comment Blow-ups followed by contractions
Do you mean "...except for Kodaira dimension $-\infty$" right? Unfortunately my case of study is a ruled surface.

comment Proof of the existence of Lefschetz Pencils.
Yes the first part of the proof follows from Bertini's theorem. But my trouble is about the singularities of the fibers.

comment Proof of the existence of Lefschetz Pencils.
Probably you are right, on books there is only one $-$. But on pieces of papers I use to write a "long dashed line" so I copy the same "error" on latex. However the important thing is that I mean simply a rational function and nothing more.
