Abstract

In this paper, we extend the concept of {\it (strongly) keenness} for Heegaard splittings to bridge splittings, and show that, for any integers gg, bb and nn with g0g\ge 0, b1b\ge 1, n1n\ge 1 except for (g,b)=(0,1)(g,b)=(0,1) and (g,b,n)=(0,3,1)(g,b,n)=(0,3,1), there exists a strongly keen (g,b)(g,b)-splitting of a link with distance nn. We also show that any (0,3)(0,3)-splitting of a link with distance 11 cannot be keen.
