What is
Merged
in poker?
A merged range is often described as a range morphology between linear and polarized. Merged ranges often resemble polarized ranges with some medium-strength hands or polarized ranges with some bluffs. The purpose of "merging" is to make the range more robust. A perfectly polarized range is typically vulnerable to min-raises as you can't call your pure bluffs, whereas a perfectly linear range may be vulnerable to overbets and continued aggression as your medium-strength hands can't effectively realize their equity. A merged range attempts to reduce the exploitability of these extreme range constructions by including some medium-strength hands that improve flexibility.
