In this paper, we use the Hirota bilinear method. With the help of symbolic calculation and applying this method, we solve the (2 + 1) -dimensional bidirectional Sawada–Kotera (bSK) equation to obtain some new lump-kink, lump-solitons, periodic kink-wave, periodic soliton and periodic wave solutions.
