We discuss the potential of combined analyses at the Large Hadron Colliderand the planned International Linear Collider to explore low-energysupersymmetry in a difficult region of the parameter space characterized bymasses of the scalar SUSY particles around 2 TeV. Precision analyses of crosssections for light chargino production and forward--backward asymmetries ofdecay leptons and hadrons at the ILC, together with mass information on chi^0_2and squarks from the LHC, allow us to determine the underlying fundamentalgaugino/higgsino MSSM parameters and to constrain the masses of the heavy,kinematically inaccessible sparticles. No assumptions on a specificSUSY-breaking mechanism are imposed. For this analysis the complete spincorrelations between production and decay processes are taken into account.Comment: new figure added, updated to match the published versio
