What Is Isolate?
Isolation raises are commonly used against limpers, particularly recreational players perceived as weaker, with the goal of eliminating other players from the pot and gaining a heads-up positional and skill advantage. The isolation raise typically needs to be larger than a standard open to successfully price out other potential callers behind.
Examples
A player raises significantly larger than usual after a weak player limps in, hoping to isolate and play the hand heads-up.
A regular isolates a known recreational limper with a wide range of hands, seeking to leverage a big skill edge in position.
Strategy Tips
Size your isolation raises larger than a standard open, especially with multiple players left to act, to effectively narrow the field down to the target limper. Widen your isolating range against known weak players, since the skill edge and positional advantage of playing heads-up against them adds significant value. Be selective about which limpers to isolate, focusing on the weakest player at the table rather than isolating against strong regulars who limp for deceptive reasons. Adjust your isolation strategy based on your position relative to the limper, isolating more aggressively when you'll have position for the rest of the hand.
