Popis: We present a new technique to decide or reduce instances of Post's correspondence problem. It generalizes balance arguments to a consideration about some special context-free languages which allow the combination with other decision (or reduction) techniques. In spite of its simplicity, the new technique is able to decide more instances than known techniques.
