ChipEV 40bb GTO preflop ranges

You can add as many strategies as you like as soon as they fit in 5000 ranges limit. Once the limit is reached, you’ll be notified and you won’t be able to add more solutions. However, you can go to Editor, delete unnecessary folders, and continue adding new solutions.

Original / simplified GTO ranges

Pay attention to the first filter available in every game format: Solution Type. All GTO solutions in the Library are grouped into two types:

  • GTO — original ranges from the solver. Best for deep study and understanding of theory.
  • Simplified GTO — same GTO ranges, but all the frequencies are rounded to the nearest 25% (e.g., 0%, 25%, 50%, 75%, 100%). Easier to use in practice — simpler to remember and apply during play.

In the example below you can compare original and simplified CO Open Raise ranges in a classic 100bb cash game:

As you can see, the difference is barely noticeable — yet the second range is much easier to read and memorize.

Custom preflop strategies

There’s also a third option in the Solution Type filter — Custom. It includes custom preflop range packages from leading poker schools and coaches. These packages typically contain exploit strategies adapted for real games.

Re-Add and Update

If you made changes to the ranges, and want to rollback - click Re-add opposite the selected strategy in the Library. It'll reset all the ranges from this strategy to their original state. It won't affect any other ranges you have in your configuration.

If a package that you previously added has a new version, you'll see an Update button. By clicking on it, you'll update the strategy to the newest version, but, similar to "Re-add" action, you'll lose all the changes you made to the ranges before.
