Full explanation
To isolate is raising to play heads‑up against one opponent.
Explanation. Isolation raises are used when you want to play against a weaker player who limped or called—raising to “isolate” them. The term comes from isolating in a smaller player pool. Strategic isolation simplifies decisions and maximizes your edge. It’s commonly used in cash and tournament play when opponents are loose or non-aggressive.
