The pressure-temperature phase diagram of the highest-{ital T}{sub {ital c}} organic superconductor, {kappa}-(BEDT-TTF){sub 2}Cu(N(CN){sub 2})Cl is determined, where BEDT-TTF is bis(ethylenedithio)tetrathiafulvalene. Semiconducting, insulating, metallic, and superconducting regimes are seen at pressures below 1 kbar. Superconductivity at 12.5 K and 0.3 kbar {ital increases} by 0.5--1.5 K upon deuteration of BEDT-TTF, in striking contrast to the normal isotope effect determined previously for {kappa}-(BEDT-TTF){sub 2}Cu(N(CN){sub 2})Br.
