The scaling limit of planar loop-erased random walks is described by using a stochastic Loewner evolution with parameter κ = 2. In this paper SLE2 in the upper half-plane mathbb {H} minus a simply connected compact subset mathbb {K}subset mathbb {H} is studied. As a main result, the left-passage probability with respect to mathbb {K} is explicitly determined.
