 (Joint work with Peter Feller and Lukas Lewark).  A knot is called squeezed if it is a slice of a minimal genus, oriented, connected cobordism from a positive to a negative torus knot.  Many popular classes of knots are squeezed.  At most six knots of ten or fewer crossings are not squeezed.  The Lipshitz-Sarkar stable homotopy type for Khovanov homology provides a (surprisingly?) effective means of obstructing knots from being squeezed.  I'll explain all this; no prior knowledge of anything assumed.  I'll also advertize a cash prize of 271 swiss francs.
