In this paper, a natural bijection between multichains of binary paths and shifted tableaux is presented, and it is used for the enumeration of the chains with maximum length from a given path P to the maximum path 1|P|. By mapping chains to shifted tableaux, the main formulas given in a recent paper by the authors for the enumeration of the P - 1|P| chains having only small intervals and minimum length are proved, using some new bijections on shifted tableaux.
