General Hand Analysis Questions



Question 1:
What are the Sklansky-Karlson Hand Rankings and how are they used?
Answer  In a message board thread (external link), David Sklansky and Victor Chubukov (Karlson) develop a method to rank the 169 possible starting hand based on heads up strength. The results were dubbed the “Sklansky-Karlson All In No Limit Holdem Rankings”, or SK hand rankings.

The SitNGo Wizard uses the SK hand rankings when referring to opponent hand ranges. For example, if you estimate an opponent’s calling range to be 20%, it means you predict he will call with any hand that is in the top 20% of the SK hand rankings.

Note that SK hand rankings are only used in determining opponent opening and calling ranges. The hand range computed in the analysis summary usually does not match the SK hand rankings. The ranking of hands in the computed range varies depending on game situations.

The table below lists the SK hand rankings and each hand’s hand range grouping.

Question 2:
How is the edge in the analysis summary computed?
Answer  The Wizard computes a default Edge% based on two factors:

1. Your effective stack size in big blinds.
2. Your position relative to the big blind.

Your effective stack is the largest amount you can lose on the hand when it is your first turn to act.

When your effective stack (measured in big blinds) is large, your Edge% generally needs to be large to reduce variance. When your effective stack is small, your Edge% generally should be small (or even negative) because you need to take even the smallest advantage.

When your effective stack is small and you are getting close to hitting the big blind, your Edge% should be even smaller (or even more negative) because you situation is becoming more disparate.

The default edge calculation can be completely customized to fit your style of play by using the Edge Editor. Select "Edge editor..." on the Tools menu to edit the default edge. See "Default Edge" in the help reference section for more details.

Question 3:
Why are the Wizard’s results different from other ICM programs?
1. The Wizard accounts for possible overcalls. Other ICM programs assume that once one opponent calls your push everybody else will fold.

2. When you fold, the Wizard accounts for the possibility that other players who are left to act will get all-in. Other ICM programs assume that when you fold, all other players will also fold.

Question 4:
How do I analyze multi-table tournaments?
Answer  First, you will need to create a custom tournament structure with the payouts for the tournament. It’s pretty easy and you can find detailed instructions in the help file.

The load the tournament hand history into the Wizard. When there is still more than one table active, you need to use “Chip EV” analysis mode in the Wizard’s options dialog. This mode values each chip equally.

When you are down to the final table, switch to “ICM” mode in the options dialog. ICM mode is only valid when you get down to a single table.

You can also set the mode on the game view by clicking on the “Options” link in the upper right hand corner.

Question 5:
Can I set a custom opponent hand range?
Answer  No, at this time all opponent hand ranges are based Sklansky-Karlson (KS) hand rankings. You can specify hand ranges either as a top percentage of KS rankings (like top 10%) or as a middle range (like from 10% to 20%).

The problem with supporting user-defined hand ranges is speed, or lack thereof. By using a fixed hand ranking (like the KS rankings) I can pre-compute all the raw hand equity calculations. This permits the SitNGo Wizard to compute the hero’s hand range in a fraction of a second. The same calculation (the Compute All button) takes several seconds in SNTPT. Actually, the speed difference is even greater because SNGPT is only computing heads-up showdowns. SNGWIZ is computing 3-way showdowns in addition to heads-up showdowns.

If user-defined hand ranges were supported, the equity calculations would have to be computed in real-time. Imagine running hundreds of PokerStove solutions every time you open a hand. I fear the performance would be dreadful.

This feature will be added if I can find a workable solution to the performance issue.

However, I am working on what I think will be an even better solution. I recently enhanced the statistics collection program to collect opponent hole cards that are shown down. From this data I will be able to compile the frequency that each hand is shown in various situations. I can use the frequencies to produce a hand ranking based on real opponent behavior. So far I do not have nearly enough samples, but the results look promising.

Question 6:
Warning: A significant branch of the player action tree had to be pruned. What does this mean?
Answer  This warning message means that there is a significant chance (around 10% or more) that you would be called by 3 or more opponents. Since the Wizard cannot compute 4-way showdowns, a player action branch had to be removed from the player action tree. Therefore, the analysis may not be accurate since a significant branch had to be pruned.

Question 7:
Why does the hero's hand range contain different hands than opponent ranges?
Answer  Opponent hand ranges use a fixed ranking order. So a certain hand range percentage will always contain the same hands.

The order of hands included in the hero’s hand range depends on the profitability of each hand. That order will change depending on the situation. For example, small suited connectors will usually rank higher when you are likely to have multiple opponents.
