  In the "intense--coupling" regime all Higgs bosons of the Minimal
Supersymmetric extension of the Standard Model (MSSM) are rather light and have
comparable masses of O(100 GeV). They couple maximally to electroweak gauge
bosons, and for large ratios of the vacuum expectation values of the two Higgs
doublet fields, tan\beta, they interact strongly with the standard third
generation fermions. We present in this note a comprehensive study of this
scenario. We summarize the main phenomenological features, and the accordance
with the direct constraints from Higgs boson searches at LEP2 and the Tevatron
as well as the indirect constraints from precision measurements will be
checked. After the presentation of the decay branching ratios, we discuss the
production cross sections of the neutral Higgs particles in this regime at
future colliders, the Tevatron Run II, the LHC and a 500 GeV e+e- linear
collider.
