Runouts Clustering—sounds pretty elaborate and technical but what’s the gist of it and how would it help someone to improve their own game?

In each poker hand with two players, there are 49 different possible turn card runouts (48 on the river). Theoretically, we have a different strategy for each one of them, just like our opponent. For very similar runouts however, it’s well-known that the strategies can be approximately the same.

When describing a spot, we often generalise it with statements like “high cards are very bad for the OOP player” or “low cards hit the BB’s calling range”. You wonder though if there are runouts that are quite different from each other, but can still be played the same? And if so, why exactly is that the case and how far can we simplify our strategy without losing any EV?

With the runout clustering algorithm now included in Poker Scientist, you have the ability to answer exactly that! Simply calculate the cluster for any situation you want and discover new insights when studying different spots.

How does the Runout Clustering work?

In his master thesis in theoretical physics about imperfect information games, Poker Scientist developer Samy89 developed a parameter which measures strategical differences between two players on the turn and river.

The team at Poker Scientist built on this knowledge to create an algorithm which groups similar strategies together without affecting the quality of the solution.

What is Poker Scientist?

Poker Scientist helps you understand the principles of poker as efficiently as possible.

The browser-based software gives you instant access to a GTO gameplan, containing billions of strategies for every relevant heads-up scenario. The gameplan was developed with simplification in mind, with Clustering offering a whole new way of understanding and internalising new strategies.

Poker Scientist’s gameplan is calculated using computers that are several orders of magnitude more powerful than any desktop PC. The highly accurate solutions use the optimal number of bet and raise sizings. Solutions with this accuracy are not achievable for the average solver user on their home PCs.

Through two simplifications in the form of Line Elimination and Runout Clustering, Poker Scientist managed to overcome one of the major problems other solver tools have when it comes to learning and developing your own game efficiently.

Altogether, Poker Scientist offers you a GTO game plan with an innovative approach that’s going take your poker game to a whole new level.

Made Hand Distribution

Understanding what kind of hands you should hold in certain situations is an essential skill to improve your own game. The Made Hand Distribution feature in Poker Scientist will help you acquire and hone this skill.

It contains 18 different hand categories, with possible categories for example being top pairs, flushes or straight draws, as well as two different distributions:

How often a hand group goes into a specific action

How likely it is to have a specific hand type in your current range

Check out the following YouTube video by Poker Scientist developer Samy89 to learn more about the feature and how it can help you to improve your game:

GTO Bot with human tendencies

Playing against a balanced GTO bot is a great way to learn, but there’s also a lot to learn by training against an opponent with human tendencies. Poker Scientist has developed two opponents with human-like play styles, with one opponent having a tight gameplan, the other an aggressive gameplan.

How does it work?

made hand distribution The new Training Mode with a tight and aggressive opponent

Both opponents still use a GTO strategy as the foundation for their gameplan. The logic implemented for the tight/weak play styles follows observation of human behavior: a real player increases the tightness of his strategy in more complex situations.

For the tight opponent, the gap between their strategy and the balanced GTO strategy is larger on the river than on the flop, leading to some new behaviors, like a stronger checking range, reduced bluff frequency/value heavy ranges etc. The aggressive opponent does the opposite, making heavy use of blockers to apply pressure, bringing you into tough spots very often.

To see how well you perform against the different opponent types, you can now choose these specific styles in training mode, allowing your to adjust your general game plan and improve your approach against them.
