We explore the possibility of studying B→ π lν semileptonic decays at large recoil momentum. Our methods include the use of a random wall source for the pion to reduce statistical errors, and different smearing functions are used for the B meson to improve the overlap with the ground state. We also study the possibility of reducing the pion momentum by using a nonstationary B meson in the framework of moving NRQCD.
