We present a measurement of the anisotropic and isotropic Baryon AcousticOscillations (BAO) from the extended Baryon Oscillation Spectroscopic SurveyData Release 14 quasar sample with optimal redshift weights. Applying theredshift weights improves the constraint on the BAO dilation parameter$\alpha(z_{\rm eff})$ by 17\%. We reconstruct the evolution history of the BAOdistance indicators in the redshift range of $0.8<z<2.2$. This paper is part ofa set that analyses the eBOSS DR14 quasar sample.
