Emmanuel Manolas (3)

Today's post is relevant with the theme Rex solus (=King alone), in which the black King is alone on the chess board. The white forces threatening him will eventually win and the solvers must find the way.

Below we present eight original compositions of the Greek composer Manolas (the owner of this blog).
The Problems 367 – 373 are two-movers and the Problem 374 is a three-mover.

Their solutions will not be difficult to find. Please try to solve them, and then send a comment with the eight keys.
