Center squeeze can occur under FPTP and two-round runoff with any number of candidates. If the center candidates are close enough together, honest votes will be split between all of them, electing the worst (FPTP) or second-worst (T2R) candidate.

A similar effect can occur under IRV, electing the second-worst candidate, though less extreme, since eliminated candidates transfer votes to nearby candidates, making it harder for them to be eliminated.
