We study the decay Ω-→Ξ-π+π- in heavy-baryon chiral perturbation theory. At leading order, the decay is completely dominated by the Ξ*0(1530) intermediate state, and the predicted rate and Ξ-π+-mass distribution are in conflict with currently available data. It is possible to resolve this conflict by considering additional contributions at next-to-leading order.
