    "abstract": "After a brief review of the role three-nucleon forces play in the few-nucleon\nsystems, the chiral-perturbation-theory approach to these forces is discussed.\nConstruction of the (nominal) leading- and subleading-order Born terms and\npion-rescattering graphs contributing to two-pion-exchange three-nucleon forces\nis reviewed, and comparisons are made of the types of such forces that are used\ntoday. It is demonstrated that the short-range $c$-term of the Tucson-Melbourne\nforce is unnatural in terms of power counting and should be dropped. The class\nof two-pion-exchange three-nucleon forces then becomes rather uniform.",
