Nikos Pergialis & Manos Pantavos

The Greek composers Nikos Pergialis and Manos Pantavos are creating together nice problems, in miniature or meredith form.
In this post we present five original problems by them, all direct-mate two-movers, and we thank them very much.

Strange twinning

The following problem has various stipulations. Let us say we have five twin problems.
Each stipulation results in some tries and a single-variation solution.

The solution of each twin is just a try in the next twin. Enjoy!
