In this talk I will argue that the NMSSM with strongish self couplings can very naturally give a Higgs boson as heavy as 200-300 GeV and at the same time provide a dynamical origin for the mu term. The generated mu term is of the order of the mass of the Higgs and thus do not imply any tuning nor contradiction with current experiments. I will discuss the fine tuning of the model with respect to various experimental constraints from LEP direct searches, precision data and direct dark matter searches. I will show that the model naturally accommodates the current limits and I will discuss the main features of the signatures at the LHC including the implications for the 2010-2012 run.
