Navigation between strategy tables:

- PreflopWhiz is available for many stack sizes and rake structures both for Cash games and MTTs. To navigate between these, we created customizable menu bars for structure changes and the BB panel for stack depth changes.
- On the top of the page, you can find the menu bars to change structures. These can be customized in Settings.
- To customize the menu bars enter Settings. Under the "Quick access to games in the navigation bar" section set your favored rake/ante structure and choose a default table for the link you want to modify.⁣⁣ Repeat this action until you have all the links according to your preference.⁣⁣ Links will be updated once you click on another page.⁣⁣

- Within a structure, you can activate any stack size you need by clicking on the buttons in the BB panel below the input bar. You can hide BB buttons you do not have a subscription for in Settings. Additionally, you can use the "All tables" drop-down menu to navigate directly to any table you want.

Every strategy table has a unique stack depth & rake structure attribution. Similar decision points are arranged into categories within each strategy table.

BB after ISO

Our new “Lab” section is designed to create an advanced learning process

• 3 selectable BB stacks and/or open sizes to compare & contrast the differences in the strategies.
• Toggle side cards up and down.
• “Category table filter” to only view which strategy categories you'd like to.
• Buttons to draw random hands within categories.
• Hide results in “Guess mode” to be able to self-quiz yourself.

How to use

1. Select whether you’d like to compare 4 or 5 card strategies.
2. Select the three formats you’d like to compare. You can choose and mix any rake structure, stack depth and open sizes.
3. Enter the starting hand you want the strategies to be displayed for. You can also draw a random hand by clicking on any category button. The up and down buttons above and below the hole cards are used to adjust individual cards. For example, changing AKJT to AQJT or AKJ9 etc.
4. You can change to EV mode to display expected values or to Ag mode to view aggregate strategies for each situation.
5. You can use the “Category table filter” to hide unwanted strategy categories.
6. Enter “Guess mode” if you would like to self-quiz yourself. If you turn this on with the toggle button in the top right corner, results won’t be displayed automatically when you query a new hand in any way. After you’ve guessed the results, you can reveal the strategies with the “Show results” button.
   (For example, set stacks to 30bb 50bb 100bb, set the “Category table filter” to only show RFI, click a random hand button, and ask yourself at which position and stacks it opens/folds. Click on “Show results” to display the correct answers.)

Learning tips and example scenarios from PLOBeast creator TCfromUB

Turn on EV mode to find close fringe scenarios. Keep these in mind when making adjustments depending on your opponents. An example might be a very close decision at rfi. If you find yourself at a tight and/or easy table you could elect to raise, instead of a default fold. Also keep in mind the hand's response to further action, like facing a 3bet. Does the next closest scenario clearly call or clearly fold?

In this example you can see in some scenarios where this hand folds or mixes (at 40bb and 50bb), however the EVs are close. As a default, one would choose to follow the strategy, although at a tight table one adjustment could be to open these hands at EP. Then looking at "rfi vs 3bet" category we see that facing 3bets the EVs in all scenarios is a clear call. A takeaway from this is that if you perhaps mistakenly opened a hand from a fringe rfi spot, this category of hands is very likely to still call vs a 3bet. Sometimes you might find yourself in a scenario of uncertainty about whether to rfi, and THEN what when faced with a 3bet?

1. 40bb MP rfi & 50bb EP rfi very close but default folds, tight table = open.
2. 40bb CO v BU 3b, clear call by a wide margin, thus if you chose to rfi MP at 40bb, also a clear call vs 3bet.

---

Here is another example of the opposite!

1. 100bb UTG rfi, very close but default fold.
2. Tight table = open all positions.
3. Vs 3bet, looking at MP strategies, it's an obvious fold vs all position 3bets. So, we'd open UTG, and clear fold vs 3bet.

Filter syntax

Range view allows you to filter the displayed hands using a powerful but easy-to-learn syntax. All the hands are shown by default, however you can filter them by to a wide variety of critera by entering a filter expression into the text box at the bottom of the window.

Basics: ranks and suits

Characters “AKQJT98765432” represent ranks and “wxyz” represent suit variables.
The rank and the suit of a card should be consecutive, but their order is arbitrary.
A simple expression consists of a single range, which represents a set of hands.
For example, “AxKxQyJy” is a valid range, therefore it is a valid expression.

Wildcards

Unspecified cards or properties (an omitted rank or suit per card) are considered as wildcards. There is no way or need to mark them explicitly.
For example, range “AA” should return all hands with an ace pair, and range “Axx” all the hands with a suited ace.
There is a single exception: the range “*” means all hands.

Rank variables

All non-reserved characters are considered as rank variables. “SDFGH” seem reasonable choices as they are next to each other on the keyboard.
Ex. range “SS” means a pair, range “SxSyDxDy” means a double-suited hand with two pairs

Operators

Construction of more complex expressions is possible using multiple ranges and set operators.

1. ! - set difference / NOT (left-associative)
2. : - set intersection / AND (left-associative, commutative)
3. , - set union / OR (left-associative, commutative)
4. () - parentheses (ex. “(aa, kk) : !rrr").

The order of evaluation is: () > ! > : > ,

It is important to remember, that variables have a range scope. They can be bound to different ranks and suits across different ranges, because ranges are evaluated independently. Ex. if you want to describe a single-suited hand with no suited ace, write “xx !Axx” instead of “xx !Ax”, because the latter range has no idea what you have meant in the first.

Ascending ranges

Ascending ranges are indicated with a trailing “+”.
Ex. “9876+” is equivalent with “(9876, T987, JT98, QJT9, KQJT, AKQJ)”.

Macros

Macros are shorthands for common expressions. They are indicated with a leading “$” and can be used within complex expressions as well.

Miscellaneous rules

Spaces are ignored. Evaluation is case insensitive, so ranges “AxKxQyJy” and “axkxqyjy” are semantically identical.

Tip 1 Always use the appropriate strategy table regarding rake/ante structure and stack depth.
GTO Strategies can vary to a large extent depending on rake/ante and stack sizes. You should learn your GTO strategies from the simulation data that is most similar to the actual games you are playing.

Tip 2 Do not forget these are GTO strategies.
Utilizing strategies suggested by PreflopWhiz might not be the best decision if your opponent's frequencies vastly differ from GTO. Think it through and rely on your poker knowledge to make the best decision adapting to your opponents.

Tip 3 You can compare the decision's EV-s in any situation.
If you think a decision is close, you should check the EV difference. (To do this simply double click on any category and EV-s will be displayed there.) If the EV difference is small, depending on your opponent's frequencies, it may be better not to choose the suggested strategy. Using this feature is very helpful playing MTT-s, where our strategies do not consider ICM. It may be better to ditch some of the lower EV plays when ICM is in play!

Tip 4 When utilizing short stack strategies against opponents who are short stacked and you are deeper, always consider that you might have to risk more chips against other opponents than what was solved in the simulation. Therefore, use these strategies with great care! For example, let's say you have 40BBs MP and a 10BB opponent raises from EP. Our 10BB strategies assume that you also have 10BBs and when you reraise you will not risk more than that.

Note In some of our strategy tables, there are a few situations where the call option was not given to the solver.
This is the case when the call cell for a situation (or a few) is marked with "x" but the rest are filled in the same category. In these cases, you might consider whether calling would have higher EV than raising/folding. You can do this by comparing the results with similar situations in the same category where all three options were allowed.

Note Despite our best efforts to carefully check strategies before publishing them, data processing errors may occur.
