abstract = {<p style="text-align: justify;">An $H(2)$-move is a local move of a knot which is performed by adding a
half-twisted band. It is known an $H(2)$-move is an unknotting operation. We define
the $H(2)$-unknotting number of a knot $K$ to be the minimum number of $H(2)$-moves
needed to transform K into a trivial knot. We give several methods to estimate the $H(2)$-unknotting number of a knot. Then we give tables of $H(2)$-unknotting numbers
of knots with up to 9 crossings.</p>},
