crash happened in both situations at automatic calculation.
2) I have reinstalled the latest graphic driver, but it has not helped.
3) I have 4GB RAM.

Have you tried deactivating automatic equity calculation?

4GB RAM could be really, really close because Windows10 alone might need more memory than that. In the case that any software demands more memory than that, a swap file is generated and used. Nevertheless, crashes can occur when Windows is unable to allocate memory.

Yes, I have tried it.

So, do you suggest to enlarge my RAM to 8GB?

Hello strategic12,

RAM is a hardware part, so you need to check the specifications of your laptop or desktop to know whether or not you can extend or exchange your RAM.

However, I need to say here that it is still not certain that this is the issue. On the other hand, it is always good to have more RAM

Best regards,
Michael
