We re-examine higgsino pair production in association with a hard QCD jet atthe LHC. We focus on \ell^+\ell^- +MET +jet events from the production andsubsequent decay, \tchi_2^0\to\tchi_1^0\ell^+\ell^-, of the heavier neutralhiggsino. The novel feature of our analysis is that we propose angular cuts toreduce the irreducible background from Z(-> \tau\bar{\tau})+jet events moreefficiently than the m_{\tau\tau}^2<0 cut that has been used by the ATLAS andCMS collaborations. Additional cuts, needed to reduce backgrounds fromt\bar{t}, WWj and W/Z+\ell\bar{\ell} production, are also delineated. Weevaluate the reach of LHC14 for 300 and 3000~fb^{-1} and stress that thedilepton mass distribution would serve to characterize the higgsino signal.
