This is the biggest update so far and it brings many new features. The schedule for the release is as follows:. Next release cycle will be focused on polishing new features introduced in this one and making plug-in system more friendly for programmers.
Our goal is to make plug-ins accessible for hobbyist programmers as well. Below is the list of new things and changes. As the list is long the links to explanation GIFs and pictures are provided as links so it's easier to read:. There is now an option to save incomplete trees.
Those saves are about 50xx smaller than full trees depending on the tree so they load very fast and the delay when browsing and calculating rivers on the fly is barely noticeable. You don't need to click anything or worry about anything when browsing.
Recalculating of missing parts of the tree happens automatically. You can configure desired accuracy for on-the-fly solving as well. You can open it with ranges at any point in the tree or you can insert your own.
The range vs range equities or range vs any chose subset are calculated instantly and exactly.

You can stop the solver at any point, set the strategy in given node, lock it and resume solving. In addition to strategy, ev and current range you can now see equity of every combo against current range of the opponent at any point in the tree:.
For example you can ask for a report for 2nd barrel and PioViewer will generate a spreadsheet with all 49 turn cards and frequencies of 2nd barrel on them. It's now possible to write plug-ins for PioViewer. The parameters are saved in corresponding. If you load a. PioViewer is way faster and almost everything should refresh instantly while you browse. The adjustments are also saved with the trees. It's now possible to select specific combos.
Suited hands or offsuit with chosen suits. The interface is dead simple: you choose the suit for higher card and lower card and the selector displays only those combos for you to select from. This option makes the viewer update results immediately when browsing the tree. You don't need to click to refresh anymore.Still many players continue to stubbornly use their inadequate pre-flop strategies that lead to structural imbalances in their ranges post-flop, and consequently they are open to being easily exploited.
Allow me to start from the beginning…. As I said earlier, your hand selection will be heavily influenced by your position. Your position determines how much information you will have during the hand. When you are under-the-gun you have to act before seeing what anyone does. This is a huge disadvantage if your goal is to steal the blinds. As a result, you must play much more conservatively from early position.
Remember that there can be up to nine other players that have a say in what happens after you raise. Conversely, if it folds around to you on the button, you have a huge advantage because you know that there are only two players left to prevent you from stealing the blinds. You can raise many more hands, especially if you know how the blinds will react to your raises. So how do we choose a default range of hands to play from each position?
A default range is what we will use without information on our opponents. Let me save you a lot of time and give you some ranges of hands that have proven to be profitable for me over a large sample size.
Database analysis experts have analyzed millions of hands played by solid professionals and determined which ones should have a long-term positive expectation. The following default ranges are how I interpret their research. There are a lot of hands that will only be slightly profitable on the fringes of a range.
As a result, you should never be afraid to return to a tighter range if my suggestions are putting you in post-flop situations that are making you uncomfortable.
As you improve post-flop, your pre-flop options will increase. Moreover, solid pre-flop decisions lead to better post-flop decisions. Keep in mind that this article is like a pre-flop playbook. Each individual hand is a player and your team of hands is a range. Each hand plays a role in getting your opponent to react differently to your range. I raise all of the pockets pairs because the hands generally go multi-way and I feel that my opponents will make poor decisions when I flop a set.
This range is much harder to use against opponents that will adjust by 3-betting you more often because there are too many weak hands in it to have a balanced 4-betting range. I use this range in very passive games with very deep stacks.I spent a lot of time learning, tweaking and adjusting my 6-max opening raising, calling and 3-betting ranges over the past year trying to identify good, conservative, but strong and aggressive ranges for mainly beginning and struggling 6-max micro stakes poker players.
So after lots of work putting these together, trying to make them as simple as possible to follow, I am here to share them with you. Lastly, while we are 3-bet bluffing from time-to-time, it is not a big part of our game. This is the same for my 3-betting ranges. Our 3-betting range is a strong value-oriented game. You will notice that as our opponents open in later positions, we can 3-bet wider ranges for value, especially against BTN and SB opens.
We do have a 3-bet bluffing range composed of small suited aces, and a few combos of suited connectors. I do not recommend you 3-bet bluff that often unless someone is a habitual blind stealer that folds to a lot of 3-bets over a large sample size.
Also the ranges are too loose for my taste. I am really bad in mathematics and I have some lack of theoretical knowledge. So if I would start building ranges by myself, I would waste a lot of time I could invest in grinding plus I would probably make mistakes and then lose EV preflop. That's why I am asking here how to proceed. I would even be willing to pay for preflop ranges if they are good and if I have ranges for all situations.
Some advice or help would be appreciated. Thanks in advance, Benny. PokerSnowie has very good preflop ranges for all common spots. Their preflop advisor is free. The full program has a free trial. This is just my 2c but I never used a preflop hand chart and I doubt I ever will.

Solvers are very good for studying the preflop and flop strategy, but not so useful for studying the turn and the river. Andres is basically saying that it's less important to play theoretically sound poker or at least a solver's version of theoretically sound poker on the later streets, which got me thinking why is this the case?
GTO stands for game theory optimal. You can learn more about what is known about poker game theory here. It may seem counter intuitive, but the optimal strategy is more complex the earlier you are in a hand. This increased complexity is derived from the immense amount of outcomes possible at the start of the game tree.
This plethora of options makes it extremely hard for us, as mere humans, to determine the correct preflop strategy. Thankfully, some tools have been developed to help us approximate correct preflop and flop ranges PIOSolver and PokerSnowie.
Additionally, our opponents will naturally have more experience playing early streets than the later ones simply because they occur more oftenso we should expect them to make fewer fundamental mistakes on the earlier streets, and thus it is more important for our strategy to be theoretically sound.
Consider the hand QTo. If you are just started out in poker, this might seem like a good hand to play from middle or even early position. Two broadway cards, it can make straights why not? Well, after mass database analysis and, later on, PokerSnowie simulations, we know that this hand is not a profitable open-raise because doing so leads to many bad outcomes in the later parts of the game tree such as losing a bunch of money with a dominated top pair.
NOTE: Want to take the guesswork out of your preflop game? Get preflop charts for almost every situation when you join the Upswing Lab. Learn more now! We as humans cannot see that far ahead. They know which line is preferable for each hand, sometimes for reasons that are effectively impossible for us to deduce, because they have seen what happens at the end of the game tree over and over and over again. When the big blind checks to you, what would you do? So, let's plug this situation into PIOSolver to see its solution I'll summarize the solution below the image for those of you who don't use solvers :.
JJ and our specific combo of JJ are highlighted in red. Click here to enlarge the image so you can see the details. We can speculate why:.
Note that the JJ combinations that have a backdoor flush draw are bet at a higher frequency. This is likely because they have slightly higher equity and it sucks less to get raised while holding a heart. If we use the same logic as in the previous section, it's easy to see why we can rely more on our intuition on later streets:. In this river spot, it's extremely difficult for your opponent to be bluffing because almost all of his possible semi-bluffs flush draws, J9, etc.
Unless he is a very high-level player who planned for such a situation on earlier streets, he will very rarely show up with a bluffing hand. Of course, the solver will reach this river with enough hands to bluff with, as you can see in the picture below:. The hands highlighted in blue are bluffing hands that most humans would never reach the river with.
Due to its extremely developed visibility across the game tree, the solver was able to reach this river with relatively many combinations of hands that can profitably bluff. You can see that it bet twice with some pocket pairs 55, 77, 99 and some flopped bottom pairs KTs, JTs, T9s which it now bets at some frequency.The preflop advice table is a great tool to visualize PokerSnowie's preflop strategy in one glance. The table displays one field for each of the different hole card combinations: the diagonal covers the pocket pairs, the upper right triangle the suited cards and the lower left triangle the off-suited cards.
The colour code indicates the advised action, green for raise, yellow for call and white for fold. If a number is displayed in the field, this is the percentage of times this hand should be raised.
It is possible that some hole card combinations are not in the preflop range anymore. If you have previously raised and it is your turn again, you would not be holding 72o, for example, because you would have folded it already. Those fields are greyed out. However, it is still possible to see how PokerSnowie would continue with these hands, by activating the option 'show full table'.
The default table is the one for the proposed bet size, the bet sizes PokerSnowie considers as best. The hand range feature calculates a list of all hands that PokerSnowie would hold, given the circumstances of the game. At the top of the window the hand range is split by hand type. At the bottom all individual hands are displayed. They are grouped by hole cards that are considered the same. For example, on preflop all 12 combinations of JTo are grouped together and all 4 combinations of JTs.
The 'Combinations' column tells you the number of combinations remaining from that group.
What To Open-Raise Preflop?
The combinations value may be further decreased by a certain percentage if PokerSnowie would have made the move the player made. The next column specifies the hand type, and the last column the draw type if the situation is not on the riverfor each hand.
Please note that it can happen that no hands are found. That means that PokerSnowie would not have played the same way as the player did with any hand. This feature is only available for the player to act. Selecting one of those ranges provides distribution information about the hand type and details for all hands that comprise the corresponding range.
By default PokerSnowie selects the bet size it considers best, but it can be switched manually to see ranges for alternative bet sizes. It is also possible to see how PokerSnowie would play hands that are not in its hand range anymore. Clicking 'show all hole cards' provides the evaluations for all hole cards, independent of the hand range. Online Manual Index. More videos available on our YouTube channel.
