In this article we consider the Cauchy problem with large initial data for an equation of the form (partial derivative(t) + partial derivative(3)(x)) u = F(u, u(x), u(xx)) where F is a polynomial with no constant or linear terms. Local well-posedness was established in weighted Sobolev spaces by Kenig-Ponce-Vega. In this paper we prove local well-posedness in a translation invariant subspace of Hs by adapting the result of Marzuola-Metcalfe-Tataru on quasilinear Schrodinger equations.
