The available ranges are listed under the main folder. The ranges are grouped by KO:Stack ratio and stack distribuiton.
1:1 KO:Stack ration means 1 KO for every starting stack. 1,5:1 means 1,5 KO for every starting stack. Currently only 1:1 ratio is available, others are coming soon.
In the even stack ranges every player can bust everyone. On the other ranges only the bigger stack can bust out the smaller stack.
The second step is to select one effective stack from the available stack sizes within the range. A new list with the available positions will be opened. You can choose the position of the opening player there.
Selecting a position will list the available action of the opening player. At the same time, their range is displayed on the left. You can continue by selecting one from the available actions.
After selecting the action of the opening player, you can choose a player from the remaining players at the table. Clicking on any player will give you the defending range.
A complex 4-bet spot will look like this.
