We present direct observation of twin boundary pinning and Lorentz force induced flux motion in twinned, untwinned, and oxygen deficient crystals of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}}. We find that twin boundaries act as strong pinning centers only when the vortex lines are pinned within the twin boundary planes. In addition, we find anomalous broadening in the superconducting resistive transition in magnetic fields in an oxygen dificient crystal where T{sub {ital c}}{lt}30 K.
