Abstract
We construct a new family of skein exact triangles for link Floer homology. The skein triples are described by a triple of rational tangles , where is the trivial tangle and is obtained from it by applying positive half-twists. We also set up an appropriate framework for potential construction of further skein exact triangles corresponding to arbitrary triples of rational tangles.
