We propose a kinematical enhancement of the tt charge asymmetry at the LHC by selecting events with the tt centre of mass frame highly boosted along the beam axis. This kinematical selection increases the asymmetries and their significance up to a factor of two in a rather model-independent fashion. Hence, it can be a perfect complement to enhance model discrimination at the LHC.
